It= might be useful to use later versions in some cases, but anyway, that woul= d be great! It would mean sticking to a single version, but I'd be pretty surprised if mixing them ended well so that's probably for the best. > It would also be awesome if base clang would be able to find omp.h and li= bomp more "out of the box" once the package is installed... libomp is pretty easy once I realized I needed to hardcode the path to the .so, I'll have to see what's involved for omp.h. -- Brooks --z4+8/lEcDcG5Ke9S Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJYIRHmAAoJEKzQXbSebgfAcEQH/3UA2GIrzBTxI8HElFeLGTKL xqQtWwp5uWFCv2GqAuohaxQkxkbJyz08Nqpv/+xmm02guSaZCKzD/rLhvuwKPisB CJIWYj6f12m5ycpir672aQb0YiV+a7RFlBOJKWXS1TEUsMjs0OAU0zul3QdqLi+M zx8YVfA0BLUCVyv5qpomCHJV4zGhhhmlMZOPiOffltolaDbrAPqUPC9/wM91xNUy c5l/PsPwD8qtl8Q6n+6qvnq4NOHTQTo+GMVv2+TficF1ffy7BubtqIs7chCv93qG E4FTQ2xdeO5BX8IjqU0T4l5262Skt91gdQHvYBuAM7woDBNcPIIlnDf+1qcVcoo= =Bap/ -----END PGP SIGNATURE----- --z4+8/lEcDcG5Ke9S--
