Hi all,

I've *sometimes* encountered a build failure on gobject-introspection in
warrior 2.7.2.

Here is how to reproduce:

git clone git://git.yoctoproject.org/poky
cd poky
git checkout 109ef2e5c4161a2c0ac58bede3daa48c7b4881ec #for master I tested or warrior-21.0.2
source oe-init-build-env
echo 'ICECC_PATH = "/usr/bin/icecc"' >> conf/local.conf
echo 'INHERIT += "icecc"' >> conf/local.conf
while true; do (bitbake gobject-introspection -c cleansstate && bitbake gobject-introspection -c compile) || break ; done

Full log is attached, the interesting excerpt is here:

If the above error message is about missing .so libraries, then setting up GIR_EXTRA_LIBS_PATH in the recipe should help.
(typically like this: GIR_EXTRA_LIBS_PATH="${B}/something/.libs" )

This tells us pretty much nothing. It's not the only line, all next ones
are failing with the same cryptic error message.

So I replaced the ninja call in run.do_compile by that exact line above
and ran run.do_compile manually, the outcome is:
Error while loading /tmp/poky/build/tmp/work/core2-64-poky-linux/gobject-introspection/1.62.0-r0/build/tools/g-ir-compiler: No such file or directory
If the above error message is about missing .so libraries, then setting up GIR_EXTRA_LIBS_PATH in the recipe should help.
(typically like this: GIR_EXTRA_LIBS_PATH="${B}/something/.libs" )
WARNING: exit code 1 from a shell command.

And indeed, the file is not there and is there every time the
compilation works.

$ find /tmp/poky/build/tmp/work/core2-64-poky-linux/gobject-introspection/1.62.0-r0/ -name "*g-ir-compiler*"

Disabling ICECC for that recipe makes it work just fine.

1) Does anyone have any idea about what's happening?
2) Can we have the complete error message in log.do_compile instead of
the line "Error while loading /tmp/poky/build/tmp/work/core2-64-poky-linux/gobject-introspection/1.62.0-r0/build/tools/g-ir-compiler: No such file or directory"
missing?

FYI, I run Ubuntu 18.04.03 and most of the company is using that one or
16.04. I have icecc 1.1-2.
