[CMake] CMake Digest, Vol 64, Issue 50

Wed Aug 19 21:33:56 EDT 2009

Couple more questions just to be clear.

Did you choose to build a "Makefile" based Eclipse project when you
created your project? If you just selected a "C++" project then
eclipse is trying to create its own makefiles for your project.

Are you using an "out of source build" for your project? For example,
do you have a "Build" directory within your project directory? Let's
say for example that you have created a "Build" directory inside your
project directory, then if you right click on the project in the C++
Projects view, and select properties. Then Select "Build", there is an
option to use the built in "make" or select your own command. Make
what ever selection is necessary to enable the use of your own "make
command". That command should be:

make -C ${workspace_loc}/mdc/Build VERBOSE=1

Then you can manually invoke the build for your project and see what happens.
