Package: mpfi
Version: 1.3.4~rc3-1
Severity: wishlist
Hello,
I'm working on packaging SAGE for Debian, which links against libmpfi.
However, I'm getting linking problems on amd64 because libmpfi in debian
is not compiled with -fPIC (as it should be).
The right solution to this is that I should link against the shared
library version of libmpfi which would be built with -fPIC.
Making mpfi build a shared library requires some minor changes to the
Makefile.am and configure.ac files and running autotools (patch attached).
There's additional work that needs to be done in terms of setting up the
right shared library versioning and making the new shared library package
(and ideally convincing upstream to include the shared library), but I've
attached the patch I constructed to build the shared library for my
development use in case it saves you some time.
