You should not need gcc-4.4 in Build-Depends unless your package will not build on any other version (which is a very bad bug), since gcc is build-essential and therefore already installed. You certainly should not need it at runtime. > Another problem that arises here: > > I autodetect OpenMP support using AC_OPENMP() autoconf macro.

If gcc 4.3 or higher is installed it should already contain the .so symlink that you need, so simply compile it as normal. No extra build-dependencies are needed. > libgraphicsmagick3 is also compiled with OpenMP support > (/usr/lib/libGraphicsMagick.a has omp_get_* and GOMP_* symbols > undefined), however it does not depend on "gcc-4.4". Again, you don't need to depend on gcc. Your package will probably have a dependency on libgomp1, but that will be automatically added if required. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
