Hi, i want to compile a code where fortran calls c . First I compiled C module ,it has pass by gcc. However, after generating .o file. I compiled C and fortran files together by intel fortran and it failed " undefined reference to 'vicerror'". vicerror is a function. I do not know why.
In your fortran code, don't you need to import the function, or the module that contains the function, that is causing the problem?
Something like:
modulename import
or possibly,
from modulename import functionname
