Visit the GCC Wiki GFortranBinaries page and scroll to the MacOS section.

The "GCC Wiki" implementation described in the following procedure is typically the newest binary release of gfortran, but requires that you download a version appropriate for your architecture.

Important: Install only one implementation of gfortran, as each version would overwrite portions of the others! These implementations vary by version, platform supported, and integration with XCode Tools.

However, various implementations of gfortran have been compiled and are available at GCC Wiki GFortranBinaries, Tools - R (and Fortran) for Mac OS X, or High Performance Computing for Mac OS X. gfortran replaces the gnu g77 compiler and is included with gnu compiler collection (gcc) 4.0 and higher.Īlthough Apple XCode Tools includes gcc 4.X, it is not a complete implementation and lacks gfortran. It also promises to attempt following future fortran standards, such as fortran2003. As such, it should be backward compatible with fortran77 and fortran90. Gfortran is the new gnu fortran compiler, which attempts to follow the fortran95 standard.

G77 documentation is available at GCC Online Documentation.

You may wish to replace the "-p" switch with "-t" so that you are not prompted to delete each file. $ tar -tf g77-bin.tar | sort -r | (cd / xargs -p -n 1 rm -d)

Provide your password for the installation will proceed.

In particular, Developer Tools Essentials should be unchecked (saving you 2.5GB of disk space)!

Uncheck all the components and check only Unix Development Support.

Follow the prompts, but at Installation Type, click the Customize button. Navigate to the Optional Installs: Xcode Tools folder. However, they are not installed by default. These utilities, together with the c compiler for OS X, are available as part of the Xcode Tools that come with OS X. ) when developing and compiling a project.

The procedures discussed on this page have been designed for Mac OS X 10.5. While integrated development environments (IDE's) are useful in supporting program development, this resource concentrates on the command line interface (CLI) using the Terminal application that is supplied with OS X. This resource concentrates on fortran compilers and the tools needed to support them.

Most (though not all) computational engines supported by WebMO are written in fortran.

), a substantial base of scientific code is written in fortran.

It is a versatile computing platform suitable both for computational chemistry calculations and for developing and compiling programs.Īlthough scientific programs use a variety of languages (basic, pascal, c, java, perl, python. The Mac OS X operating system is a variant of unix (called Darwin, which is a derivative of BSD unix). Fortran Compiler Installation Instructions for OS X
