How to set up distccd symlinks

[keithspg]

I was running distccd and now it will not distribute after I ran this:
$this->bbcode_second_pass_code('', 'sudo update-distcc-symlinks')
Now the symlinks that used to be in /usr/lib/distccd which allowed me to cross compile are gone. How do I put them back?

You should not need to run that/the package ships them. Recommend you uninstall distcc, remove any custom symlinks you made and reinstall it.

Thanks for the help. When I build some of the arm packages from the RPi and try to distribute to the x86 machine, I get errors of 'file missing' and before I ran that script, it removed some links in that directory which were related to the cross tool packages.

I am building special packages for a custom image on all 3 RPi architectures (I am a glutton for punishment!) and trying to update all the needed packages to get my armv6 build system current with the armv7/aarch64 cross tools. I was finally able to get the cross tool to build for armv6, but keep getting 'failed to distribute' on some packages and others I get some file not found error. Consulting the google, it seemed that a sym link needed to be in that directory which is named the arm compiler but points to distcc. Is this incorrect?

Distcc can be tricky. If you goal is to have x86_64 help build ARM packages use https://aur.archlinux.org/packages/distccd-arch-arm on ARM and https://aur.archlinux.org/packages/distccd-alarm-armv8 on x86_64. There is also a toolchain for armv7h but not armv6h anymore.

Thanks for the help. Still reading through it and trying to understand.
I have a full v6 linux-rpi-legacy install running in a chroot to make sure I have all the associated libraries and dependencies for all of these packages. It is on a Pi4 and I can build many things, but the one I am truing to build now always comes back with:
$this->bbcode_second_pass_code('', 'distccd[897363] (dcc_execvp) ERROR: failed to exec c++: No such file or directory

Maybe I am misunderstanding, but I think it is looking for a c++ link in that /usr/lib/distcc directory and there is not one there which aligns with armv6:
$this->bbcode_second_pass_code('', '$ ls -al /usr/lib/distcc/

shouldn't there be some other sym links so that distccd knows they are valid?

So, I am set up a little differently. I have an armv7 host and have a complete armv6 image running in a chroot. I have been using this to build armv6 packages for a number of years until the armv6 updates freom arch arm stopped in February. In the meantime, I have been updating this image bit by bit as I have needed to to continue building specific packages for our purpose.
I have updated makepkg and gcc and many libs by taking the PKGBUILD and associated files form thje archARM and regular Arch Linux package information. I get the current file info from https://archlinux.org/packages/ and when a package does not build, I then build the missing pre-reqs and install then then try again. I was able to build gcc 12.2 and install it and the gcc libs for armv6 in the chroot

Currently, my biggest issue is that makepkg will not build llvm. It builds a binary, but then fails when building the tests then never makes the package. I need this package to build the latest mpd.

When I start it, I get lots of failed to distribute on the build image, and on the x86 machine I get lots of:
$this->bbcode_second_pass_code('', '/llvm-14.0.6.src/unittests/tools/llvm-exegesis/PowerPC/TargetTest.cpp

')

Do I need to build and install more libs and pre-reqs to get this to work?

[keithspg]

I was able to get it to work, again. I compiled xtools for armv6 and also makepkg for armv6 but used the old /etc/makepkg.conf file (When it compiles, it can no longer resolve the architecture type ), but after I did this and ran this script on the x86 machine
$this->bbcode_second_pass_code('', '#!/bin/bash
for file in `ls`; do
if [[ "$file" == "link" ]]; then
continue
fi
# uncomment for v6
ln -s $file ${file#arm-unknown-linux-gnueabihf-}
ln -s $file armv6l-unknown-linux-gnueabihf-${file#arm-unknown-linux-gnueabihf-}
done')
in
$this->bbcode_second_pass_code('', '/opt/x-tools6h/arm-unknown-linux-gnueabihf/bin/')
I now can get compilation, again using distccd. The messages all look like:
$this->bbcode_second_pass_code('', 'distccd[20392] (dcc_job_summary) client: 192.168.1.199:46430 COMPILE_OK exit:0 sig:0 core:0 ret:0 time:5243ms c++ /Rune_dev/armv6/llvm/src/llvm-14.0.6.src/lib/ExecutionEngine/Orc/Speculation.cpp')
in the log on the x86 machine. Woo Hoo!
