[scilab-Users] gateway fortran cpp

[Pedro Ledoux]

about Fortran for which and why are you using it? I`ve wrked as Fortran progeamer to a geologist.
I was able to make the main program in C which could call Fortran functions using the compilers gcc and
Open64.

Assunto: [scilab-Users] gateway fortran cpp


Hello,

I'm currently creating a toolbox that contains c++ and fortran files. As I handle c++ objects, it's more convenient for me to use c++ files in my gateway. Thus, for the compilation in scilab, I just need a header where i summerize all my functions as follows :

extern "C"{
int func1(char *fname)
int func2(char *fname)
...
} "

When those functions "func1", "func2" are linked to the c++ original code, the compilation in scilab works perfectly (builder and loader).
However, when those functions are linked to the fortran original code (which means that in my gateway file, I call a fortran function with "F2C"), the compilation in scilab doesn't work and i get the following error while I'm trying to execute the loader (the builder passes) :

addinter(libsplspcgateway_path + filesep() + 'libsplspcgateway' + getdynlibext(), 'libsplspcgateway', list_functions);
                                                                                                                      !--error 236 
addinter: The shared archive was not loaded: /home/.../sci_gateway/cpp//libsplspcgateway.so: undefined symbol: BAGMRES_

(where BAGMRES is the fortran function that I call with F2C in my gateway file in c++).

As I already succeeded to use fortran functions in gateway files in c, my question is the following :
Is it forbidden to call a fortran file in a gateway file in c++ and must I use inevitably a gateway file in c?
If on contrary it's possible, where could the problem come from?

I hope to be clear and I thank you for your help.
Best regards,
