I don't know if UMFPACK is a very special library, but I though opm made quite extensive use of RPATH, and then the library will be found runtime as long as we have it installed somewhere (configured build time), should not be necessary to battle with static libraries? Joakim
Sendt fra min HTC ----- Reply message ----- Fra: "Alf Birger Rustad" <a...@statoil.com> Til: "opm@opm-project.org" <opm@opm-project.org> Emne: [OPM] Umfpack runtime dependendy is problematic Dato: tor., okt. 10, 2013 08:40 All upscaling codes now depend on umfpack (contained in the suitesparse package) being available at runtime. Unfortunately, suitesparse is not installed by default on cluster nodes, so codes will fail to run by default. I can see four possible solutions. The most convenient one being that suitesparse is installed by default over here. Unfortunately, that may be difficult to achieve, and will be of little value to the next user coming along with the same issue. The second being that we maintain the suitesparse libraries out of tree, pointing to them with LD_LIBRARY_PATH. This will probably work, so I guess this is what we will do right now, but it adds up the dependencies we have to maintain and sync out-of-tree. It will also be of little value to the next user coming along with the same issue. The third option is to compile umfpack with dependency (libamd.so on AMD systems I believe) statically. This will probably just work without issue for all users, but somebody will need to do the necessary cmake magic, and the static versions of the libraries will be a build time dependency. The fourth option is to remove the dependency on umfpack (didn’t it use to be an optional dependency?), not sure about the implications there. There is of course the fifth option of trying to get Red Hat et. al. to include suitesparse in a base installation, but I do not think that is realistic.
