[Libunwind-devel] [PATCH] Create and install pkg-config .pc files

[Alexander Toresson]

Hello all,

I've made a patch for creating pkg-config .pc files for libunwind. For
example for libunwind-ptrace, you seem to need to also link to
libunwind-$arch (for example libunwind-x86_64), or at least this is
the case on x86_64 (please correct me if this is not the case for the
other architectures). So I thought that this could be automated with
pkg-config. For example, with this patch on x86_64, pkg-config --libs
libunwind-ptrace outputs "-lunwind-ptrace -lunwind-x86_64". For
completeness, this patch adds .pc files for all the libunwind
libraries.

Except for libunwind-ptrace, libunwind-coredump also appears to need
libunwind-$arch, while libunwind-setjmp does not. Is this correct?

I have only had the chance to test this patch on x86_64, I encourage
testing, comments and corrections!

Regards, Alexander
