After upgrading to a newer version, follow these next steps:
- If the new version is a major upgrade (for example, from 2.20 to 2.21), recompile the sources
and form files. While recompilation is not needed when migrating to maintenance release versions
(for example, from 2.21.01 to 2.21.02), it is recommended to benefit from potential p-code
optimizations.
- If required, you may need to recreate the C Extension libraries. C extension libraries must be
provided as dynamically loadable modules and thus should not required a rebuild.
However, if the C Extension API header files have changed, consider recompiling your
C sources. Check FGLDIR/include/f2c for C
Extension API header file changes.
