...s buildbot: http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-debian-fast It uses CMake/ninja, which will give you the best possible iteration time. In order to use ccache, you need ensure that these environment variables are set: CC="ccache clang" CXX="ccache clang++" CCACHE_CPP2=yes export CC CXX CCACHE_CPP2 (Of course, you can use gcc/g++ as compilers.)

A quick question while I am adding a tiny section on ccache to the HowToAddABuilder document: Why do you set CCACHE_CPP2 to yes? From reading the manual, I get the impression that this is much slower than the default and that it should only be used with tricky compilers or when debugging. Is Clang such a tricky compiler? If so, I suppose Clang should be fixed, not the ccache configuration. -- Mikael 2013/11/14...

Hi Dmitri, I am not using any kind of cache (didn't even know of ccache). I have now installed ccache. Perhaps ccache should be mentioned in the buildbot document so that every buildbot owner knows about it? It is currently running Arch Linux ARM. if there are good reasons to switch to something else, I'll be happy to do that, although I am generally very happy about Arch Linux.

I am doing a buildworld with clang on amd64 9.1-PRERELEASE #2 r242867. In /etc/src.conf I have "WITHOUT_GCC= yes". Compile progresses up to below then breaks: ===> usr.bin/xlint/xlint (all) ===> usr.bin/xlint/llib (all) lint -cghapbx -Cposix /asp/src/usr.bin/xlint/llib/llib-lposix lint -cghapbx -Cstdc /asp/src/usr.bin/xlint/llib/llib-lstdc ===> lib/clang/libllvmx86codegen (all)
