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 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/.
