Lahey/GNU Lahey/Fujitsu Fortran Compilers

Polyhedron has had a long relationship with Lahey offering local sales and support of its compilers for over many years.  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.

Lahey's Linux compilers are no longer under development or supported, so we recommend that you try before you buy.
