[yocto] Non-deterministic build error in package gcc-source

[Erik Nellessen]

We are building an operating system based on poky (f0ec7c8b2dc1797ba22c45653a5f182b63354092, bitbake: toaster: add 'Sumo' to release selection).


Sometimes (about 1 in 10 times) our build fails, because the task do_ar_patched fails for package gcc-source-7.3.0-7.3.0-r0.


The short error message:

14:44:09 Exception: FileNotFoundError: [Errno 2] No such file or directory: '/home/jenkins/workspace/_Config_mguard_0.1.0_MG-254-QLU3J23WOWLZZG76AVHU5BVY3M7SIU3EOQQQSUQNOEXHTXRFTQMQ_2/build/qemux86-64_tmp/work-shared/gcc-7.3.0-r0/gcc-7.3.0/gcc/gengtype-lex.c'

I attached the full error message as a text file.


Does anybody know this error message? Does anybody experience similar problems with non-deterministic build failure?


Kind regards,

Erik
