I'm using the Bochs emulator and for my class we're using gcc 4.2.1. I believe I've gotten Bochs running, but now I need to compile our programs which are compatible with gcc 4.2/.1.
I understand OSX uses an alias for gcc 4.2.1, but how can I use gcc specifically and not clang?
Edit: GCC 4.6.3 not 4.2.1 sorry
You can install previous version of gcc pretty easily using homebrew.
If you have homebrew installed you can get gcc 4.9 by running
brew install gcc@4.9
After it is installed gcc will still map to the clang that came with your mac. The newly installed gcc will be installed at /usr/local/bin and be called something like gcc-4.
You can find the exact executable name using
ls /usr/local/bin | grep gcc
Hopefully 4.9 is close enough to 4.6 for your purposes.
