Re: [CMake] Cmake 2.8.4 and gcc 4.6 on OSX
I got it from here: http://hpc.sourceforge.net/ But that's just a pre-compiled version. If you compile gcc4.x yourself on your mac you'll see that it behaves the same way. I'm not trying to use any part of the Apple toolchain, so it makes perfect sense to me.

Re: [CMake] Cmake 2.8.4 and gcc 4.6 on OSX
Macports works, but be warned that if you use rtti, (exceptions, dynamic casting), make sure that you only link against C++ libraries using the same compiler. Macports errantly uses its own system libraries in its compiler's.

Re: [CMake] Cmake 2.8.4 and gcc 4.6 on OSX
I'm really sorry I answered this question. I personally hate macports, but it has its own version of cmake that won't work with the apple compiler: /opt/local/bin/cmake -DCMAKE_CXX_COMPILER=/opt/local/bin/g++ -DCMAKE_C_COMPILER=/opt/local/bin/gcc .. make VERBOSE=1 /opt/local/bin/g++-Wl,-search_paths_first -headerpad_max_install_names CMakeFiles/test.dir/test.cc.o -o test Regards, Juan On Fri, May 6, 2011 at 11:34 AM, Michael Allen jmal...@gmail.com wrote: What do you mean by Macports works?

There are plenty of people out there who work on macs that only want to use the posix stuff. I feel like I even tried using macports cmake and gcc and it didn't work actually.

Re: [CMake] Cmake 2.8.4 and gcc 4.6 on OSX
Ok so you're basically saying that I can just tell cmake that I want to use a different compiler then, I think that would actually work with my current compiler and cmake...
