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 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.
