Hi All,

The compiling of the latest Git kernel doesn’t work anymore for our FSL P5020/P5040 boards [1] since the random-6.12-rc1 updates [2].

Error messages:

arch/powerpc/kernel/vdso/vdso32.so.dbg: dynamic relocations are not supported

make[2]: *** [arch/powerpc/kernel/vdso/Makefile:75: arch/powerpc/kernel/vdso/vdso32.so.dbg]

Reverting of the vdso updates has solved the compiing issue.

Could you please check the random-6.12-rc1 updates? [2]

Thanks,
Christian

+ Kernel config

Link: https://raw.githubusercontent.com/chzigotzky/kernels/refs/heads/main/configs/x5000_defconfig

Your config has:

  # CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE is not set
  CONFIG_CC_OPTIMIZE_FOR_SIZE=y

But all our defconfigs use CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE. Which
explains why we didn't catch this in build testing. I've added a build
with OPTIMIZE_FOR_SIZE=y so hopefully we'll catch any similar errors in
future.

cheers
