Bug#474080: mpfi: Please add shared library support

[Laurent Fousse]

Hello,

* Laurent Fousse [Fri, Apr 04, 2008 at 01:49:06PM +0200]:
 Thanks for your work on this issue. I'll see with upstream before
 inclusion in debian.

I'm packaging latest CVS version, which includes a shared library. The
upload should happen sometime this week.

Cheers,

Laurent.

Bug#474080: mpfi: Please add shared library support

[Laurent Fousse]

Hello,

* Timothy G Abbott [Thu, Apr 03, 2008 at 02:19:14AM -0400]:
 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.

Thanks for your work on this issue. I'll see with upstream before
inclusion in debian.

Laurent.
