The Fortran Wiki has pages for each of the standards , listing their features, and it also has external links to summaries:. So in my view not obsolescent at all. I think you have misunderstood. The Fortran Standard marks as obsolete assumed-length character functions, that is functions where the result is assumed length.

LibgfortranAbiCleanup ArrayDescriptorUpdate Tracking unreviewed patches GFortranScalarizer documents the scalarizer gfortran uses internally to translate array fortran statements into scalar code enclosed in a loop. There is documentation for released compilers, and also documentation for the latest snapshot from the development tree.

The manuals are re-generated nightly. Doxygen documentation of the compiler , points to the full Doxygen documentation, including sources, globals and symbols. Log out, log back in on your machine, and test your setup as per this article before compiling your own cases.

Download the "detailed" setup documents posted below for intructions on installing GFortran silently on multiple machines:. You will be prompted to select a location for the Program Files.

When the installation is complete, you will be advised to log out and log in to Windows to apply the changes to your environment.
