Lahey Fortran Compilers

Lahey/GNU and Lahey/Fujitsu Fortran Compilers

Polyhedron has had a long relationship with Lahey offering local sales and support of its compilers for over many years.  This partnership resulted in the announcement of Polyhedron being appointed worldwide distributor of Lahey-Fujitsu compilers in 2006.  The compilers are available in a variety of configurations for Windows 32-bit, Linux 32-bit and Linux 64-bit, and recently the Lahey GNU 32/64-bit Windows compiler. They can either be purchased from our on-line shop or from one of the many authorized worldwide resellers.
