System Requirements

MXML XML Parsing Library

Version 2.2.2 of mxml is required. Earlier versions have a bug and the XML API will not work. This package can be downloded in both source and binary rpm form and is also available as part of Fedora Extras. IMPORTANT NOTE: Debian also provides the mxml package, but it based on 2.0 and will not work properly.

Building Notes

NAG F90/F95 Compiler

The NAG compiler needs the -mismatch flag to be specified or else it will not compile NXmodule.f90 This is achieve by running configure with the FCFLAGS environment variable set to contain the flag e.g.

env FCFLAGS="-mismatch" ./configure --with-f90=f95
