[Trilinos-Users] [EXTERNAL] Re: linking in MPI tracing TPL

Hi Tom,

I'm probably wrong about this, but it occurs to me that the issue might be in the miniPIC configuration. Is miniPIC built separately from Trilinos, or as an extra repo inside Trilinos? If it's a separate configuration, then one has to transfer the information from ${TRILINOS_INSTALL_DIR}/lib/cmake/Trilinos/TrilinosConfig.cmake to the miniPIC configuration.

In the miniPIC CMakeLists.txt, you'd write something like
    find_package (Trilinos REQUIRED) # probably already in miniPIC's CMakeLists.txt
and then use this variable
in the target_link_libraries line.

One easy thing to check is the text of the link.txt file associated with miniPIC. The file is something like:
That shows the link line directly. If your library doesn't show up on that link line, then there's still a problem. Once it shows up, you should be good (unless there are some preprocessor defines associated with enabling functionality, in which case those would have to be specified as well).

You might try unwrapping the MPI compiler wrappers using, for example, 'mpicc show' and then use raw compilers.  See "Configuring to build using raw compilers and flags/libraries" under section "5.9   Configuring with MPI support" at:


That way, you can specify exactly the libraries in that you want in the order that you want.

I have not tried this in many years but it might work.
