Having looked at the examples, this one is similar to what I tried (and fails to build):
compilers.choose fc cc compilers.setup require_fortran -g95 -clang :info:build make: *** [ccx_2.18.a] Error 1 :info:build make: Leaving directory `/opt/local/var/macports/build/_Users_marbre_ports_cad_CalculiX-ccx/CalculiX-ccx/work/ccx_2.18/src' :info:build Command failed: cd "/opt/local/var/macports/build/_Users_marbre_ports_cad_CalculiX-ccx/CalculiX-ccx/work/ccx_2.18/src" && /usr/bin/make -j1 -w CC=/usr/bin/clang FC= CFLAGS="-O2 -I../../spooles-2.2/ -DARCH=Linux -DSPOOLES -DARPACK -DMATRIXSTORAGE -DUSE_MT=1" DIR="../../spooles-2.2" :info:build Exit code: 2 :error:build Failed to build CalculiX-ccx: command execution failed :debug:build Error code: CHILDSTATUS 48534 2 :debug:build Backtrace: command execution failed :debug:build while executing :debug:build "system {*}$notty {*}$callback {*}$nice $fullcmdstring" :debug:build invoked from within :debug:build "command_exec -callback portprogress::target_progress_callback build" :debug:build (procedure "portbuild::build_main" line 8) :debug:build invoked from within :debug:build "$procedure $targetname" whereas adding a whitelist succeeds (using gfortran): compiler.whitelist macports-gcc-11 compilers.choose fc cc compilers.setup require_fortran -g95 -clang Is this a difference between mp and apple gcc?
