Procedure Pointers for gfortran

Google Summer of Code 2009 project

Student: Janus Weil

Mentor: Tobias Burnus

This page will be used to collect some useful information about this project, and to document my progress.


Summary

  • gfortran 4.3: Abstract interfaces and basic PROCEDURE declarations are available (no procedure pointers yet).

  • gfortran 4.4: Support for procedure pointers has been added. However, advanced features like procedure pointer components and procedure pointers as return values are not available yet.

  • gfortran 4.5: Full support for procedure pointers & procedure pointer components.

  • gfortran 4.6: Pointer initialization [F08] and a few bug fixes.

  • gfortran 4.7 & 4.8: Continued bug fixing.
