[Dune] Problem linking with Pametis / GMP

[Sahai, Amal]

Hi Christoph

Thank your for your reply. Yes, I misspoke and this is a Cmake configure issue. I did try deleting the build directory and re-running cmake, but it does not change the outcome. Won't the following command in the FindParMETIS module :

set(PARMETIS_LIBRARY ParMETIS_LIBRARY-NOTFOUND
    CACHE FILEPATH "Full path of the ParMETIS library")

result in ParMETIS_LIBRARY-NOTFOUND always being cached (which is what I am seeing)?. In any case, I tried looking at the Error.log for the different modules and there is no additional information printed for the check_include_file call. The following excerpt is from CMakeError.log for the dune-fem-dg module:

Hi Amal,
your issue is no linking problem, it's a CMake (configure) issue.

Your setup looks ok and our CMake doesn't smell neither. Have you
deleted your build directory and re-run CMake? CMake is caching a lot of
checks and maybe the first run was without GMP and ParMETIS?

Is there nothing else related to the check_include_file call? Usually
there is a compiler invokation and some error output. If this is not
there, it's another pointer to caching. I'd like to see the output
error.log right afer deleting the build dir and re-running CMake.

Your analysis seems to be correct. I hope it's caching!

Bye
Christoph
