That’s obviously a linking stage of a simple “int main(){ return0;}”, see
https://github.com/dealii/dealii/blob/master/cmake/macros/macro_check_compiler_setup.cmake
<https://github.com/dealii/dealii/blob/master/cmake/macros/macro_check_compiler_setup.cmake>
# This macro tries to compile and link a simple "int main(){ return 0; }
# with the given set of provided compiler and linker flags and an optional
# list of libraries to link against.
I have no idea why linker hangs, I never saw such issues (ideas anyone?).
I would still suggest adding extra CMake output, just move
https://github.com/dealii/dealii/blob/master/cmake/setup_finalize.cmake#L95-L102
<https://github.com/dealii/dealii/blob/master/cmake/setup_finalize.cmake#L95-L102>
infront of `CHECK_COMPILER_SETUP` to see what are the final values of all flags
and if they make any sense.
Kind regards,
Denis
