[Pkg-octave-devel] Bug#310226: octave2.9: FTBFS: linking a shared lib to a static lib fails.

[Kurt Roeckx]

Package: octave2.9
Version: 2.9.2-2
Severity: serious

Hi,

Your package is failing to build on a few arches (atleast hppa
and amd64) because when you're creating the shared lib you're
linking to a static version.  Static version should be compiled
without -fPIC while shared version must be compiled with it.
(See policy section 10.2)

This is giving the following error:
/usr/bin/g++ -shared -o __glpk__.oct pic/__glpk__.o -L../libcruft -lcruft -L../
liboctave -loctave -L. -loctinterp -llapack-3 -lblas-3 -lfftw3 -lamd -lumfpack

/usr/lib/gcc-lib/x86_64-linux/3.3.6/../../../../lib64/libglpk.a: could not read

There are some solutions for this:
- Ask the glpk maintainer to provide a shared lib.  This
  is ussually the prefered solution.
- Ask the glpk maintainer to provide a special static pic
  (libglpk-pic.a or something) version and link to that
  version.  This solution ussually isn't want you want.
