I've been using Clang static analyzer & regular Clang from SVN with CMake for some time and I only have 2 problems with this. * When switching compilers some settings are lost, this is an annoyance when using ccmake, since I have custom includes that need to be entered in manually. * For some reason I need to manually add these include paths to my CXXFLAGS -I/usr/include/c++/4.5.1 -I/usr/include/c++/4.5.1/x86_64-unknown-linux-gnu/ Otherwise this works really well and gives especially good warnings & errors with macros, aside from the static checker. -- - Campbell _______________________________________________ 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
