Apple's Xcode Developer Tools (at least version 3.2 for.There are many ways to install these open source FORTRAN compilers on Mac OS X, you could build the compilers from the source or just install the binary packages, or from the way between: using porting system to build them automatically.īefore I write anything about the getting the compilers for your Mac OS X, you should at least have installed:

G95 has some advanced feature like coarrays, but gfortran does have something g95 doesn't have: OpenMP. g95 is more conservatively and independently developed while gfortran integrates itself to the mothership - gcc source tree. These two compilers originates from the same group of people but the diverged due to the difference of project managing styles.

There are two popular open source licensed FORTRAN 90 compilers, g95 and gfortran. AbSoft PRO Fortran, NAG Fortran 90, IBM XL Fortran 9 and Intel Fortran are some fine compilers that require some funding. FORTRAN 90 compilers are not provided by Apple in developer environment therefore FORTRAN developers need to acquire a third party compiler by themselves. Besides a C compiler, AMBER installation requires a FORTRAN 90 compiler, this has been the case since AMBER 8.
