# Fortran Tools, Libraries, and Application Software

The Fortran Company is now offering FortranTools, a suite of tools consisting of gfortran, the open source Fortran 95 compiler with many F03 and F08 features; Code::Blocks, an open source graphical user interface for editing, compiling, running, and debugging Fortran programs; GTK-Fortran; OpenMP; procedures for creating graphical input and output with Fortran programs; GNUPlot plotting; several books in electronic form; the BLAS and LAPACK libraries with the MATRAN Fortran wrapper; interval arithmetic; and other tools.

- XML parser written by Mart Rentmeester
- HicEst is a Fortran-based Interpreter.
- make_pm generates a processor model and helps with interfacing Fortran with C/C++.
- Mathtools.net is the technical computing portal for all scientific and engineering needs. The portal is provided as a free service to the scientific community and contains useful links for technical computing programmers.
- The Fortran Interface Wizard automatically generates code for creating a Fortran DLL and interface code for using the DLL from Borland Delphi. A sample delphi project can also be generated. The program is GPL.
- COCO free source code from Purple Sage
- A vectorial graphical library in DXF.
- F2PY – Fortran to Python Interface Generator
- SansGUI, from ProtoDesign, Inc., is a modeling and simulation environment for developing and deploying scientific and engineering simulators without writing any graphical user interface code. SansGUI supports Compaq Visual Fortran for creating tightly-coupled and highly interactive in-process simulators. Other Fortran compilers can be used to create external process simulators.
- DESL, an integrated data manipulation/plotting tool written in Fortran with functionality mostly related, but not limited to, wind tunnel testing of aircraft.
- Stephen Kirkup sells and gives away Fortran codes for solving a range of physical problems by the Boundary Element Method. See the web site http://www.boundary-element-method.com.
- Here are three Makefile builders, one a perl or shell script, and the other two: a perl program, also a perl program.
- FMZM90 (related to FMLIB), provided by David Smith of Loyola Marymount University, is a Fortran-90 module that defines three derived types: multiple-precision real, multiple-precision integer, and multiple-precision complex. Interfaces are provided so that a program can declare variables to be multiple-precision types and then write the code for multiple-precision operations using normal Fortran syntax.
- MarshallSoft Computing offers “SMTP Email Library for Fortran” (SEE4F), which allows the ABSOFT Fortran programmer to send email including MIME attachments. SEE4F is marketed as shareware ($95).
