Hi,
in my periodically upgrade process I've found a general problem that can be detailed in pango build.

Every time I build I get the error:
/usr/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../lib64/libm.a(k_standard.o): relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../lib64/libm.a: could not read symbols: Bad value

I've seen ad adopted the solution in http://www.gentoo.org/proj/en/base/amd64/howtos/index.xml?part=1&chap=3 without success.

I've tried to rebuild automake and autoconf but nothing change.

At this point I've tried to rebuild glibc but I've find another problem about libunwind.

The problem doesn't happen only with pango but this is the first occurence.

Provide outputs of

$ ls -ld /usr/lib/libm.so* /lib/libm.so*
$ file /lib/libm*.so*
$ ls -ld /lib /lib64 /usr/lib /usr/lib64

In other words, verifying the correct symlinks are in place and libm.so is available and working

That is wornderful!

Some day ago I have relocated /usr/lib64 to another filesystem.

All the relative symlinks to /lib64 was failed .

I've recreated all the symlinks and now pango has been build correctly.

Can you explain how do you diagnose the problem from that error!?!

I can't understand.

From this:

/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../lib64/libm.a

If the compiler can't find the shared library, libm.so, when linking with -lm, it will fallback to the static archive, libm.a

So the first thing that occured to me was:

Why would pango be linking to the static archive?
No reason. Where did his shared library go?

;-)

Closing then

Thanks for your explanation
