Lahey Compiler

Lahey/GNU Fortran for 32 and 64-bit Windows

Release “Silverthrone”

The Silverthrone edition of LG Fortran contains:
Automatic parallelizing compiler producing 32 and 64-bit executables

The Lahey Visual Studio Fortran development environment features a fresh build of GFortran, using the latest source code pulled from the stable branch of the repository, and the latest versions of the prerequisite packages.

Visual Studio 2015 Shell

LG Fortran comes with the most sophisticated development environment available – Visual Studio! The LGF compiler system will run in your choice of Visual Studio 2015, 2013 or 2012 development environments. Already have VS 201x? Lahey’s LG Fortran will install into your existing Visual Studio without a hitch.

Lahey’s Exclusive Visual Studio Fortran support

Realize the full power of Visual Studio to dramatically improve productivity with Lahey’s Visual Studio Fortran support. We think that once you work with a real Fortran development environment, you will never be able to go back to other minimal development environments.

LG Fortran Delivers!

LGF includes fresh builds of the powerful GNU Fortran auto-parallelizing compiler, linker, command line debugger, librarian, Microsoft’s Visual Studio 2015 Shell with Lahey’s exclusive Fortran support, integrated GDB debugger, the Winteracter Starter Kit WiSK for creating Windows GUIs and displaying graphics, support for creating DLLs, calling Windows APIs, online documentation, and a year of technical support. Also included is a coverage analysis tool that detects unexecuted code and performs range-of-operation checking, an execution profiler that helps tune program performance, and a companion optimized parallelizing GCC C compiler.
