Created attachment 2839 [details]
Patch I used to test with binutils-2.20.1

I ran into problems using buildroot to cross-compile mpc (and gcc-4.5.x for which mpc is a dependency).  The build would fail and the cross-compile-ld would complain that it couldn't find /lib//libc.so.0

It turns out this is a bug in ld from binutils that was fixed in binutils 2.21:
https://bugs.launchpad.net/binutils/+bug/625320

Basically ld ignores the sysroot path when absolute library paths are given, which causes errors when cross-compiling.

This issue affects any package that uses absolute library paths, such as mpc and others.  

The fix (which is basically this http://bugs.gentoo.org/attachment.cgi?id=195936) ought to be added to the buildroot patches for binutils versions prior to 2.21.

the patch hasnt been merged upstream, so why do you think 2.21 is fixed ?

I thought I had read that somewhere but I closed my windows and can't find that reference.  If it's not fixed in 2.21 then I misunderstood or misread something.

perhaps you interpreted the "fixed in ubuntu binutils-xxx" as "fixed upstream"

Fixed in git by Gustavoz, thanks.
