Description Pablo Greco 2018-07-22 16:56:54 UTC

Description of problem:
After the commit of "Proper support for parallel debuginfo and hardening flags" https://src.fedoraproject.org/cgit/rpms/kernel.git/commit/?id=edd5e6103200b85864a041ae99086bd37afa81d4
Cross compile of the kernel for armhfp doesn't work

How reproducible:
Always

Steps to Reproduce:
1. Download kernel src.rpm
2. Try to cross build rpmbuild -ba --target armv7hl --with=cross --without=perf --without=tools --without=debuginfo --without=pae --define="_arch arm" --define="_build_arch arm" --define="__strip /usr/bin/arm-linux-gnu-strip" --define "%_topdir `pwd`/" --define "dist .f29" SPECS/kernel.spec

Actual results:
Build fails with error
gcc: error: unrecognized argument in option '-mabi=aapcs-linux'

Expected results:
Kernel builds

Pushed fix to master (technical details in git tree for those interested). This didn't make it into the -rc6 tree but it should be in the next snapshot. I'll leave the bug open for someone else to verify it's fixed.

Comment 2 Laura Abbott 2018-07-26 18:49:28 UTC

Confirmed via IRC that this is fixed
