[Insight-users] debugging Itk code

[Xavier Mellado Esteban]

   Hi, Felix:

   Yes, as you said, you need to alter the build with ccmake, if you are 
using the "interactive" CMake. If you are using the command "cmake" you 
will need to alter the itk sources root CMakeList.txt file, but never 
the cache one...

   To be sure about what you are doing, set on the interactive ccmake 
always to "Release" or "Debug" in CMAKE_BUILD_TYPE setting, and do not 
touch release and debug flags set by CMake. Otherwise, if no build type 
is set, ITK will be compiled with the compiler default settings (I think 
if you do not specify anything to gcc, it uses -O2, so is a "release" 
build). Many people coming from Windows doesn't set properly this 
setting, because in .NET you select this using the compiler IDE, but not 
when create the project files with CMake.

                  I hope this helps you:
                                                       Xavi
