Compile and Link Intel® Fortran and C Programs

Your application can contain both C and Fortran source files. If your main program is a Fortran source file (myprog.for) that calls a routine written in C (cfunc.c), you can use the following sequence of commands to build your application.

Linux

icx -c cfunc.c 
ifort -o myprog myprog.for cfunc.o

Windows

icx /c cfunc.c
ifort myprog.for cfunc.obj 
 /link /out:myprog.exe

The icpx command for Intel® C++ or the cl command (for Microsoft Visual C++) compiles cfunc.c. The -c or /c option specifies that the linker is not called. This command creates cfunc.o (Linux) or cfunc.obj (Windows).

The ifort command compiles myprog.for and links cfunc.o (Linux) or cfunc.obj (Windows) with the object file created from myprog.for to create the executable.

Additionally, on Linux systems, you may need to specify one or more of the following options:
