Bug 87820 – media-libs/libmpeg3 needs -fPIC on amd64

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Paul Betts 2005-04-03 11:17:40 UTC]

Emerging libmpeg3 on the default AMD64 2005.0 profile fails because -fPIC is not specified in the Ebuild. Unfortunately, several major programs depend on this library (kdemultimedia, k3b, mplayer), so a lot of things don't work as a result.

Reproducible: Always
Steps to Reproduce:
1. emerge libmpeg3


Actual Results:

x86_64/audio/ac3.o: relocation R_X86_64_32S against `a local symbol' can not be
used when making a shared object; recompile with -fPIC
x86_64/audio/ac3.o: could not read symbols: Bad value


Expected Results:  
Compiled cleanly
