Hi Alexander, that's true, anyway we'll symlink /bin to /usr/bin in the next year. > Now if a Config.cmake files is installed into /usr/lib/foo/, and references > other files of its installations using relative paths from its own location > to e.g. /usr/bin/ (../../bin/ ), there is breakage. Note, that this only applies when $PATH contains a different order than the default one we ship; which is PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin". In detail, when /bin is before /usr/bin cmake looks for the binary in /bin. > CMake finds FooConfig.cmake in /lib64/foo/FooConfig.cmake (which it seems to > search before /usr/lib).

I'm not familiar with the cmake code, but I guess that the different PATH order I said above cause cmake to take the FooConfig.cmake file from /lib64 rather than /usr/lib. > If so, maybe the best thing to do is to tell the ArchLinux developers to set > up their symlinks in a different way ? > Having e.g. /usr/lib64/ point to /usr/lib/ would make it work I think. > Or if /lib64/ points to /usr/lib/, then maybe /bin/ should also point to > /usr/bin/. We are going to move everything to /usr. As I said above /bin will be symlinked to /usr/bin in the next year. -- Andrea Arch Linux Developer -- 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://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
