Hello,

in case this helps anyone trying to compile OF on a Cray, I managed to get rid of the "Wl,-rpath" error by removing the Xlinker flag in the Make.inc for the scotch library compilation

Additionally, I needed to recompile the scotch library without the
DSCOTCH_PTHREAD option, otherwise the parallel run would not work
in the computing nodes and I would get an error like this

ERROR: SCOTCH_dgraphInit: Scotch compiled with SCOTCH_PTHREAD and program not launched with MPI_THREAD_MULTIPLE

as discussed here
https://github.com/easybuilders/easy...gs/issues/7093

Best wishes

Carlos
