Since Apple have stopped distributing gfortran with Xcode, how should I compile architecture independent Fortran code? I've only found a single website that distributes a binary version of gfortran specifically for Mountain Lion: the HPC website. They provide instructions and a script for Building a Universal Compiler , but, again, this hasn't been updated for Mountain Lion yet..

The G95 project hasn't had an update since , so I didn't try it.. Anyone tried this on Mountain Lion? I guess this will be the easiest way to get gfortran installed, but port search gfortran comes up with nothing, and I've not had any joy with MacPorts in the past no offence to MacPorts; it's looks like a very active project, but I've been spoilt with Linux package managers, my favourite manager being aptitude so on Mac OS X I've compiled software and libraries from source code in the past.

How to UPGRADE your mac from Os X Lion 10.7.5 to High Sierra

Never been a problem 'til now Having dug around on the internet a lot in the last couple of days, I've found other Fortran compilers, but I've failed to get any to cross-compile universal binaries, or to compile SciPy. I compiled the entire GCC collection v4. DragonEgg is a "gcc plugin that replaces GCC's optimisers and code-generators This looks interesting, but I don't know how I could use it to compile 'llvm-gfortran Can this be done?

The compiler that comes with Xcode is a fork of? GCC v4. But GCC's current release and development branches are versions 4. So, if I was to build dynamic libraries made with GCC's gfortran v4. Do GCC provide backwards compatibility with Apple's forks of?


I know gfortran has the -ff2c flag , but is this stable across versions? Python's distutils, and probably other OSX compilers, expect these flags to work, when configured to build apps or frameworks, using Xcode's universal SDK. I don't use Xcode so much, but integration with it would surely benefit other users. Even Intel are still having problems integrating ifort into Xcode 4. If you read all the above, then thank you! You can probably tell that I'm not averse to building my own Fortran compiler from source, but is it even possible?

Have I missed something?

Optional tools and libraries

A configure flag maybe? And if such a compiler is not available yet, then why not?! Apple provide the source code for their patched version of GCC, at opensource. This actually includes the source code for gfortran, but what do you know - it doesn't compile easily.

Step #2: Install gcc/LLVM compiler on OS X

I'm in the process of writing a build script to get this to work. Unfortunately, I've had to apply a couple of patches, and learn about "the Apple way" of building GNU software.

This is the way to go I think. Any reasons why it shouldn't be? I'll update with an answer if I get it to work I had to try to open the package a couple of times, though. First time it said that only apps from App Store can be installed. After installing gfortran, python setup. The unit tests of scipy though give a fairly high number of fails, not sure it's normal. In case you didn't already notice this: In newer versions of Xcode you have to explicitly install command line tools in the following way:.

Admittedly, this does not solve all of my fortran needs in some cases ". You could use brew or Homebrew to install gfortran. I know you said you don't like MacPorts, but if you install the gcc48 port, it does in fact include gfortran although you'll also have to do sudo port select --set gcc mp-gcc48 to get it to set up the symlink named gfortran.

On the other hand, it also sometimes seems to get archived binaries from somewhere, but I think it depends on what the original author of the portfile uploaded. Smyrlis 1 1 gold badge 1 1 silver badge 7 7 bronze badges.
