Description Dominik 'Rathann' Mierzejewski 2015-07-27 08:40:55 UTC

Description of problem:
libpthread.a is compiled without -fPIC, causing linking errors in other packages, for example prelink.

Version-Release number of selected component (if applicable):
glibc-static-2.21.90-18.fc24.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. checkout prelink f22 branch
2. try to build it in rawhide mock

Actual results:
/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/5.1.1/../../../../lib64/libpthread.a(libpthread.o): relocation R_X86_64_32S against `__stack_user' can not be used when making a shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-redhat-linux/5.1.1/../../../../lib64/libpthread.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status

Expected results:
prelink builds normally.

IMNSHO this is not a bug.  If you link against these libraries statically, you should link them statically too.

Agreed.

Why are you linking in a static libpthread to create a shared object?

That's actually a question for Jakub, as prelink is his code. However, since execstack is being packaged separately (bug 1247795), this will become moot unless someone wants to unretire prelink.

glibc-2.26.9000-44.fc28 provides static PIE support on aarch64, i686, x86-64.

GCC 8 will simplify matters by including the -static-pie option.
