www-client/chromium failed to use distcc properly

Seeing this thread Speeding up complilation on Raspberry Pi 5 bare metal, decided to give it a try.
Surprisingly, it compiled:

Code: Select all

genlop -t chromium
 * www-client/chromium

     Tue Jul 29 11:11:26 2025 >>> www-client/chromium-138.0.7204.168
       merge time: 1 day, 8 hours, 20 minutes and 57 seconds.

The next step was to try to use distcc. Tried directly with llvm as chromium compile on gentoo using clang and the others packages can be compiled on pi5 itself, without help in under 24 hours. Didn't work:

Code: Select all

crossdev --llvm aarch64-unknown-linux-gnu

 * error: LLVM/Clang cannot currently compile glibc
 * 
 * If you file a bug, please attach the following logfiles:
 * /-info.log

So, I setup crossdev normaly, using gcc and distcc.
For clang setup the helper scripts:

Code: Select all

gentoo /usr/local/bin # cat aarch64-unknown-linux-gnu-clang*
#!/bin/sh
CHOST=aarch64-unknown-linux-gnu
/usr/lib/llvm/20/bin/clang --target=${CHOST} $@
#!/bin/sh
CHOST=aarch64-unknown-linux-gnu
/usr/lib/llvm/20/bin/clang++ --target=${CHOST} $@
#!/bin/sh
CHOST=aarch64-unknown-linux-gnu
/usr/lib/llvm/20/bin/clang++ --target=${CHOST} $@
#!/bin/sh
CHOST=aarch64-unknown-linux-gnu
/usr/lib/llvm/20/bin/clang --target=${CHOST} $@

The problem: Can not compile chromium using distcc. Others packages can be compiled with distcc by using either gcc or clang. Tried with app-misc/mc and libreoffice, with both gcc and clang.

What I'm doing wrong ?

costel78,

What I'm doing wrong ?

You did nothing wrong. But you may have misunderstand how 'distcc' work.

By design NOT every objects targeted by build system can be distributed to distcc helper for compilation. by default only C/C++ source code can be distribute to distcc helper.

In your case '../../tools/cfi/ignores.txt' in chromium build system was generate by 'bindgen' therefor distcc will not use it therefor distcc helper will fail. but this failure by distcc design are tolerated and the compile process shifted to use local compiler.

So in the end the build system continue without failure and therefor the build should eventually success.

First, thank you for your support!
The goal was to reduce at ~8 hours those 32 hours of compile. If distcc is not a solution, then I will keep using flatpak version.
Flatpak has a few disadvantages: ~3GB space required, six time more than chromium - dependencies included, a less portable config among others Raspberry Pi etc.
Well, a chromium compile per week is to much on Pi itself.
