Argobots automatically builds with Intel compiler #82

Open jolivier23 opened 5 years ago

jolivier23 commented 5 years ago

For now, we have worked around this by setting CC=gcc during configure stage.

But I have a suggestion when building with icc to consider using -static-intel flag. This causes Intel libraries to be linked in statically and avoids issue of not being able to link with libabt.so without either using the Intel compiler or at least having the Intel compiler libraries in the library search path.

Thank you for your suggestion.

For now, the workaround is ./configure --prefix=[...] CC="icc -static-intel"; it can remove all Intel dependency from libabt.so as far as I checked with icc17.

I personally think that -static-intel can be a default behavior. As far as I tested, they don't produce link-time errors when I try to link multiple libraries compiled with -static-intel etc. I cannot assure that this modification causes any side effects, though.

If no one points out side effects and you think ./configure CC="icc -static-intel" is too hacky, we can add this flag by default when icc is used.
