[fpc-other] How to modify install scripts when svn disappeared?
I have for many years now been using an install script to get the sources of fpc and lazarus via svn based on the specific tags. Then the script installs the needed dependencies and makes the complete installation on Raspberry Pi boxes. Now I have two problems: 1) The svn server seems to be down so the source retrieval does not work 2) I cannot find any tutorial on how to proceed with modifications of scripts to move from svn to gitlab. Please advice how to: 1) Find which is the latest release tag of fpc and lazarus 2) Retrieve the full sources for that tag on the command line As soon as I have the sources I believe the rest of my script will work just fine... The retrieval lines in my script read as follows: echo "Downloading version $FPCVER of FPC" cd "$FPCDIR" svn co https://svn.freepascal.org/svn/fpc/tags/$FPCTAG/ $FPCVER echo "Downloading version $LAZVER of Lazarus" cd "$LAZDIR" svn co https://svn.freepascal.org/svn/lazarus/tags/$LAZTAG/ $LAZVER What could I replace these svn calls with? I have not used git for anything else than to download a specific code base for a utility from github. All of my developing is versioned via subversion... -- Bo Berglund Developer in Sweden ___ fpc-other maillist - fpc-other@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other
Re: [fpc-other] GIT versioning server on Raspberry Pi?
Report on progress:
I have found a way to convert CVS to GIT using the cvs2svn module,
which contains a cvs2git file. It was described in this article:
https://devsector.wordpress.com/2014/05/17/migrate-cvs-to-git-with-cvs2svn/
Since our CVS server resides on Windows and is driven by CVSNT and the
conversion process (a Python system) uses the cvs executable to
extract revision information from the version files I decided to give
it a try on Windows7.
After some misunderstandings causing me to restart the conversions I
finally managed to convert some test projects.
But there is one very strange thing happening:
After the conversion is done according to the steps in the article
this happens when I run a check on the created GIT repo:
$ git status
On branch master
Changes to be committed:
(use "git reset HEAD ..." to unstage)
deleted:SSM1/ReadMe.txt
Why is the repo in this condition?
And what to do about it? Obviously going over it with
git reset HEAD ...
isn't really practical since this example project (an Android App)
contains deeply nested folder trees with hundreds of files.
I am worrying that I am doing this all wrong...
It is possible to clone the repo and get the expected file tree out,
though.
Another issue is that it seems like the conversion of a CVS repository
consisting of many different modules ("projects" if you will) ends up
with a single huge GIT repo which can only be cloned in its
entirety...
How can one store multiple and *separate* projects in GIT?

Re: [fpc-other] GIT versioning server on Raspberry Pi?
Continuing with GIT... I am now studying a few on-line documents outlining the conversion of a CVS repository to GIT. There is a script suite named cvs2svn with a number of specific scripts for various targets like cvs2git, so I think I can use this. But I think I have found a problem, which may or may not exist, but I need to check: We use the CVS modules concept a lot in our CVS repository. It virtualizes programming projects by collecting files from various "common" modules into a target structure for the project itself. We have as example a CommonFiles module, which contains 26 files implementing various commonly needed functions. In any given actual project the specific source files for that project is stored as a named module of files. Now the module definition in CVS collects the files and folders from various places into the structure of the project itself, often placing the files for the actual project into a "source" folder. The common files are placed in separate folders next to the source folder in the checkout. The net effect is that we have these specific and common files collected into folders in the work project folder ready to be worked on. The beauty of this is that we do not need to duplicate common functionality between projects as would be the case if we *copied* the common files into the source folder. These files are used in many places but versioned in a single place on the server. What would be the corresponding GIT method for this? Or is it even possible? -- Bo Berglund Developer in Sweden ___ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other

Is it possible to get the GIT sources without GIT? Stupid question by me... I should use git to get git sources *before* I uninstall the apt-get version of git. The solution is in page: https://git-scm.com/downloads as this command: git clone https://github.com/git/git I used it and it finished successfully in a rather short time. What I received is the latest *development* version, but if I got the idea behind GIT I should now have a git repo locally on my RPi3 and should be able to retrieve the latest released version of git from that, right? If so how do I move forward and find the release, update to it and then build and install git from the sources? The apt-get version of the git I use now is: ~/ $git --version git version 2.1.4 Seems a bit oldish so I updated the RPi3 according to the ProGIT book section 1.5: sudo apt-get install dh-autoreconf libcurl4-gnutls-dev libexpat1-dev gettext libz-dev libssl-dev Then tried to make as per the INSTALL file. Ran for some time and succeeded. So I then also got requirements for the other stuff: sudo apt-get install asciidoc xmlto docbook2x getopt But it failed with this error: E: Unable to locate package getopt so I removed getopt from the install and all other modules installed fine. Then I did: make configure ./configure make all doc info make install install-doc install-html install-info The last line failed as follows: $ make install install-doc install-html install-info SUBDIR git-gui SUBDIR gitk-git SUBDIR perl SUBDIR templates install -d -m 755 '/usr/local/bin' install: cannot change permissions of /usr/local/bin: Operation not permitted Makefile:2408: recipe for target 'install' failed make: *** [install] Error 1 Is it not påossible to put docs and info below the ~/ dir? According to the INSTALL file on the subject of Git install it says: Git installation Normally you can just do "make" followed by "make install", and that will install the git programs in your own ~/bin/ directory.

Re: [fpc-other] GIT versioning server on Raspberry Pi?
FPC ignore line ending differences? And lastly regarding CVS conversion: Since we have not used CVS in any complex way (but we do use the CVSNT flavour on Windows), I assume that the repository files would be possible to convert into the GIT format. After all each file contains a history with commit messages, timestamps, tags and branches, which are all OK. But the organization may well consitute a problem since we have several cases where multiple products (projects in GIT maybe) are sharing common code via CVS modules. So the same files are used in several places. They are stored outside project modules (folder hierarchies) and brought in at checkout time into subdirectories of the project source tree. Will that complicate GIT conversion? -- Bo Berglund Developer in Sweden ___ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other

[fpc-other] GIT versioning server on Raspberry Pi?
I have followed parts of the very long thread "GIT & SVN" and found it informative and partly amusing too... Since I am still on CVS it really was getting me to think about new version control systems and especially GIT since Graeme is pushing so hard for it. Background: --- I have a small company where the engineering team is myself (not so much anymore) and two engineers doing software and electronics. We are making embedded systems and PC (Windows) based processing software. Back in 2002 in order to safeguard against various catastrophies I put in place a CVS *server* on our network for managing the versions of our code and also our CAD drawings and documentation etc. So a lot of the files in CVS are binary. The instructions and firmware image files for our production people are also on our CVS. The CVS backend is an old CVSNT release on a Windows Server 2003 and we use the same cvsnt as client but via the WinCVS GUI front-end. Problems to solve: -- - We need to get a system that is supported today and preferably on a platform that will not be obsoleted like the Windows versions are. - Since we are also now doing development in Linux (for Raspberry Pi using FPC) we need something running on Linux (for the clients). - Generally I don't want us to be ancient tool-wise, but at the same time we have such a huge amount of information invested into the CVS repository. So I need the end soultion to hve some functionality like the CVS system we use today. And a possibility to import the CVS stuff. Testing So I thought that one way to go forward was for me to use an RPi3 box as a repository server with GIT or whatever (seems like the CVS successor SVN is now also on the decline...). Is there a good way to set up an RPi3 box as a GIT server and get going with that? Can GIT work in a way that would be comparable to CVS regarding concurrent development etc?

Which is exactly how a newsreader works too, you download the messages into the NR and then they are available offline forever and searchable too. My FPC message store reaches back to Sept 2003 and similarly for Borland/Embarcadero Delphi lists (might go even further back on these).

Re: [fpc-other] Networking problem from Linux virtual machine hosting Lazarus
I found cause of the problem! - It turns out that another connectivity configuration screwed up the connection from my virtual machine! Here goes: Some time ago I wanted to share my Win7 VPN connection to the Raspberry Pi target for my Lazarus development when I worked on the Pi. The reason is the same as for the Linux virtual machine: to reach the company software version control server on the internal company network. The only way I could figure this out was to set up my Win7 as a WiFi hotspot and configure the VPN channel as shared to the WiFi access point network. The sharing was configured on the VPN connectoid targeting the AP network. Then whenever the Pi connected to the WiFi AP served by my Win7 laptop it would get access to the VPN network. Since the Pi also had an Ethernet wired connection I had to set up the route for 10.0.0.0 on the Pi to target the wlan0 network rather than the eth0 network. For this I created a shellscript that runs by cron every minute and checks the connection status and route table. With this I could connect to the VPN network (10.0.0.x) from the Pi via WiFi and everything else via eth0. On the Win7 laptop I have a batch script that enables the WiFi access point when needed. So I believed that this would make the connection depend on my WiFi AP state. But it seems like the very fact that "Internet Sharing" is enabled on the VPN connectoid towards the Access Point network excludes it from everything else including the VMWare NAT network... As soon as I removed the Internet sharing setting on the VPN connection I could start pinging VPN from the Linux Mint virtual machine when VPN is connected. So now I have created a second copy of the VPN connectoid (different name) where the sharing towards the Access point is enabled. When I need the RPi to have access I connect to VPN using this connectoid and start the access point. Otherwise I have the AP shut down and the original VPN connection (without sharing) active, and now the virtual machine gets a route into VPN. Rather convolved but actually working. PS: I tried to share the VPN connection to the Ethernet network on my Win7 laptop. The plan was for the other computers on my network (RPi units as well as my wife's laptop) to get access via a route to my laptop for that network. However, that fell flat on its face because when I did that my Ethernet networking on the PC stopped working. Could not reach local resources on my internal network anymore....

[fpc-other] Networking problem from Linux virtual machine hosting Lazarus
I hope this might be acceptable to ask here even if it is FPC and Lazarus off topic I have created a VMWare WS12PRO virtual machine in which I have installed Linux Mint 17.3 MATE to host FreePascal 3.0.0 and Lazarus 1.6. These are now fine and working. As a last item I need to secure connectivity to the company version control system hosted on a Windows server on address 10.0.0.7 This network is on-line on the VMWare host PC (Windows7 X64) via VPN. I have set the virtual machine networking to NAT so it will use the host networking system and it should be able therefore to use the VPN channel to reach the 10.0.0.7 server. This is the addresses of my system: Main PC (VMWare host): IP=192.168.0.137 Mask=255.255.255.0 GW=192.168.0.129 VMWare virtual adapter for vnet8 on main PC: IP=192.168.80.1 Mask=255.255.255.0 Linux Mint virtual machine: IP=192.168.80.130 Mask=255.255.255.0 GW=192.168.80.2 Server on VPN network: IP=10.0.0.7 Mask=255.255.255.0 I know that this should work but I feel that there is something missing on the Linux side to make it actually start working... On previous Linux virtual machines (VMWare Workstation 7 level) I did not have to do anything else than connect VPN on my host PC to make that network also available on the virtual computer. Does not work now... I have tried adding route 10.0.0.0 on the linux side as follows: bosse@mint17mate ~ $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.80.2 0.0.0.0 UG0 0 0 eth0 10.0.0.0 192.168.80.1 255.255.255.0 UG0 0 0 eth0 192.168.80.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 But this does not work either. I don't get any ping response. On the host system I get immediate response... Is there anyone here who has done this and made it work? -- Bo Berglund Developer in Sweden ___ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other

Re: [fpc-other] [fpc-pascal] Access GPIO pins on RPi2 without root?
Thanks,
I have come a lot further now, in fact I am done with the basic reasearch on
how to do the I/O.
What I found is that the pigpio.pas file found in the lazarus wiki needs
some slight modifications
and then it is perfectly OK to use. No need for any bigger driver than this
to do the RPi2 I/O.
I have added a define for RPi2 and used it thus:
[code]
interface
// The following option controls whether the code is optimized for Raspberry
PI 2.
// Added 2015-10-10 by Bo Berglund following web advice to get it working on
the Pi2 hardware
{$DEFINE RPi2}
...
const
REG_GPIO = {$IFDEF RPi2} $3F000 {$ELSE} $2 {$ENDIF};//bcm2835/bcm2836
gpio register
...
// Mapping the RPi GPIO pin functions to GPIO I/O, should be here rather
than in user code
RPI_P3 = 2; //GPIO2
RPI_P5 = 3; //GPIO3
RPI_P7 = 4; //GPIO4
RPI_P8 = 14; //GPIO14
RPI_P10 = 15; //GPIO15
RPI_P11 = 17; //GPIO17
RPI_P12 = 18; //GPIO18
RPI_P13 = 27; //GPIO27
RPI_P15 = 22; //GPIO22
RPI_P16 = 23; //GPIO23
RPI_P18 = 24; //GPIO24
RPI_P19 = 10; //GPIO10
RPI_P21 = 9; //GPIO9
RPI_P22 = 25; //GPIO25
RPI_P23 = 11; //GPIO11
RPI_P24 = 8; //GPIO8
RPI_P26 = 7; //GPIO7
...
function TIoDriver.MapIo: boolean;
begin
Result := True;
{$IFDEF RPi2}
fd := fpopen('/dev/gpiomem', O_RdWr or O_Sync); // Open the master
/dev/memory device
{$ELSE}
fd := fpopen('/dev/mem', O_RdWr or O_Sync); // Open the master
/dev/memory device
{$ENDIF}
if fd < 0 then
begin
Result := False; // unsuccessful memory mapping
end;
//
end;
[/code]
With this in place the standard user pi will have access to the needed
/dev/gpiomem device and no root is required.
I have successfully used several ports to drive a relay board now.

Bo Berglund

You can add any user to any group you like, by using the groupadd program
in the terminal. For example,
usermod -a -G audio pi
would add the pi user to the audio group, allowing them to use audio
functions without having to be root or use sudo for the access.
Of course, the usermod command needs to be run as root, either with sudo,
or as being logged in as root
If you can figure out what group the io pins are in, this could solve your
problem.

Re: [fpc-other] [fpc-pascal] Access GPIO pins on RPi2 without root?
>If it would be a FPC specific usage question then it would be a bad idea to
post it to fpc-other.
>However as others have already stated accessing GPIOs on RPi is non
specific to FPC and thus it doesn't need to be on fpc-pascal or even
fpc-devel.
OK, I understand.
I have researched a bit more now given the input I received.
Apparently on a Raspberry Pi there are several defined user groups with
specific permissions on the /dev/xxx device files.
It seems like the user pi is member of a lot of these groups and thus would
not really need root to run a program accessing the hardware.
However, when I look at the unit pigpio.pas I found in the lazarus wiki
following a link in one of the responses I got I see this:
function TIoDriver.MapIo: boolean;
begin
Result := True;
fd := fpopen('/dev/mem', O_RdWr or O_Sync); // Open the master /dev/memory
device
if fd < 0 then
begin
Result := False; // unsuccessful memory mapping
end;
//
end;
Notice that the file used is /dev/mem
I don't know if there exists a user group named mem, but in any case the
user pi is not member of any such group.
Could this be the cause for root to be required?
pi@rpi2-jessie ~ $ groups pi
pi : pi adm dialout cdrom sudo audio video plugdev games users input netdev
spi i2c gpio
I asked a similar question in the Raspberry Pi forum and got a reply telling
me to modify this to become:
fd := fpopen('/dev/gpiomem', O_RdWr or O_Sync);
While writing this the final compile of lazarus just finished (I have
started from scratch using Raspbian Jessie and installed trunk of both fpc
and lazarus from svn).
So now I will soon be able to check this

Bo Berglund
