This is actually an upstream problem. It is trivial nowadays to add
Libtool support to a package and have shared libraries available. I am
attaching below two slim patches for the glpk package which add Libtool
support. The first patch regards only the upstream files, while the
second is for the Debian specific files.
After applying the patch, the usual "aclocal; libtoolize; automake;
autoconf" must be run, of course. The built package contains:
$ debc | grep /usr/lib
drwxr-xr-x root/root 0 2005-05-24 08:58:22 ./usr/lib/
-rw-r--r-- root/root 520060 2005-05-24 08:58:22 ./usr/lib/libglpk.so.0.0.0
-rw-r--r-- root/root 802 2005-05-24 08:58:20 ./usr/lib/libglpk.la
-rw-r--r-- root/root 661238 2005-05-24 08:58:22 ./usr/lib/libglpk.a
lrwxrwxrwx root/root 0 2005-05-24 08:58:20 ./usr/lib/libglpk.so.0 ->
libglpk.so.0.0.0
lrwxrwxrwx root/root 0 2005-05-24 08:58:20 ./usr/lib/libglpk.so ->
libglpk.so.0.0.0
Please consider applying this patch either upstream or in the Debian
package.
