I recently had to help out a CMake newbie, who had run CMake in the source directory. Then he re-read the instructions on build setup for our programs, and did it the right way -- i.e. he configured a build directory for an out of source build.
Problem is, if you run CMake and configure the source directory, CMake will assume you want an in-source build, even if you try and configure an out-of-source build directory. So you get this mystifying behavior. # sourcedir is 'test', in same directory as test-build cd test # source dir cmake # whoops, configured in the source directory! cd ../test-build # come to senses, go to out-of-srouce build. cmake ../test # try configuring for out of source build make # now you get a "Makefile not found" error! In order to get rid of the problem you have to delete CMakeCache.txt in the source directory -- at a minimum -- before you can configure the out-of-source build. I ended up going through the source code trying to get rid of CMake droppings, which are numerous! _______________________________________________ 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
