Hello.
Please consider the attached patch (suggested by Sergei Trofimovich).
Explanation: In a failed build log, we can see this:
for tool in gnatbind gnatchop gnat gnatkr gnatlink gnatls gnatmake gnatname
gnatprep gnatclean ; do \
if [ -f $tool ] ; \
then \
mv $tool $tool-cross; \
fi; \
done
and later:
/bin/bash: line 1: ../../gnatbind: No such file or directory
make[6]: *** [../gcc-interface/Makefile:918: b_gnatm.adb] Error 127
make[6]: Leaving directory '/<<PKGBUILDDIR>>/gcc/build/gcc/ada/tools'
make[5]: *** [Makefile:210: gnattools-native] Error 2
make[5]: Leaving directory '/<<PKGBUILDDIR>>/gcc/build/gnattools'
make[4]: *** [Makefile:10700: all-gnattools] Error 2
make[4]: Leaving directory '/<<PKGBUILDDIR>>/gcc/build'
make[3]: *** [Makefile:1064: all] Error 2
make[3]: Leaving directory '/<<PKGBUILDDIR>>/gcc/build'
So, gnatbind does not exist because it has been renamed prematurely.
As pointed out by Helmut Grohne in #924325, there seems to be a missing
dependency somewhere, but as far as such missing dependency is not spotted
and fixed, the attached patch (which just does "cp -p" instead of "mv")
will be a lot better than nothing.
Note: The proposed patch is against gcc-14. I have actually tested the patch
and it works (using the generated "gcc-14-source" package to build
gcc-14-cross).
The same patch should apply to the other gcc-nn packages.
To reproduce the build failure, please try GRUB_CMDLINE_LINUX="nr_cpus=1".
The failure rate seeems to be 100% that way. Failed build logs
will be like this:
