If you are setting the CXX compiler, you should also probably be setting the C compiler.<br><br>I always use environment variables to do this:<br><br> export CC=/home/doriad/src/gcc-4.5.2/bin/gcc/gcc<br> export CXX=/home/doriad/src/gcc-4.5.2/bin/gcc/g++<br>
ccmake ../../src/ITK<br>
<br>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...)<br>

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