How to Compile Kratos in Debug mode

Revision as of 15:02, 16 July 2013

In order to compile Kratos in Debug mode, you have to edit your compilation script 'configure.sh' by changing the line begining with '-DCMAKE_BUILD_TYPE':

Instead of -DCMAKE_BUILD_TYPE=Release, type:

   -DCMAKE_BUILD_TYPE=Debug

If your goal is to compile Kratos in Release mode, but containing all the source code information, instead of the previous option type:

   -DCMAKE_BUILD_TYPE=RelWithDebInfo

Keeping both a Release and a Debug version of Kratos at the same time:

You will notice that switching from one compilation to another takes long, since all the source code is completely re-compiled when you change the compilation mode. A solution to this problem is to compile the code in different folders. This can be done by creating folders similar to the cmake_build folder. For instance, you can create an extra folder called 'cmake_build_debug' by doing this from the main kratos folder:

   mkdir cmake_build_debug
   cp cmake_build/configure.sh cmake_build_debug/configure_debug.sh

Then, edit 'configure_debug.sh' by setting the Debug mode with:

   -DCMAKE_BUILD_TYPE=Debug

Now you can compile the debug version of Kratos by doing:

   cd cmake_build_debug
   sh configure_debug.sh

And you can compile again the release version of Kratos by doing:

   cd ../cmake_build
   sh configure.sh

Now, both versions coexist.

When you run a Python script that calls the Kratos library, it will call the last one you compiled.
