Peter Collingbourne's ongoing work with CMake support for ninja (and vice versa) was recently announced as being able to build multiple large projects:
http://public.kitware.com/pipermail/cmake-developers/2011-November/002490.html BRL-CAD was on the list, and in trials last night I confirmed that it does indeed build BRL-CAD - nice work Peter! The no-op build was indeed extremely fast (less than a second, vs. more than ten even with a parallel make), and the full build time was 8 minutes 43 seconds as opposed to 9 minutes 8 seconds for make (considering this is a Gentoo box and my compilation toolchains tend to be optimized, I was actually pretty impressed - I will be especially curious to see what happens on a Mac. It would be interesting to figure out a way to identify the "compiler time only" number and be able to characterize the actual make/ninja overhead, to know how close ninja comes to the ultimate least-time-possible build.) In case anybody else wants to give ninja a spin, here's what I did to test it (using bash as a shell): git clone git://github.com/martine/ninja.git git clone -b ninja-generator-pr git://github.com/pcc/CMake.git export PATH=/home/user/ninja:/home/user/cmake-install:$PATH cd ninja ./bootstrap.py cd ../CMake ./bootstrap --prefix=/home/user/cmake-install gmake && gmake install Then configure your projects as normal, but specify the Ninja generator: cmake -G Ninja and build with ninja instead of make: ninja You can also specify individual targets - for example, if I want to build just the main editor of BRL-CAD I can do: ninja mged -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
