Re: Latest for buildworld + clang + ccache
23.11.2012 10:59, Beeblebrox: 9.1-PRERELEASE #2 r242867: When will buildworld + clang + ccache be functional? I think I read somewhere that buildworld + clang - ccache was working fine now. Any info on date ccache will work with clang and when to try? Define CCACHE_CPP2 as otherwise clang will yell at ccache trying to compile precompiled source with extra flags. This breaks libtool and a some other autoconf tests. Care to not specify CCACHE_CPP2 for virtualbox and friends. Also, clang users - do you see any speed advantage for kernel / world / ports built with clang?

Re: Latest for buildworld + clang + ccache
Hello, 2012/11/23 Beeblebrox zap...@berentweb.com: 9.1-PRERELEASE #2 r242867: When will buildworld + clang + ccache be functional? I think I read somewhere that buildworld + clang - ccache was working fine now. Any info on date ccache will work with clang and when to try? Can't comment on this. Also, clang users - do you see any speed advantage for kernel / world / ports built with clang? It's not really noticeable but some benchmarks were published on the lists (maybe current@ ?) some days / a few weeks ago, and I remember that buildworld is ~= 10% faster with a clang-compiled kernel + world than with a stock (old 4.2) gcc-compiled kernel+world. I'm not speaking of the compiler speed but really the speed of the same build when run under a clang- or a gcc-compiled base system.

Re: Latest for buildworld + clang + ccache
Thanks to both. Care to not specify CCACHE_CPP2 for virtualbox and friends. Not true for Jails I assume? Define CCACHE_CPP2 as otherwise clang will yell at ccache Is this the same reason CMAKE yells at CCACHE? -- View this message in context: http://freebsd.1045724.n5.nabble.com/Latest-for-buildworld-clang-ccache-tp5763430p5763438.html Sent from the freebsd-stable mailing list archive at Nabble.com. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

No, it's just that virtualbox still doesn't build with clang and gcc doesn't really like some -MD (?) flags. Define CCACHE_CPP2 as otherwise clang will yell at ccache Is this the same reason CMAKE yells at CCACHE? Haven't seen this before.

Re: Latest for buildworld + clang + ccache
Is this the same reason CMAKE yells at CCACHE? Haven't seen this before. Can you share? I meant for ports, not buildworld... I use bsdadminscripts and specify preferences in /usr/local/etc/buildflags.conf. I tried these and did not work. What is the setting for this, and I assume I can set CCACHE_CPP2 in that file also?

Re: Latest for buildworld + clang + ccache
I think maybe it has to be like this: BUILDFLAGS_GCC_CC= clang BUILDFLAGS_GCC_CPP= clang BUILDFLAGS_GCC_CXX= clang But BUILDFLAGS_GCC_CXX looks at CCACHE_CPP2 I think and must be modified. -- View this message in context: http://freebsd.1045724.n5.nabble.com/Latest-for-buildworld-clang-ccache-tp5763430p5763447.html Sent from the freebsd-stable mailing list archive at Nabble.com. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

Re: Latest for buildworld + clang + ccache
It breaks while spitting all these errors.
