If you use makefiel generator then calling it with "-j " parallel option should do the parallel building. Now if you are speaking of "running" the tests in parallel than it looks like even if ctest has the very same "-j" parallel option for running test in parallel the generated "make test" target does not forward the "-j " option given to make to the ctest call. i..e for me: ctest -j 3 runs 3 tests in parallel (when possible) whereas make -j 3 test does not. > All the ways I found to achieve that, essentially boil down to calling > make with multiple targets and that breaks parallel builds, due to race > conditions - multiple instances of make writing to the same files. > > Is there a way to build multiple tests in parallel ? -- Erk Le gouvernement représentatif n'est pas la démocratie -- http://www.le-message.org -- 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
