Description Siraj Razick 2012-02-06 11:14:49 UTC

We recently refactored telepathy gabble plugin api so that there is a separate library which the plugins
can link agaist, and contains the symbols needed by the plugins. 

unmerged branch can be found at : http://cgit.collabora.com/git/user/siraj/telepathy-gabble.git/log/?h=buildbot_rebased 

We have one more issue standing in  our way from merging this. When building this patch for 64bit architecture, we get the following error.

 /usr/bin/ld: ../lib/ext/telepathy-yell/telepathy-yell/.libs/libtelepathy-yell.a(base-call-channel.o): relocation R_X86_64_32 against `.text' can not be used when making a shared object; recompile with -fPIC

So Olli suggested we add -fPIC option to AM_CLAGS and rebuild them. this bug is to find the best solution.

There's a sibling bug coming for yell; the same kind of error results for both though.

The core issue: Gabble pulls in Yell and Wocky as submodules. They're compiled as static libraries. However, now symbols from them are used in a shared library containing the Gabble plugin API; this shared library doesn't link correctly on most non-x86 architectures, such as x86_64, because not all code in it is position-independent.

Fixed by Gabble build passing CFLAGS="-fPIC" to the submodule configure scripts.
