Description Andreas Westin 2018-09-12 18:23:53 UTC

Hi,

emerging glibc-2.27-r6 (and -r5) results in a compilation error:

/usr/lib/gcc/x86_64-pc-linux-gnu/8.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/8.2.0/crtbegin.o: relocation R_X86_64_32 against hidden symbol `__TMC_END__' can not be used when making a PIE object
/usr/lib/gcc/x86_64-pc-linux-gnu/8.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: final link failed: nonrepresentable section on output


Reproducible: Always

Just to clarify, this is using a hardened toolchain.

This breakage is caused by explicit mention of -fPIC / -fPIE in CFLAGS:
> CFLAGS="-march=native -O2 -pipe -fPIE -fPIC"

Normally you should hever add those flags to CFLAGS. Previous instance is bug #664340

Thanks Sergei, that solved the issue. I've had those flags there for a long time, completely forgot about them.
