As I understand currently x86 and amd64 are also broken for lang/gcc6-aux if built from a recent enough head (ino64). True historically (x86/amd64) but briefly there was a little more, at least for a native aarch64 context if I understand right. (Possibly armv6 and/or armv7 too?) My understanding is that there was a short time when aarch64 also had Ada going via lang/gcc6-aux . But the problem of gcc's technique of adjusting system headers so it has separate copies (supposedly to force the headers to be language complaint) vs. FreeBSD making updates to various headers that has gcc copied and adjusted broke the bootstrap compiler's ability to do the bootstrap. (A compiler involved in the bootstrap for aarch64 is actually retrieved from elsewhere as part of the build as I remember. But it processes the headers that are as of when the bootstrap compiler was built and made its adjustments.) In other words: the overall mechanism (FreeBSD+gcc) is fragile and both sides tend to think that the other side should be the one to change how they work in order to remove the fragile status. The two parts just do not fit well and no minor variations in how the two operate can remove the mismatch. I happened to do my attempted experiment that involved building ports-mgmt/synth on aarch64 after things had broken. (I did not try armv6/v7 but there might have been a short time when there was context in that area that worked as well.) aarch64 (and any others) did not last long. Powerpc, powerpc64, mips, etc. have never attempted for Ada support as far as know. === Mark Millard markmi at dsl-only.net _______________________________________________ freebsd-ports@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
