My source code is writen in fortran 90 and i complied the source code using command f90. How do you think I should complie my source file and build the shared library?
You probably need to figure this out: R doesn't explicitly support F90 on any platform. Two things are needed 1/ You have to be able to create a DLL that is properly linked to all the libraries it needs. Your compiler documentation should tell you how to do this.
That's the main step. Something like f90 -G -o aaa.so aaa.f might well do it (that's the Solaris syntax, BTW).
2/ The functions you call from R need to use the same calling conventions as the compilers used to compiler R. Duncan Murdoch has information at http://www.stats.uwo.ca/faculty/murdoch/software/compilingDLLs/ that describes how to do this for various compilers. Even if your's isn't on the list this might still be helpful
That's for Windows: he did say `Unix', unspecified.
