If you are using gcc, you have two options: 1) Install one of the lang/gcc* ports (Warner has been working on = separating out the patches to our GCC, so these should soon be patched = to provide the same features as the one in base) 2) Put WITH_GCC=3Dyes and WITH_GNUCXX=3Dyes in your src.conf when you = build world. GCC will stay in the base system tree for at least the lifetime of the = 10.x release, and possibly longer if it is still being actively used. = It will remain used by tinderboxes and make universe for some = architectures, so if you commit code without testing with gcc people = will know very soon... Thanks to Warner for all of his recent work on disentangling the = toolchain, to all of the people (Roman, Dimitry, Brooks, and others) who = worked on getting clang integrated into FreeBSD and to everyone who = tested it and filed bug reports. As of today, PowerPC64 joins x86 and = ARM as platforms where world+kernel can be successfully built (and work) = with clang (although it isn't the default yet and needs more testing), = and hopefully other architectures will follow soon. Huge thanks to all of the ports people who have spent the last two weeks = working on dealing with the fallout from iconv and ensuring that all of = the ports work with clang and libc++. I think over the last week, the = number of failing / ignored ports has dropped by about a thousand a day = on the no-gcc test box that Bapt has been running, which is a phenomenal = achievement. =20 David=
