this might help if it is actually broken in the meantime (from chatgpt)
Method 3: Edit the setup.ini File Manually Download the Latest Cygwin Setup Files: Obtain the setup.ini file from the Cygwin repository or mirror. Edit setup.ini: Open setup.ini in a text editor and manually ensure that the package version you want to keep is correctly listed and not marked for update. Run Cygwin Setup: Use the modified setup.ini to install or update packages according to your requirements. Example Workflow Using apt-cyg and Cygwin Setup Here is a step-by-step approach to managing packages with apt-cyg: Install apt-cyg: bash Copy code wget https://github.com/apt-cyg/apt-cyg/raw/master/apt-cyg install apt-cyg /bin Check Installed Packages: bash Copy code apt-cyg list Avoid Upgrades: Avoid running apt-cyg update and apt-cyg upgrade if you want to maintain current versions. Use Cygwin Setup for Pinning: Run the setup executable, select the "Keep" option for the packages you want to prevent from upgrading, and reconfigure Cygwin as needed. Summary Direct Pinning: apt-cyg does not directly support version pinning. Workaround: Use the Cygwin setup tool to select "Keep" for specific packages to prevent them from being upgraded. Manual Management: Avoid running apt-cyg upgrade commands to maintain current package versions. While apt-cyg simplifies package management, leveraging Cygwin's setup tool and manual methods are necessary to effectively control package versions and prevent unwanted updates. You said: how to install with apt-cyg and how to avoid upgrade with apt-cyg ChatGPT said: ChatGPT apt-cyg is a command-line package manager for Cygwin that simplifies the process of installing, updating, and removing packages. However, it does not directly support pinning or holding packages to prevent them from being upgraded, similar to apt-mark hold in Debian-based systems. Here’s a guide on how to use apt-cyg to install packages and avoid upgrades: Installing Packages with apt-cyg Install apt-cyg: First, you need to install apt-cyg if you haven't already: bash Copy code wget https://github.com/apt-cyg/apt-cyg/raw/master/apt-cyg install apt-cyg /bin Update Package List: Before installing, update the package list to ensure you have the latest package information: bash Copy code apt-cyg update Search for Packages: If you are unsure of the exact package name, you can search for it: bash Copy code apt-cyg search package-name Install a Package: Install a package using the install command. For example, to install wget: bash Copy code apt-cyg install wget Avoiding Package Upgrades with apt-cyg apt-cyg does not have a direct mechanism to prevent specific packages from being upgraded. Here’s how you can manage this situation: Method 1: Avoid Running Upgrade Commands Avoid Upgrade Command: Simply avoid using the apt-cyg upgrade command, which updates all installed packages to the latest versions. If you don’t run this command, your installed packages will not be updated. bash Copy code apt-cyg upgrade Manually Manage Updates: If you need to update other packages but want to avoid updating specific ones, you’ll need to manually handle package management. Method 2: Use Cygwin Setup Tool for Pinning To effectively hold specific package versions, you might need to use the Cygwin setup tool instead of apt-cyg: Download Cygwin Setup: Go to the Cygwin website and download the Cygwin setup executable (setup-x86_64.exe or setup-x86.exe). Run Cygwin Setup: Execute the setup program. Set Packages to "Keep": In the package selection step, locate the packages you want to pin. Set these packages to "Keep" instead of "Default" or "Install." Complete the Installation: Continue with the setup process to apply these changes. The "Keep" option ensures that these packages are not upgraded. Method 3: Manually Prevent Upgrades Use setup.ini for Manual Management: Download or locate the setup.ini file from your Cygwin repository. Edit this file to ensure that the package versions you want to keep are listed as you desire. Run Cygwin Setup with Modified setup.ini: Use the modified setup.ini to run the Cygwin setup and maintain your package versions. Summary Installing Packages: Use apt-cyg install package-name to install packages. Avoiding Upgrades: To prevent upgrades, avoid running apt-cyg upgrade. For more precise control, use the Cygwin setup tool to pin packages by selecting "Keep." Manual Management: Edit the setup.ini file or use Cygwin's setup program for detailed package version management. thanks, jim Sent with Proton Mail secure email. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

It seems that the best approach for Chinese translations would be to:
- add spaces at sentence or word breaks in translations before 35 or 45 bytes,
if that is the length unit, worth of characters are output in each column; or
- add a language dependent line breaking strategy, to honour characters not to
be placed at the beginning or ends of lines or split; or
- split between characters, as with long strings in other languages.

Gilbert, you can change the install path of Cygwin64 at install-time to be C:\cygwin. There's no requirement for the 64-bit version to be installed in a "cygwin64" directory. Alternatively, you could let it install into C:\cygwin64 and then make a Junction or Symbolic Link (e.g. using mklink in a Command Prompt) from cygwin to cygwin64, but if it were me I'd probably go with your original intention. -- Dan Harkless http://harkless.org/dan/ -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

Hi Gilbert,
No need to rename the directory as the Cygwin 64 bit will be installed
in C:\Cygwin64 folder
Attached the script that I use to reinstall my system on different computers.
It can be adapted to duplicate the 32bit in a 64 bit installation
Assuming your file list is not longer than 32K, this should work :
chmod + x cyg-reinstall.sh
sed -e "1d" /etc/setup/installed.db | sed -e "s/ .*$//" > filelist.txt
./cyg-reinstall.sh -f filelist.txt
cp cyg-reinstall-x86.bat cyg-reinstall-x86_64.bat
sed -i -e "s/setup-x86.exe/setup-x86_64.exe/" cyg-reinstall-x86_64.bat
if the "filelist.txt" is too long you can split in multiple chunks, like:
grep -v "^lib" filelist.txt > nolib-list.txt
grep "^lib" filelist.txt > lib-list.txt
I usually need to split mine, as my installation hit the 32K limit of
command line
wc -l *.txt
2608 filelist.txt
1297 lib-list.txt
1311 nolib-list.txt
ls -1s *.txt
40K filelist.txt
20K lib-list.txt
20K nolib-list.txt

[QUERY] Help With Semaphore Error on Windows : Cygwin
Hi All,
Could I request for some help on some code?
I ran into an error with semaphores with some book code using Cygwin on
Windows.
The code will throw an error with sem_post().
I compiled it with gcc -o memwriter memwriter.c -lrt -lpthread
$ ./memwriter
Shared memory address: 0x6fff [0..511]
backing file: /dev/shm/shMemEx
semptr is address 0x7cc18 with value 0
SEM_VALUE_MAX is 1147483648
sem_post: Invalid argument <--- ERROR
According to feedback, the above error does not turn up on Linux.
May I know if this is supposed to happen on Cygwin on Windows?
If not, how can I solve this?
I've also attached the code for reference.
Thank you.
Kind regards,
YEO Kai Wei

Definitely no. You'd have to invent a "better word" first and that would be
a whole new layer of explanation.
I'd vote for removal of -M for unattended operations instead. (I.e. make -q
and -M mutually exclusive.)
I mean, this is an unattended operation, right? You HAVE TO be explicit in
what results are expected from it.

Ah, okay. I think I hit this with `-M` and assumed -- evidently incorrectly -- that the same behaviour would exist for `-q`. I agree the current text is entirely accurate for the fully non-interactive mode. I think this caught me out because I frequently run with `-M` -- I don't care about most of the options, but I do want to see what packages are about to be updated -- and I almost never want to use the download-only or install-only modes. But I used `-L` as a one-off when I was uninstalling and reinstalling a bunch of packages and didn't want to hit the network every time, then forgot about it. And it wasn't until I was musing about the fact that I hadn't seen any package updates for a few weeks when trying to do my regular updates with `-M` that I realised what had happened... Given all that, I think everything seems sensible except for the fact that `-M` doesn't follow the same behaviour as `-q`. > > In particular, the fact that the two options currently say they will > > "only" do their action, and that the default is to perform both, lead me > > to believe (a) the options were mutually exclusive and one would > > presumably override the other, (b) this was probably a legacy from > > before setup.rc stored the previous action, and therefore (c) if I was > > running setup with `-q` or `-M`, there was no way to get the supposedly > > default "do both" behaviour; I'd instead need to go through the full > > GUI. > > > > Having now seen how this setting is stored, I've realised I can just > > call setup with `-DL` and it'll perform both actions again.

Probably what's wanted is to remember the state of those checkboxes, if
this isn't the first time setup has been run?
That's a feature silently longed for for a loong time. :) But this is such a
low priority, very few people actually mentioned it in the past years.
It could usefully be added similarly to last-action:
$ fgrep -A1 action /etc/setup/setup.rc
last-action
Download,Install
last-shortcut:
Desktop|StartMenu|none,...
This reminded me of a bug report I've been meaning to properly
characterise and report for a while, and also pointed me at a
workaround...
Currently, running `setup-*.exe --help` produces output that includes
the following:
-D --download Download packages from internet only
-L --local-install Install packages from local directory only
The default is to both download and install packages, unless either
--download or --local-install is specified.
I think the descriptions for the `-D` and `-L` options are misleading,
at least in combination with that final line, which is definitely wrong.
As I understand it, the actual behaviour would be better described by
something like the below:
-D --download Download packages from internet only, unless -L
is also specified
-L --local-install Install packages from local directory only,
unless -D is also specified
One could just remove the word 'only'?
If neither --download nor --local-install is specified, the default
is to repeat the same action as from the previous run. If no
previous run can be found, the default is to perform both actions,
and both actions can be explicitly requested by specifying both
--download and --local-install.

I think that makes the current help text accurately describe
non-interactive mode.
There are some cases in interactive mode which are obscure (e.g. '-M'
without '-D' or '-L' gets you whatever mode you used last time without
showing you what it was, but I'm not sure if that needs to be here.
In particular, the fact that the two options currently say they will
"only" do their action, and that the default is to perform both, lead me
to believe (a) the options were mutually exclusive and one would
presumably override the other, (b) this was probably a legacy from
before setup.rc stored the previous action, and therefore (c) if I was
running setup with `-q` or `-M`, there was no way to get the supposedly
default "do both" behaviour; I'd instead need to go through the full
GUI.
Having now seen how this setting is stored, I've realised I can just
call setup with `-DL` and it'll perform both actions again. But I think
my assumption that "default" was supposed to mean "default always" not
"default only on first run" wasn't *entirely* PEBCAK (even if it mostly
was), so that help text would definitely benefit from being made a bit
more explicit.
(I'm aware my suggestion above is decidedly wordy; it's not intended to
be exactly what I think is required, only a first pass at clarifying the
key details I think are missing.)
Perhaps the best thing would be to have something like
'--mode={download, install, somebetterwordforboth}' and document '-D'
and '-L' as short aliases for forms of that (which makes the modality
clear).

That did the trick. My nsswitch.conf was the default (no lines; only comments), but everything works great now once I change it to group: files Seems odd that changing it back to 'group: files db' causes the groups to revert to the Unix_Group+601 form (as if the files weren't resolving it satisfactorily).

That may be so, but in my installation, Samba reports the Unix User ID as owner, i. e. $ icacls server\\corinna\\foo \\server\corinna\foo S-1-22-1-500:(R,W,D,WDAC,WO) S-1-22-2-11125:(R) Everyone:(R) and that's with Samba 4.15.3.

These look like your standard Windows SIDs, so they are your SIDs for users cristina and croehrig on Windows. They should show up as such in ls -l output, unless the SID is actuall wrong, e. g., they map to your accounts on another machine or something like that. > On the windows client I have the same users and groups set up locally > (SAM) with appropriate SID mappings to the same uid/gids (601/603) in > the Cygwin /etc/passwd and /etc/group.

If you have matching /etc/passwd and /etc/group files, and your /etc/nsswitch.conf allows reading the files, this shouldn't happen. Are the Windows SIDs correct? Are they matching your machine?

Help with standalone samba SID-uid mapping
I'm trying to set up samba (standalone) following these instructions:
https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-samba
but I'm having no luck getting my samba user/groups to appear correctly using
the comment field as described in the document.
I'm using samba 4.13.14 on Ubuntu 20.04 with security = user (smbpasswd).
winbindd is not installed and I'm not using any LDAP or AD anywhere.
E.g. here is what is on the server (croehrig:croehrig = 601:601;
cristina:cristina = 603:603)
housesrv[3]% ls -l /House/Users
total 17
drwxr-xr-x 9 cristina cristina 22 Jan 12 16:06 cristina
drwxr-xr-x 30 croehrig croehrig 53 Jan 13 09:47 croehrig
Here are the ACLs and SIDs when looking on the windows client:
tyto[5]% icacls housesrv\\Users\\\*
\\housesrv\Users\cristina S-1-5-21-751087815-2087572193-42305691-1001:(F)
S-1-22-2-603:(RX)
Everyone:(RX)
\\housesrv\Users\croehrig S-1-5-21-751087815-2087572193-42305691-1000:(F)
S-1-22-2-601:(RX)
Everyone:(RX)
As you can see, the gid is mapping to the S-1-22-2- as described in the
document above, but
the uid is using a domain-specific SID with different RIDs.
On the windows client I have the same users and groups set up locally (SAM)
with appropriate SID mappings to the same uid/gids (601/603) in the Cygwin
/etc/passwd and /etc/group. This has all been working well to ensure e.g.
rsync preserves permissions and ownership between cygwin and Linux. (The
windows groups are called 'grp-croehrig' and 'grp-cristina' since windows users
and groups share a namespace, but they are mapped to 'croehrig' and 'cristina'
in /etc/group).
Here is how the SMB share looks under Cygwin:
tyto[6]% ls -l //housesrv/Users/
total 0
drwxr-xr-x 1 Unknown+User Unix_Group+603 0 Jan 12 16:06 cristina
drwxr-xr-x 1 Unknown+User Unix_Group+601 0 Jan 13 09:47 croehrig
tyto[7]% ls -ln //housesrv/Users/
total 0
drwxr-xr-x 1 4294967295 4278190683 0 Jan 12 16:06 cristina
drwxr-xr-x 1 4294967295 4278190681 0 Jan 13 09:47 croehrig
I have added the SAM desc/comment field as described in the document above:
i.e.
net localgroup grp-croehrig /comment:''
net user croehrig /comment:''
and restarted all Cygwin processes, but it doesn't seem to have any effect
('net user croehrig' shows the comment is indeed present). I guess I don't
understand how that comment field works.
Anyone have any advice?
Thanks,
-- Chris

w3m displays blank help page
I recently installed the w3m package. When I tried to display the
help page by typing "H", I got only a blank page with this message
in the status line:
≪ ↑ ↓ Viewing No Line
I did some poking around, ran w3m with strace, and found that w3m
runs the script /usr/libexec/w3m/cgi-bin/w3mhelp.cgi to generate its
help page. When I ran that script alone, I got this message (on one
line):
Can't use 'defined(%hash)' (Maybe you should just omit the defined()?) at
/usr/libexec/w3m/cgi-bin/w3mhelp.cgi line 51.
I did that, as shown in this diff:
$ diff w3mhelp.cgi.orig w3mhelp.cgi
51,53c51
< if (defined(%funcdesc)) {
< $lang = $tlang;
< }
---
> $lang = $tlang;
>
Having done that, the "H" help function works fine. So, I have
a workaround for the problem, but I'd really like a proper fix, and
there may be other users with this problem.
I also recently installed w3m onto my Ubuntu 20.04.3 LTS system and
the w3m help page displays fine there with no modification to that
file.
To see the problem:
1. At the bash prompt, execute
$ w3m -v
2. Type
H
The package appears to be installed properly:
$ cygcheck -c w3m

w3m 0.5.3-3OK
The output of "cygcheck -s -v -r", sanitized, is attached.

I'd appreciate any insight into the prunepaths option for the test

directory paths with "OneDrive" in them, and these three are the
most numerous:
5. /cygdrive/c/Users/corporatedroid/OneDrive - FoobarCorp/
6. /home/c_users_corporatedroid/corporatedroid/OneDrive - FoobarCorp/
7. /cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/FoobarCorp/
8. With the one-liner below, we create a small locatedb file

13. Here, we see that the path ending with 'ListSync'
incorrectly appears in the /var/locatedb_prune_test output despite the
prunepaths option in line 10:

Help with the prunepaths option with findutils updatedb locate
Fellow Cygwin fans,
I'm trying to keep the many directories with "OneDrive" in the
pathname out of the locatedb file, as I don't care to see them in
locate's output, nor bloat the locatedb file.
I'd appreciate any insight into the prunepaths option for the test
case below, (Line 10,) and how to tell prunepaths to ignore paths with
spaces so that the paths in Lines 5 and 6 below will not be included
in the locatedb file.
1. Versions:
2. updatedb (GNU findutils) 4.8.0
3. CYGWIN_NT-10.0 3.2.0(0.340/5/3) 2021-03-29 08:42 x86_64 Cygwin
4. Unfortunately, on this Windows 10 PC there are 650 unique
directory paths with "OneDrive" in them, and these three are the most
numerous:
5. /cygdrive/c/Users/corporatedroid/OneDrive - FoobarCorp/
6.
/home/c_users_corporatedroid/corporatedroid/OneDrive - FoobarCorp/
7.
/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/FoobarCorp/
8. With the one-liner below, we create a small locatedb file
(/var/locatedb_prune_test) and specify that prunepaths omit the
'/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive/ListSync'
subdirectory:
9. ==
10. F=/var/locatedb_prune_test; echo ; updatedb
--localpaths='/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive'
--output=${F}
--prunepaths='/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive/ListSync'
; ls -l ${F}
11. -rw-r--r-- 1 corporatedroid Domain Users 26280 Dec
9 06:22 /var/locatedb_prune_test
12. ==
13. Here, we see that the path ending with 'ListSync'
incorrectly appears in the /var/locatedb_prune_test output despite the
prunepaths option in line 10:
14. ==
15. F=/var/locatedb_prune_test;locate -d${F} 'ListSync'|cat -n|tail -3
16. 33
/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive/logs/ListSync/Business1/Nucleus-2021-12-09.1317.15440.1.odl
17. 34
/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive/logs/ListSync/Business1/microsoftNucleusTelemetryCache.otc
18. 35
/cygdrive/c/Users/corporatedroid/AppData/Local/Microsoft/OneDrive/logs/ListSync/Business1/telemetry-dll-ramp-value.txt
19. ==
Any ideas appreciated.

The data file you attached doesn't have "\r\n" line endings:
$ file rpcg_FF_filtrd.txt
rpcg_FF_filtrd.txt: ASCII text
compare with one that does:
$ file test.txt
test.txt: ASCII text, with CRLF line terminators

I don't use RS and start my awk scripts off with
sub("\r$", "", $0) # fix any \r\n line endings
so my scripts work with either flavor of line endings.
If you don't want to change your script try changing your input
unix2dos

Help using Cygwin on AppVeyor by Apache thrift, any lucky guesses?
Dear Cygwin community, I know that my report here is not super helpful, but I'm in a slightly tight spot, and hope that someone can help me with a lucky guess?! I'd like to improve the AppVeyor CI build for the Apache thrift project for Cygwin. Apache thrift builds and tests on Cygwin by default, but since a while, the builds have failed with cmake problems. The error message is not too helpful - so I hope that someone here may just have had the same issue before and can help? We use `apt-cyg` to install the packages, could this be related? Here is a link to a failed build log: https://ci.appveyor.com/project/ApacheSoftwareFoundation/thrift/builds/40263513/job/a69xt6m4o0y9x1bw?fullLog=true cmake fails with the (not so helpful) error message: C:/cygwin64/bin/cmake.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory The corresponding Cygwin AppVeyor installation is: https://github.com/apache/thrift/blob/781143e75cb585c0a88dea3f904c77228531d1d6/build/appveyor/CYGW-appveyor-install.bat After the install, there is a call to `refreshenv` in the appveyor.yml, so I think the problem is not due to an incomplete environment setup. And the corresponding Cygwin AppVeyor build script is: https://github.com/apache/thrift/blob/781143e75cb585c0a88dea3f904c77228531d1d6/build/appveyor/CYGW-appveyor-build.bat Any help would be highly appreciated!

Fix to help novice users verify cygwin.com downloads
Hey I was searching for some articles about verifying files today and I came across this page: Cygwin FAQ (http://www.cygwin.com/faq.html) on your site. I noticed you recommend very thorough verification, using hashes and sigs. But usually the data file is downloaded much more than the hash or sig files. Users often don't verify. Just wanted to give you a heads up that we created a free open source program that both downloads and verifies in one step. So your users always verify. It's like "Cygwin FAQ", but it's a single command that downloads and verifies thoroughly: https://denova.com/open/safeget/developer/ Might be worth a mention on your page. Either way, keep up the awesome work! Cheers, Bob P.S. The best way to make sure downloaders verify files is to give them one command that downloads and verifies in one step. There's a free open source solution. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

There were compatibility issues, most struggles came from Emacs dependency on external utilities to be fully functional (like search across files). Cygwin environment gave those utilities. Later in 2016 I had to work with Windows again and I discovered: https://cygwin.com/packages/summary/emacs-w32.html This package provides emacs binaries that use the native Windows GUI for display. Hooray! Good bye "cygwin-mount.el"! I maintain "e" command to open everything in Emacs: http://hg.defun.work/utils/file/tip/emacs It simplifies jump from Windows CLI to Cygwin Emacs. And recently Gradle 5.2 fixed escape sequence handling in Mintty, making it great again: https://docs.gradle.org/5.2/release-notes.html Gradle now detects when it is running from Mintty on Windows and enables the rich console. Mintty is a popular terminal emulator used by projects such as Cygwin and Git for Windows. > I was just indicating that (provided DISPLAY=:0.0 is set, as you pointed out) > WSL X apps play fine > with the Cygwin X server. > OK. No problem. I was surprised that you are using X Window from Cygwin for xterm + Emacs when there are stronger alternatives. At least you don't need to deal with env var DISPLAY. For "mintty" there is an issue with TERM=mintty which is not supported on most remote hosts. I fixed it in ~/.bashrc recently by: case $TERM in mintty*) alias ssh='TERM=xterm ssh' ;; esac Note that I need TERM=mintty for Gradle to work properly.

You are not allowed to edit them from the "Windows" process. Only from LXSS:

You'll face:
https://github.com/microsoft/WSL/issues/1524
changes made in Windows File System - not seen in Bash
Though I forgot about their announce of P9 fileserver (dated May 2019
Windows 10 version 1903):
> WSL hosts a new 9P fileserver, which exposes distro filesystems to Windows
> apps and tools via \\wsl$\\!
Details are here:
https://devblogs.microsoft.com/commandline/whats-new-for-wsl-in-windows-10-version-1903/
I tried in elevated cmd:
cmd# cd \\wsl$\debian\
'\\wsl$\debian\'
CMD does not support UNC paths as current directories.
cmd# net use x: \\wsl$\debian\
System error 67 has occurred.
The network name cannot be found.
It is only available in Explorer and some "cool" editors, like Code.
I do not know if Cygwin allows to "mount" that P9 fileserver...
There is an example of network mounting:
https://cygwin.com/cygwin-ug-net/mount.html
so I tried it:
bash# mount '//wsl$/debian' /mnt
mount: defaulting to 'notexec' mount option for speed since native path
references a remote share. Use '-f' option to override.
bash# ls /mnt
ls: cannot access '/mnt/initrd.img': Input/output error
ls: cannot access '/mnt/initrd.img.old': Input/output error
ls: cannot access '/mnt/vmlinuz': Input/output error
ls: cannot access '/mnt/vmlinuz.old': Input/output error
bin boot c d dev etc home init initrd.img initrd.img.old lib
lib64 media mnt opt proc root run sbin srv sys tmp usr
var vmlinuz vmlinuz.old
Cool! Let's make it permanent.
$ cat /etc/fstab
//wsl$/debian /wsl/debian ntfs binary,noacl,posix=0 0 0
//wsl$/ubuntu /wsl/ubuntu ntfs binary,noacl,posix=0 0 0
//wsl$/alpine /wsl/alpine ntfs binary,noacl,posix=0 0 0
$ mkdir -p /wsl/{ubuntu,debian,alpine}
$ mount /wsl/debian
$ mount /wsl/ubuntu
$ mount /wsl/wsl
And the final step it testing with Cygwin's Emacs W32:
I can read files, but on save I've got:
Saving file /wsl/debian/opt/sa-batch-am-dbsync/run.env...
basic-save-buffer-2: Unlocking file: Invalid argument,
/wsl/debian/opt/sa-batch-am-dbsync/run.env
Trying in Cygwin's bash:
bash# cd /wsl/debian/home/user/
bash# touch test.txt
bash# ls -l test.txt
-rw-r--r-- 1 user user 0 2020-11-26 21:18 test.txt
bash# echo 123 >test.txt
bash# echo 456 >>test.txt
bash# cat test.txt
123
456
So Emacs tries to make some "smart" locking on dumb FS... Need to
waste another few hours to make Emacs work.
At least I have something!

Help with setting Cygwin's Emacs W32 TRAMP to WSL 1
I'm using Cygwin for two reasons: mintty + Emacs w32.
Nowadays WSL 1 has become important (vendors provide ready to work
.deb packages,
I use: Ansible + Google Cloud SDK, if name any).
Still WSL 1 lacks UI and integrates less smoothly into my workflow
to replace Cygwin's amazing Emacs W32.
WSL1 files are "hidden" for regular access.
Emacs has TRAMP mode to access foreign environments:
https://www.gnu.org/software/tramp/
I tried to define configuration that should have allowed to access WSL 1
from Cygwin's Emacs via "wsl sh" jump (the way TRAMP support "su" &
"sudo" jumps):
*
https://www.reddit.com/r/emacs/comments/jrkgmy/tramp_for_wsl_1_from_cygwin_emacsw32/
* https://github.com/microsoft/WSL/issues/6236
- wsl.exe periodically sends control characters making impossible "piping"
via interactive/terminal mode
The problem is that when Cygwin's Emacs invokes "wsl.exe" conhost or
wsl?? thinks
it is in a PTY mode and sends different "clearing" terminal escape
sequences (see WSL issue report).
I reproduce garbage with Elisp code:
(setq xxx (make-process :name "xxx" :buffer "xxx" :command '("wsl"
"echo" "OK") :connection-type 'pty))
(stop-process xxx)
Note that changing the last argument "pty" => "pipe" solves the problem,
but things are a bit complicated...
TRAMP mode has been implemented via call to "sh" by internal API "make-process".
And then TRAMP sends "wsl ..." to the shell so WSL thinks it is in
PTY and I have no way
to influence that decision ((
I tried stupid tricks like passing everything related to "ws.exe" via
pipe to "cat":
(with-eval-after-load 'tramp
(setf (alist-get "wsl" tramp-methods nil nil #'equal)
'((tramp-login-program "sh")
(tramp-login-args (("-c") ("wsl") ("-u" "%u") ("-d" "%h")
("|" "cat")))
(tramp-remote-shell "/bin/sh")
(tramp-remote-shell-login ("-l"))
(tramp-remote-shell-args ("-c"))
(tramp-connection-timeout 10)
(tramp-session-timeout 300
or define a wrapper script that has "wsl ... | cat" inside. Nothing helped.
Few experiments with Cygwin's Expect also failed as I forgot
everything about that obscure tech...
So I need to write some wrapper that will bidirectionally pipe to "wsl.exe"
putting wsl into piped instead TTY mode.
It can be that there is a ready solution.
If not please advise which API should I use to write such a wrapper.
Should it be Cygwin's pipe/dup2/fork/execvp or popen?
Or should it be Windows native CreateChildProcess / WriteToPipe /
ReadFromPipe as here:
https://docs.microsoft.com/en-us/windows/win32/procthread/creating-a-child-process-with-redirected-input-and-output
Please CC me in replies, I'll check the mail archive after a week to
not lose any responses.

Hello. I've got a project where I'm using Cygwin's emacs + GNU Make + VC++. For some reason, it seems CL.exe colorizes or decorates its output and Emacs does not understand this, so what I get is a lot of control codes (e.g. things like "^[[?25l Creatin^[[?25h^[[?25l") which make the output very hard to read.

Hi Caba, I know qemu-system-i386 because the official binary is that size.As for the command used I use this:x86_64-w64-mingw32- this way it compiles perfectly except for the file sizes, if I add the option - s the error Bash option -s unknown, I use 64-bit El dom., 24 may. 2020 11:32, Csaba Ráduly via Cygwin escribió: > > Hi Juan Carlos, > > On 24/05/2020 02:08, Juan carlos Rebate via Cygwin wrote: > ... > > > 1 the compiler is extremely slow, gcc on Linux is about 10 times > > faster, How could I speed up the compilation process?. > > Unfortunately, Cygwin's emulation of fork() is slow compared to the native > Linux > implementation (I've seen 1000x difference once, in a test launching the > same > program repeatedly).

Unfortunately, Cygwin's emulation of fork() is slow compared to the native Linux implementation (I've seen 1000x difference once, in a test launching the same program repeatedly). There's not much you can do about it, except getting faster hardware. A C++ build involves lots and lots of programs being forked. 2 the executables produced are too fat, for example qemu-system-i386 is 65 MB, but it should be 10.5 MB, if I use the -s option in configure returns an unknown error message, how could I fix it? Thank you Why do you think qemu-system-i386 "should be 10.5 MB" ? Are you using 32-bit or 64-bit Cygwin? 64-bit executables are usually bigger than their 32-bit counterparts (although rarely six times as big). You really need to give us more information if you hope to get help, like the actual commands you used and the exact error message. Without those, we can only guess, and my crystal ball is not very reliable. If you want to strip the resulting executables, you could try setting the LDFLAGS environment variable to '-s' before running configure Csaba -- You can get very substantial performance improvements by not doing the right thing. - Scott Meyers, An Effective C++11/14 Sampler So if you're looking for a completely portable, 100% standards-conformat way to get the wrong information: this is what you want. - Scott Meyers (C++TDaWYK) -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
help compilation qemu
Good morning, in a previous post I was debating with some nice users (for technical reasons I can't retrieve that thread)The point is that although the qemu wiki says it can't compile with cygwin for 64-bit it actually can, and for technical reasons I haven't been able to communicate it before,The case is that making a couple of adjustments when looking for all the mingw packages if they can be found, but there is a problem,Well, really two problems.1 the compiler is extremely slow, gcc on Linux is about 10 times faster, How could I speed up the compilation process?. 2 the executables produced are too fat, for example qemu-system-i386 is 65 MB, but it should be 10.5 MB, if I use the -s option in configure returns an unknown error message, how could I fix it?

I tried to verify that, so I did [1a] On a cygwin prompt echo $PATH | grep -i msys [1b] On a msys prompt echo $PATH | grep -i cyg And got no conflicting results. (msys is not in the cygwin path, and cygwin is not in the msys path). [2] 'mount' only showed cygdrive on a cygwin prompt, and only msys on a msys prompt [3] Looked for a 'msys' string in a random binary in the path: [3a] On a msys prompt: strings `which ls.exe` | grep -i msys gave me msys hits. [3b] on a cygwin prompt: strings `which ls.exe` | grep -i msys gave me no hits. So it at least appears to me that the environments are not conflicting for me personally. Of course, that could very well be the case for the error results of the original poster. PS: if anyone knows of better tests/checks to see if the environments are intermingled in some way, I'd love to hear it. - Maarten -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

I just installed MSYS2 and followed the instructions provided in the QEMU wiki for MSYS2, and all preparatory steps of running msys2/pacman/git/configure (only excluding the actual 'make' for compilation) work as expected. There must be a difference between our setups/steps/configurations if that doesn't work for you. I can imagine issues with both MSYS and Cygwin installed, if the order of things on paths is not right, e.g., getting the Cygwin version of something when trying to run MSYS, or vice versa. Maybe try to make sure, when building qemu under MSYS, that no Cygwin things are in your path?
