I use OSX 10.10.5 need to compile some c++ code with an old version of gcc, namely 4.3.4. I don't think XCode provide that kind of tools. I suppose there is a way to do that by hand. How can I do that ?

  • Welcome to Ask Different. Are you going to make us guess your OS X version and the old gcc version you need? – bmike Sep 14 '15 at 10:38
  • @bmike I did not think it was OS specific. I have just updated my post – epsilones Sep 14 '15 at 10:50

I have compiled older gcc in the past as a last resort.

  1. Get Xcode - it gives you clang and lots of header files. If you can't stomach it, get the command line tools.
  2. Get http://brew.sh
  3. brew install gcc

From there you can see if an older gcc is available or worst case, pull that source and compile it from the version of gcc you have running from above. It looks like you'll be able to use homebrew to get at the version 4.3 from the versioned source already in the tool:

mac:~ me$ brew search gcc
gcc
homebrew/dupes/apple-gcc42       homebrew/versions/gcc44          homebrew/versions/gcc47          homebrew/versions/gcc5
homebrew/head-only/gccxml        homebrew/versions/gcc45          homebrew/versions/gcc48          homebrew/versions/llvm-gcc28
homebrew/versions/gcc43          homebrew/versions/gcc46          homebrew/versions/gcc49

  • I have already tried homebrew/versions/gcc43 and I get this message : ` OS X Mavericks or older is required.` – epsilones Sep 14 '15 at 11:14
  • @Newben Did you find the source of that message and look at the code? You could probably comment out the check and see what breaks. Or you'll need to just get the source and start fixing compile errors. That's the "last resort" I mentioned above. – bmike Sep 14 '15 at 11:18
  • ok thanks but I think it can be too complicated to fix it line after line, don't you think so ? – epsilones Sep 14 '15 at 11:22
