I am trying to build ITK with a non-system-standard compiler. I did so
by running:
ccmake ../../src/ITK/
-DCMAKE_CXX_COMPILER=/home/doriad/src/gcc-4.5.2/bin/gcc/g++
However, I get:
---------------
CMake Error at /usr/share/cmake/Modules/CMakeTestCXXCompiler.cmake:45
(MESSAGE):
The C++ compiler "/home/doriad/src/gcc-4.5.2/bin/gcc/g++" is not able to
compile a simple test program.
It fails with the following output:
Change Dir: /home/doriad/bin/ITK/CMakeFiles/CMakeTmp
Run Build Command:/usr/bin/gmake "cmTryCompileExec/fast"
/usr/bin/gmake -f CMakeFiles/cmTryCompileExec.dir/build.make
CMakeFiles/cmTryCompileExec.dir/build
gmake[1]: Entering directory `/home/doriad/bin/ITK/CMakeFiles/CMakeTmp'
---------------
This is indeed the correct path for the compiler:
[doriad at daviddesktop ~]$ ~/src/gcc-4.5.2/bin/gcc/g++
g++: no input files
I tried creating a fresh build directory and nothing changed. Any
suggestions of what else to do to use this compiler?
Thanks,
David
