how to update a modified source file

[stoykov]

Hello,

If I need to modify some of the source files from /fem/src, how to update the changes in the libraries? One way is to run the configure file and reinstall the complete Elmer. But there should be a way to compile only the modified file and add it to the library /lib/libelmersolver.so.
Could someone tell me how to do it?

Regards,
Stan

Hi Stan

If you just want to compile a routine in src/modules then make a copy of the *.src file and compile it as in

Code: Select all

elmerf90 -o MyRoutine.so MyRoutine.f90 

(In Windows the suffix for the shared object is .dll). Then you can use this as a regular solver defined by the Procedure statement in the .sif file.

For library functionality I don't know of any way to avoid full compilation.

Thank you Peter,

yes, in the case of solver, I may compile and use it through the sif file.

But if I use the StressSolver and I need to change, for example, the SUBROUTINE Add2ndOrderTime, which is called from StreesSolver through Default2ndOrderTime, then I would need to compile SolverUtilis. But since it works with full compilation, it is ok.
