Right, it is a hack (after all it is a work around) I was just curious to know where it wouldn't work... and I also wanted to make sure that the eclipse generator is feeding the manually added definitions correctly to the IDE. However, please do add this as a feature request at: http://public.kitware.com/Bug/my_view_page.php The following lines seem to dump the needed information: echo | gcc -v -x c -E -dD - echo | gcc -v -x c++ -E -dD - Add any other relevant information; even patches are welcome ;) --Miguel _______________________________________________ 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
