libmetis does not link GKlib

Question

libmetis does not link GKlib

aliaksei135 opened this issue 2 years ago · comments

The METIS library depends on functions from GKlib however this is not linked to the metis target in CMake. Instead GKlib is linked against the program binaries in programs.

Using libmetis standalone results in errors missing refs to various gk_* routines

...
undefined reference: 'gk_malloc'
...

You need to link your programs both against metis and GKlib; i.e., "-lmetis -lGKlib".

Using CMake to build libmetis.dylib will generate a linker error showing that it is not linked to GKlib. I found that this is because in CMakeList.txt in libmetis folder, there is no command to order metis to be linked to GKlib. So I added a line target_link_libraries(metis GKlib), and then CMake can complete the building. Hope you can review this and make proper revisions to the package.

Thanks! This fixed it for me!
