Install multiple versions with different compile options

[wulle]

Hello,

I would like to install multiple versions of ParFeap (I have different configurations of PETSc, so I would like to have one FEAP executable for each architecture).
If we assume, that I would also like to change compiler options/optimization flags for the different versions, two questions come to my mind:

• To which extend do I have to clean the FEAPHOME directory before compiling another version? Is it enough to use make clean or do I also have to clean all archives for my compiler options to have any effect?
• Does ParFEAP or FEAP link to any libraries dynamically or does the feap executable contain anything it needs to run (neglecting system-wide libraries)

Best Regards
wulle

If you are changing compilers you will need to run

Code: [Select]

make clean followed by

Code: [Select]

make aclean.
The archive is the only FEAP library that is used and it is a static library.

To see what system level (shared) libraries are being pulled run

Code: [Select]

ldd parfeap/feap on Linux based systems or

Code: [Select]

otool -L parfeap/feap on Mac systems
