The library is written is FORTRAN 77 so it is very easy to CALL any subroutine from any FORTRAN code.
See how to build section
A call to the library is trivial. Make sure anyway that the variables are of the same type as defined in the detailled functions (subroutines).
To link any FORTRAN source code with the static library
you have to add at the end of the compilation command the option -Lpath
where path allows to locate the static library file and the option -loneradesp
(make sure the static lib name is liboneradesp.a)
If you have been using the Makefile to build the library then you have to add the proper
option depending on the compiler in order to force the compiler to add only a single underscore
to any subroutine. e.g. with g77 the option is -fno-second-underscore.
