Modernizing Old Fortran in Fortran Wiki. Fortran 90 Practical Exercises. L-BFGS. Software for Large-scale Unconstrained Optimization L-BFGS is a limited-memory quasi-Newton code for unconstrained optimization. The code has been developed at the Optimization Center, a joint venture of Argonne National Laboratory and Northwestern University. Downloading and Installing L-BFGS You are welcome to grab the full Unix distribution, containing source code, makefile, and user guide. This software is freely available for educational or commercial purposes. Save the gz file in a fresh subdirectory on your system. Gunzip lbfgs_um.tar.gz to produce a file lbfgs_um.tar. Tar -xvf lbfgs_um.tar to have the source code, makefile and user guide put in the current directory.
Authors Jorge Nocedal References J. . [ NEOS Server ] Installing Fortran Compiler. From CodeBlocks Attaching the compiler framework To attach the GNU Fortran 77 Compiler (G77) the following steps are required: Make a copy of the GNU GCC compiler as follows: 1.) 2.) 3.) Setup the compiler as follows: 1.) 2.) 3.) Important: Make sure the path environment is setup to really point a path that contains the Fortran compiler suite. Adding new Fortran file type It makes sense to add a new "Fortran Sources" filetype to have the Fortran source code files being seperated.
Goto menu "Project" -> "Project tree" -> "Edit file types categories" Click on "Add" to add a new type of files Select "Fortran Sources" as group name Enter the following in the file-mask (without quotation marks): "*.f;*.f77;*.cmn;*.inc;" Click OK to close the dialog. For your interest: "*.f;*.f77" are normally the default extensions for source code files, "*.cmn" is the extension for Fortran common-blocks and "*.inc" if often used as include file with e.g. variable declarations.
