Secondly, I think all you have to do to install XCode is to download it from the App store. While XCode tools still has a command-line C++ compiler, In recent versions of OS X (I think 10.7 and later) have switched to clang/llvm (mostly because Apple wants all the benefits of Open Source without having to contribute back and clang is BSD licensed). You can download XCode for free (well, mostly, you do have to sign up to become an ADC member, but that's free too) here: Įdit : This answer was correct in 2010. They've hacked on it a little, but basically it's just g++. That's the compiler that comes with Apple's XCode tools package. You are done! The compiler can be envoked by the commands fc or f2c. The script will grab f2c source from Netlib repositories and install a f2c based compiler in /usr/local/. Its been around since OS X was in a public beta state. This is the oldest Fortran compiler available for OS X. $ gunzip (if your browser didn't do so already)

On 10.9 Mavericks, you can get the command-line tools by simply typingĢ) Download one of following binaries Binaries: (PowerPC only), You will find the option to download the command-line tools in XCode's Preferences (click on Downloads tab). LION, with XCode 4 or 5 you will need to download the command-line tools as an additional step. You will need to have Apple's XCode Tools installed from the Mac App Store. Future versions of GCC will have gfortran (see above). G77 3.4: This is the FINAL release of g77 (version 3.4 compiler). You can invoke the Fortran 95 compiler by simply typing gfortran, as following example: , (gfortran only), updated July 2012 (Lion & M. , (gfortran only), updated Oct 2013 (M. , (gfortran only), updated Oct 2013 (10.9 Mavericks only). On 10.9 Mavericks, you can get the command-line tools by simply typing ġ) Install Xcode: You will need to have Apple's XCode Tools installed from the Mac App Store. modify code to take advantage of AltiVec/SSE, automatically) and other sophisticated optimizations like OpenMP. This contains current versions (4.7 is the stable release) of gfortran (free, open source, GNU Fortran 95 compiler), gcc (GNU C) and g++ (GNU C++) compilers that can perform auto-vectorization (i.e. GCC 4.7, 4.8, 4.9 (auto-vectorizing gcc with OpenMP):Ĭompiled using source code from the GNU servers.
