[gentoo-user] openwatcom ebuild question
As background, http://bugs.gentoo.org/show_bug.cgi?id=233097 has an
experimental, unsupported ebuild for openwatcom-1.7.1 and it doesn't
quite work :-
The ebuild's src_compile function is:
src_compile() {
./build.sh || die build.sh failed
}
When I run emerge =dev-lang/openwatcom-1.7.1, the build fails with
/usr/lib/gcc/i686-pc-linux-gnu/4.1.2/../../../../i686-pc-linux-gnu/bin/ld:
i386:x86-64 architecture of input file `bootstrp/clibext.o' is
incompatible with i386 output distcc[16016] ERROR: compile (null)
on localhost failed
The full output of the emerge command is in the attached file.
Alternatively, I can manually unpack and build with commands:
ebuild =dev-lang/openwatcom-1.7.1.ebuild unpack
cd /var/tmp/dev-lang/openwatcom-1.7.1/work
./build.sh
With the steps performed manually, the compilation works properly.
Anybody familiar with the i386:x86-64 ... incompatible ... i386
message and know what it means?
Any suggestions on ebuild changes to correct this behavior?
Thanks !

You use distcc. But seems to be not well configured. Just disable
distcc to build the package (FEATURES=-distcc in /etc/make.conf).
HTH.
Xavier,
It helps a lot! I had installed distcc, but never quite got it
working. Getting it working is on my TODO list, but I hadn't thought
of it when the problem occurred.
Thanks!

Okay, this is not a distcc problem.
From looking at the bug. Do you really think by just tricking the
architecture check to accept x86_64 will make it magically compile.
You can't be serious! This software does not build on x86_64 at the
moment. If you don't have the appropriate programming skills to fix
this yourself you have to wait for the openwatcom developers to make
it x86_64 ready.

Daniel,
A detail I meant to include in my original posting is that I'm
attempting the build on (and for) a 32 bit machine. So distcc _is_
the problem.
The lack of 64-bit buildability for openwatcom is a whole 'nother
subject and I'm in communication with the developer about it.
Regards,
David

I used to work for the local Sybase reseller. I would not have thought management would ever have open-sourced anything. Well, well, whaddayaknow. Miracles do happen. watcom was a very nice compiler back in the day. I remember it trashing the pants off anything else in the market (this was in the DOS-3.x era) For more on Watcom C's history, including the Sybase release as open source, see http://www.openwatcom.org/index.php/History I used Watcom C quite a bit in the mid '90s to develop a bookkeepping program for Michigan Bingo games, and even made some spending money off of the project :- At that time, my host operating system was 32-bit OS/2 and the target was 16-bit DOS. Watcom worked like a champion for me!

This is what would happen if you temporarily told the system to allow
the installation of ~arch packages. Temporarily setting ~arch is a
Bad Idea!
I need to get an up-to-date version of eclipse working on my gentoo
box. First question is, is there a Galileo (3.5+) version of
eclipse available as a portage package? I can't find it, so I'd
really appreciate a pointer. The only thing I can see is a fairly
old eclipse version (I think a year or more out of date).
That is because the newer version is keyworded with ~arch. Emerge
will not tell you that there is a newer, keyworded version available.
Second question, at the eclipse website, I see a binary version of
the latest Linux-eclipse (the version I'm after). If I *can't* get
a portage package version of Galileo-eclipse,
Don't worry, I'll show you how in a little bit!
then if I install the binary package (non-portage)
from the eclipse website, can I get (and how can I get) portage to
consider this package as supplying any dependency which would be
otherwise supplied by the latest (ganymede, 3.4+) portage version
of the eclipse tool
As far as I know of, that is not possible without ugly hacks.
Unless I'm completely misreading your stuff, your examples tell me
how to install the (too old) portage version, which is in all cases
just too old for me, so my 2 questions boil down to (1) must I?,
and (2) How do I?
I don't know what you mean by must I?, but the answer to How do
I? is right here:
First, you need to create a folder called /etc/portage as root. Then,
create a file called package.keywords in that directory. When you
want to install a keyworded package (dev-java/eclipse-ecj-3.5.1 in
this case), you run
ACCEPT_KEYWORDS=~x86 emerge -pv eclipse-ecj
to see what packages are needed for the keyworded version. Then, you
copy the the package names mentioned to package.keywords. In the
example above, the command outputted:
[ebuild N] dev-python/pyxml-0.8.4-r2 USE=-doc -examples 0 kB
[ebuild N] dev-java/javatoolkit-0.3.0-r3 17 kB
[ebuild N] dev-java/ant-core-1.7.1-r4 USE=-doc -source 6,828
kB [ebuild N] app-admin/eselect-ecj-0.3 0 kB
[ebuild N] dev-java/eclipse-ecj-3.5.1 USE=ant 1,268 kB
[ebuild N] dev-java/ant-eclipse-ecj-3.5.1 0 kB
So you would add this:
dev-python/pyxml-0.8.4-r2
dev-java/javatoolkit-0.3.0-r3
dev-java/ant-core-1.7.1-r4
app-admin/eselect-ecj-0.3
dev-java/eclipse-ecj-3.5.1
dev-java/ant-eclipse-ecj-3.5.1
to the package.keywords file (note that this will probably be
different for your system, you should run the command yourself and
use that output to find out what you should put in the file). I would
also put a note above the lines to say why and when they were added,
in case I forget.

Good God. I hope you don't do that more than once a decade. Just how long can a life be? Unless he changes hardware while it is shutdown. I don't think the drivers have ever changed on my system since I built it. I have had to add a couple, ethernet card and a SATA card, but other than that, it should be the same.

[gentoo-user] Looking for x86 or AMD64 disassembler
G'day, I'm looking for a disassembler so that I can see the underlying assembly code in a variety of files, for example elf executables, DOS executables, binary files (such as the master boot record (MBR)), etc. Portage doesn't seem to include any, leastways eix hasn't revealed any to me. Searching google for disassemblers, I find a variety exist, but I haven't yet encountered any with ebuilds. If needs be, I can build direct from source or create a wrapper ebuild for the build. What do you all recommend for disassemblers? Are there any good ones for Gentoo? Regards, David

Are there any good ones for Gentoo? I've used objdump (part of binutils) in the past for looking at ELF files; look at the -d option for disassembly. A quick test shows that it seems to work for exe files too, but I've never used it that way as I don't use Windows much, so I don't know for sure. For the MBR, I don't know of any disassemblers per-se, but hex editors work well depending on what you are doing. hexdump (part of sys-apps/util-linux) works well. You might want to make an image of the MBR first with dd, depending on which tool you use, as some do not support reading from the disk directly. Regards, Brandon Vargo Hi Brandon, Indeed, hexdump mbr would show me the bytes but I want to see the code as instructions. objdump works fine for ELF. Being greedy, the ideal tool would handle all 3 formats. The immediate need is pure binary (like the MBR). A couple of weeks ago I had to resort to an old DOS disassembler for a DOS executable. I'd be much happier with a straight Linux solution. Regards, David
[gentoo-user] serial port identification question

Also note the S is capitol as well. Dale :-) :-) My /dev/tty* didn't include any /dev/ttyS* entries. Searching the web, I learned that MAKEDEV /dev/ttyS0 and MAKEDEV /dev/ttyS1 will create the missing entries and that stty -F /dev/ttyS0 -a will provide configuration information for the port. My little Serial.cpp class is now successfully writing to the port (as proved by my son running Hyperterminal and receiving the sent characters). However, receiving characters isn't yet working. Neither his hyperterminal nor my sender (with a loopback plug) is receiving.

Re: [gentoo-user] Re: serial port identification question
Hello James, Thanks for writing. Lots of good information in your post! I've working on porting some DOS code to Linux and (as you likely know) the code needed for serial communications differs greatly between the 2 environments. The initial problem was trying to identify COM1, COM2, etc from lots of /dev/tty?? entries. There were no /dev/ttyS? entries. This was solved thru googling and running MAKEDEV (for COM1, COM2, etc). The second problem seems to be an odd pinout. The device has an RJ11 connector and came with an RJ11 to RS232 cable. The DB9 connector is documented as TX on pin 2 and RX on pin 3 (which is normal). Connecting a breakout box, indicated TX on pin 3. With a null-modem and a loopback plug, send/receive started working using my program. Send/receive was also verified using 2 terminal sessions and commands: cat /dev/ttyS0 echo this is a test /dev/ttyS0 The tip on setserial is appreciated. I learned of stty's -F ... -a options, but didn't know of setserial. Having solved/learned the above on the Gentoo box, the next trick is getting my code to work on the embedded 486SX linux system (non-Gentoo). So far I know that programmed setting of baud rate is working (as confirmed with stty). However no data is being seen from the keypad or the two connected preamps. They should all be continuously sending data to com3, com2, and com4 (respectively). The programming world is full of strange and wonderful problems to solve, isn't it? Regards, David

In addition to that there was only 1 statistics message from syslog-ng. Anybody know what a --- MARK --- message mean?? Regards, David P.S. The machine is an AMD64 running 2.6.28-gentoo-r5. Overnight, VirtualBox was running (though in an idle state) and (probably) BackupPC was also running. Other than those 2 processes, nothing of significance was running, AFAIK.

It's just your syslog popping in occasionally and saying Hey, I'm still alive! Notice that it occurs (almost) exactly every 20 minutes. Kind of like syslog saying nobody told me to log anything, so I'll log something to show I (at the least) am still OK. So you probably need to look elsewhere to diagnose your problem. I suspect some sort of interaction between the 2 known/suspected heavy users -- VirtualBox and BackupPC. Guess it's time for a monitor to snapshot system status every 5 minutes so that if/when the problem occurs again, there's some info to look at.
[gentoo-user] VirtualBox, Gentoo, and USB thumb drives
I've been using VirtualBox recently with 32-bit Ubuntu for a work project.

[gentoo-user] baselayout2/openrc question
G'day, I've been running baselayout-2 for several months and it's been working fine AFAICT. Over the weekend I noticed that my USB thumb drive is no longer automounting. This evening I ran /etc/init.d/udev status which reported: * status: stopped. Running /etc/init.d/udev start reported: * The udev init-script is written for baselayout-2! * Please do not use it with baselayout-1!. * ERROR: udev failed to start The message occurs because /etc/init.d/udev checks for /etc/init.d/sysfs, which is not present. Googling indicates that /etc/init.d/sysf comes from sys-apps/openrc. I have openrc-0.3.0-r1 installed (from long ago). openrc-0.6.0-r1 is available, though keyworded ~amd64. Unmasking it and running emerge -p ... shows that sysvinit is a blocker. Is it safe to delete sysvinit and emerge openrc-0.6.0-r1? Am I likely to get myself into troubleif I do this? If so, how much and how deep? Regards, David

If so, how much and how deep? very very very very deep trouble if you restart the machine and everything is not complete yet. Do not do that. all version of baselayout-2 are marked unstable and you likely have an old version of sysvinit that is not compatible with the ancient openrc you do have. That openrc is not in portage anymore. You should upgrade to the latest unstable portage (which supports automatically resolving blockers). You need baselayout, openrc and sysvinit as well as /etc/init.d/sysfs. I have none of these in world yet all are present. With the latest portage, try again and let portage figure out for itself what it wants to do. Hi Alan, Reply appreciated! I've been running unstable versions of portage for many months and currently have 2.1.7.17, which _is_ the newest non-masked version. With it, sysvinit is blocking (capital B) openrc-0.6.0-r1 and /etc/init.d/sysfs is not present (which makes /etc/init.d/udev unhappy). Since /etc/init.d/udev only _checks_ for the presence of /etc/init.d/sysfs but doesn't run it (or anything), would creating a dummy (zero length) sysfs file be workable? Regards, David
[gentoo-user] trouble starting bash

Do you still have a process running named gnome-display-properties even after you close the Display preferences dialog box? Interesting question, but it's too late for me to answer it. While googling the subject I learned that the ATI driver (or some of its revisions) only check monitor type upon startup. I restarted X with ctl-alt-backspace and the extra box went away. gnome-display-properties _still_ says unknown, but the annoying box is gone.

Re: [gentoo-user] Re: Java problem
Walt and Kenneth,
Your help with this problem is appreciated, though the problem still
persists.
What versions of java do you guys have installed? What does eselect
java-vm list show on your machines?
I'm on AMD64, what architectures are you running?
Looking around, /usr/bin/java is a symlink to run-java-tool which is
working. For example java -version displays an appropriate value.
Output from multiple tests of eselect, java-config, and emerge is
attached. To summarize the attachment:
/usr/lib/jvm reports icedtea6 and sun-jdk-1.6.0.20
eselect java-vm list shows sun-jdk as active
eix -e --nocolor ant-core shows ant-core installed
eselect java-vm set system 1 successfully changes to icedtea6
emerge -qv ant-junit fails because ant-junit isn't found
eselect java-vm set system 2 successfully changes to sun-jdk-1.6.0.20
emerge -qv ant-junit fails because ant-junit isn't found
notice that both icedtea6 and sun-jdk-1.6.0.20 have been tried and emerge
ant-junit fails with both
On a related note,
java-config -S only works for user 'root'. It doesn't work for an
individual user, e.g. 'relson'
eselect java-vm set allows system-wide setting of the vm and also has a
per-user option.
Also, eselect includes an unnecessary (but harmless) / in the sym-link, i.e.
eselect: current-system-vm - /usr/lib/jvm//icedtea6
java-config: current-system-vm - /usr/lib/jvm/icedtea6

Well, I've seen those error messages more than once. If I were
half-a-bottle more sober, I'm sure I could remember how I fixed
the problem.
Gentoo offers two (competing?) ways to specify the system-vm.
#eselect java-vm
Usage: eselect java-vm action options
Extra actions:
list List Available Virtual Machines
set Set a new system or user vm
show Show the current vm
#java-config
Usage: java-config [options]
-L, --list-available-vms
List available Java Virtual Machines
-S VM, --set-system-vm=VM
Set the default Java VM for the system
I seem to recall that the important things changed by these two
gizmos are some symlinks like, for example:
/etc/java-config-2/current-system-vm - /usr/lib/jvm//sun-jdk-1.6/
/usr/bin/java - run-java-tool
Maybe I can remember more details tomorrow.
/usr/lib/jvm has:
lrwxrwxrwx 1 root root 17 May 22 23:44 icedtea6 - /usr/lib/icedtea6
lrwxrwxrwx 1 root root 21 May 22 21:29 sun-jdk-1.6 - /opt/sun-jdk-1.6.0.20

The extra arch has been removed, but didn't help matters ... I don't know if the java ebuilds, eclasses and wrapper-scripts are wise enough to figure out the correct dependencies with such keywords. I could imagine some part might figure out the arch as x86, but then your system vm would be set to the x86_64 vm, i.e., no x86 system vm set ...

It makes writing take significantly longer and I have had a DOM go bad (become unusable). Admittedly, I don't know whether the DOM does wear-levelling and I don't know the underlying cause of the failure. In any case it was Not Good (tm) ...

Re: [gentoo-user] help with Persistent hard disk device names with udev
My udev rules use a combination of KERNEL, ATTRS(serial), and SYMLINK to
create named entries in /dev for my 2 USB hard drives.
With the following rules in /etc/udev/rules.d/10-local.rules:
KERNEL==sd*, ATTRS{serial}==FD...7264507, SYMLINK+=WD1
KERNEL==sd*, ATTRS{serial}==FD...7285643, SYMLINK+=WD2
Plugging them in results in /dev entries like:
brw-rw 1 root disk8, 32 Aug 21 13:55 sdc
lrwxrwxrwx 1 root root 3 Aug 21 13:55 WD1 - sdc
brw-rw 1 root disk8, 32 Aug 21 13:55 sdd
lrwxrwxrwx 1 root root 3 Aug 21 13:55 WD2 - sdd
And in /etc/fstab, I reference /dev/WD1 and /dev/WD2
HTH,

Alternatively you can leave it caching as normal and then issue the sync command when you're done doing your USB operations and it'll flush remaining data to the flash drive immediately. (I think unmount/eject will do this too.) That's what I usually do. Sync really, really slows down writes, at least for a solid state drive. I'm looking for a way to avoid that slowdown without the dangers of a user yanking a flash drive before the cache is completely written out.

[gentoo-user] emacs iso-8859-1
G'day, ISO-8859-1 uses byte values 0xC0 to 0xFF for European accented characters (amongst otherss). I have a binary file whose bytes have values 0xC0 to 0xFF. Emacs is presently displaying them as octal, i.e. \300\301\302\303 etc. How do I get emacs to display them as accented characters? set-language-environment gives me some of the capability I want, but not all because it isn't sticky. Ideally setting a mode (or a variable) in my .emacs would affect newly opened files and show the accents. Thanks, David
[gentoo-user] flash drive mounting is very slow
Mounting USB devices is very, very slow. This morning I inserted my
PNY memory stick at 10:18:22 but df didn't show it mounted until 3
minutes later at 10:21:05.
As background information, in /etc/udev/rules.d/10-local.rules is:
KERNEL==sd*1, ATTRS{manufacturer}==PNY, SYMLINK+=PNY,
RUN+=/bin/mount -a
and in /etc/fstab is:
/dev/PNY /mnt/pny vfat rw,nosuid,auto 0 0
The kernel messages in /var/log/messages for this period of time are in
the attached file (to avoid line wrapping by mail clients).
Any thoughts on why it takes so long and how I can speed up
recognition?
Ideas for enabling more messages (from udev, the kernel, etc) to see
what's happening would also be helpful.
TIA,
David

The PNY stick mentioned runs very nicely on a machine at work. The
environment there is Ubuntu (as guest OS) running in VMWare on
WinXP (as host OS). Automounting works very nicely.
The slowness is true of several USB sticks.

[gentoo-user] pmount question
G'day, My USB subsystem is working much better now (than it was this weekend). /etc/fstab had a reference to /dev/hdb which no my current kernel no longer supports. Removing this has improved flash drive mounting a whole lot! I've also modified /etc/udev/rules.d/10-local.rules to use pmount device label rather than mount -a. This is mounting flash drives in /media as desired: root@osage media # ls -l total 32 drwx-- 19 root plugdev 16384 Dec 31 1969 PNY drwx-- 3 root plugdev 16384 Dec 31 1969 SD_2G However (as can be seen above) the permissions are 700, which makes the drives unusable by members of the plugdev group. Alternatively, I can use pmount -u 007 device label to provide full access to the plugdev group. This seems awkward and inelegant. What's the right way to use pmount and set permissions?

G'day, I've got a problem with eix on my 32-bit system (but not on my 64-bit system). Some GLIBCXX_3.4.?? symbols are not being found. emerge -e world didn't correct the problem. Any suggestions?

Any time you use gcc-config to change the working version of gcc, the symlink to libstdc++.so will also be changed automatically to point at the matching library version. Nope. I only have gcc-4.5.3. Evidently symlink /usr/lib/libstdc++.so.6 didn't get updated when libstdc++.so.6.0.14 was built. FWIW, the machine has the following versions of libstdc++.so 6.0.14 - Jul 21 2012 ( in /usr/lib/gcc/.../4.5.3 ) 6.0.8 - May 15 2007 ( in /usr/lib ) 6.0.6 - Aug 3 2006 ( in /usr/lib ) Regards, David
[gentoo-user] SSH question
G'day, I've volunteered to do some data entry for my local bike club. This involves a java application (jar file) and a tunnel to a mysql server. I have detailed PuTTY configuration instructions but haven't yet succeeded in converting them to ssh options. The configuration options include: Seconds between keepalives -- 120 Don't start a shell or command Forwarded port: source port number - PORT Destionation: MACHINE.DOMAIN.COM Host - IP_Address Login - userid Password - pw Using ssh -N userid@IP_Address gives me a password prompt and no command prompt - both good. How do I specify the forwarded port? Thank you. David

How do I specify the forwarded port? If I understand correctly, with -L: ssh -L XX:machine2:YY user@machine1 This command will connect you to the machine1 host with user user, and any connection to the port XX to the machine you are running the ssh command from, will redirect the connection to the machine2 host in the YY port. If you want to forward a local port XX to a remote port YY then Canek's suggestion will do what you want, assuming that the correct remote application is listening on port YY. When you have more than one application this can soon become tedious. So, if you want to set up the remote machine as a SOCKS proxy so that any socks-ified applications on the local machine can connect to the remote SOCKS, then you can use: ssh -N -D user@machine1 For applications that do not have built in proxy capability you can use e.g. proxychains. HTH. -- Regards, Mick H'lo Mick and Carnek, The mention of XX and YY wasn't transparent, but a bit of experimentation gave a good connection. Using the terms in my original post, I now have the following working command: ssh -2 -N -L PORT:MACHINE.DOMAIN.COM:22 userid@IP_Address Just need to add an appropriate TCPKeepAlive and all will be good.

It could also be the same port as the one you use at your local host.

[gentoo-user] udev rules
Good morning! I have a Rosewill 75 in 1 card reader with slots for USB, SATA, SD, microSD, etc. udev recognizes USB devices and mounts them as /media/whatever. However, when SD and microSD cards are inserted, /var/log/messages doesn't report anything and the cards aren't mounted. Any suggestions where to look? what to fix?

Neither of them worked for long. I sent one back for repair/replacement and got a new one with about the same problem. I didn't send it back again because it wasn't worth shipping back again plus I was expecting it to work at least for a little while. It lasted overnight My new policy, don't buy Rosewill products. They may work fine for someone else but they don't for me. Dale Actually what I've got is a SanDisk 16GB microSD with an SD adapter. Using my wife's windoze laptop, the SD/microSD combo works fine. My initial use of the card is for Ubuntu linux for a MK802+ mini-pc. The MK802+ boots Android off its internal storage or Ubuntu off of the microSD. So, yes, the card appears to work. David
Re: [gentoo-user] Re: [OT] Questions about building from source tarball
In the past when I wanted/needed a newer version of a package than is in portage, I'd create an entry in /usr/local/portage. For example for app-example/some-package/some-package.x.y.z.ebuild, I'd 1) create directory /usr/local/portage/app-example/some-package 2) copy some-package.x.y.z.ebuild to some-package.x.y.z-r1.ebuild (in the new directory). 3) Some editing of the new ebuild might be needed here... 4) Run ebuild ... digest on the new ebuild to create the Manifest file. 5) test with ebuild ... compile or emerge some-package. 6) when errors are encountered, repeat steps 3, 4, and 5.

[gentoo-user] Xorg - RADEON vs VESA
Greetings, Last night I had to reboot my box because the screen had gone all wonky. The reboot has resulted in an obviously different font being used in terminal windows, emacs, etc, etc. Comparing Xorg logs from Oct (the previous reboot) to now, Xorg has been upgraded from 1.12.2 to 1.13.0. The logs are similar for approx 400 lines, then diverge. Below is shown the beginning of the log file differences. Any suggestions? Thanks.

I noticed this one or twice before. It is compiling the same
compiler version twice when it should be upgrading/recompiling two
*different* versions. I read before that gcc compiles three times
or something but the thing is, it can compile for HOURS and never
finish. Usually I stop it and restart emerge and it compiles as it
should, one for each version and finishes as it should time wise.
I once started the upgrade and went to take a nap. I woke up
around 5 or 6 hours later to find gcc compiling twice on the same
version. Even libreoffice only takes a hour or so.
Anyone else see this before? Now to go stop this one and get it to
update right and not take all week.
What have you got in world for gcc?
What's in make.conf?
gcc's build system does cause gcc tro be built three times[1], but
that's internal to gcc and has nothing to do with portage. There
should still only be one emerge for a SLOT. If it's doing the same
package twice, then the files in /var/tmp/portage are liable to get
continually clobbered and who knows what will happen.
[1] The logic goes something like this: it's a compiler, so the code
it produces must be consistently identical for identical inputs. So,
the current compiler builds gcc, giving version Y built by version X.
That instance of gcc in turn builds a gcc, giving version Y built by
version Y.
Haven't you left out the third compile?
Let me rephrase the 3 builds.
1) gcc-X builds gcc-Y giving gcc-Y1
2) gcc-Y1 builds gcc-Y giving gcc-Y2
3) gcc-Y2 builds gcc-Y giving gcc-Y3
gcc-Y1 and gcc-Y2 are likely to be different (since they were build by
gcc-X and gcc-Y which are likely to have optimizations).
gcc-Y2 and gcc-Y3 should be identical (since both were built by gcc-Y)
Now you should have two copies of the same version of gcc, and they
should be identical, plus the output code must also be identical. The
gcc builds system checks for this by actually doing compiles and
comparing the results. I've gotten a bit hazy on what specific bits
actually do what, but that's the general concept. But all this
rebuilding is internal and you only see it if you examine the console
output scrolling by, it will never show up in any portage tools.
