If you are setting the CXX compiler, you should also probably be setting the C compiler.
I always use environment variables to do this: export CC=/home/doriad/src/gcc-4.5.2/bin/gcc/gcc export CXX=/home/doriad/src/gcc-4.5.2/bin/gcc/g++ ccmake ../../src/ITK If that still doesn't work, then inspect the contents of the file CMakeFiles/CMakeError.log to see what the actual errors are, and post them here. (CMakeFiles/CMakeOutput.log may also have relevant results in it...) HTH, David C.
