I finally figured out the problem with -Xclang option being passed to the Fortran compiler.
If you take a look at CMakeLists.txt at line 1098 you will see: if (OpenMP_C_FLAGS) This needs to be changed to: if (OpenMP_C_FLAGS AND NOT APPLE) The case for APPLE is handled properly below that clause. Happy to submit a pull request for that... alex K6LOT _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
