#2588: defaults for XXX_OPENMP_FLAGS differ between linux and darwnin architectures

Reporter: Roland Haas Status: new Milestone: Version: development version Type: bug Priority: trivial Component: Cactus

Cactus known-architectures files `lib/make/known-architectures/linux` and `lib/make/known-architectures/darwin` differ in whether they set defaults for `XXX_OPENMP_FLAGS`. Namely the Linux one contains:

``` ib/make/known-architectures/linux: : ${CXX_OPENMP_FLAGS='-fopenmp'} lib/make/known-architectures/linux: : ${CXX_OPENMP_FLAGS='-openmp'} lib/make/known-architectures/linux: : ${CXX_OPENMP_FLAGS='-mp'} lib/make/known-architectures/linux: : ${CXX_OPENMP_FLAGS='-openmp'} lib/make/known-architectures/linux: : ${CXX_OPENMP_FLAGS='-qsmp=omp'} ```

while the darwin (macOS) one does not set any defaults. Other architectures (aix) set a them as well while yet others (all others) do not.

Ideally the defaults should be the same for all architectures (and nowadays probably `-fopenmp`). The value of `OPENMP` itself (ie if OpenMP is used) is not set by any architecture file.
