System Requirements

Requirements for getting and building the ESMF software include:

• a Fortran90 or later compiler and libraries
• a C++ compiler
• if the C++ compiler is not gcc, a gcc compiler - we need this for a standard cpp preprocessor implementation
• a MPI implementation compatible with these compilers (but see below about our MPI stub library)
• the GNU make utility
• the tar utility, for unpacking data files
• the GNU zip utility, for unpacking data files
• the Perl programming language, for running test scripts
• latex, latex2html, and the Unix/Linux dvipdf utility are needed to build the ESMF documentation

An alternative to MPI, a MPI-bypass library, is bundled with the ESMF source distribution. It allows applications which use MPI to be linked but only run single process.
