I happily used Flang 5 on FreeBSD 11. Now that devel/flang has been updated to 6, it is only available on FreeBSD 12: ------------------------------------------------------------------------ r479159 | jmd | 2018-09-06 21:11:06 +0100 (Thu, 06 Sep 2018) | 15 lines devel/flang[-clang]: update to later snapshots This introduces flang-driver, a clang6-derived driver / companion compiler, and uses math/libpgmath as the math library backend. Notably, the latter currently limits us to 12-CURRENT. Patches are a combination of carry-over and adapted OpenBSD ones. While there, pet portlint. Reviewed by: zeising (mentor), mat Approved by: zeising (mentor) Obtained from: Brian Callahan (bcallah@openbsd.org) with adaptations Differential Revision: https://reviews.freebsd.org/D17036 This is not ok! Please enable flang 5 on FreeBSD 11, maybe create devel/flang5, and devel/flang-clang5. Thank you!
It is clear that the future is the clang6-based flang with libpgmath. I will not maintain an outdated version of flang for FBSD 11. I encourage submission of patches to make the newer flang buildable on FBSD 11.
