Using Intel's ifort on windows: How do I tell specify that the main file is not written in Fortran?
To use Intel's ifort
compiler on Windows and specify that the main file (entry point) of your program is not written in Fortran, you can follow these steps:
Compile the Main File Separately: Compile the non-Fortran main file (e.g., written in C, C++, or any other language) separately using the appropriate compiler (e.g.,
gcc
,clang
, orcl
for Microsoft Visual C++). This will generate an object file (e.g.,main.obj
).Compile the Fortran Files: Use the
ifort
compiler to compile your Fortran files as usual, including any Fortran modules, subroutines, or functions. This will generate Fortran object files (e.g.,file1.obj
,file2.obj
, etc.).Link the Object Files: Finally, link all the object files (Fortran and non-Fortran) together using the
ifort
linker. Specify the main object file (main.obj
) as the entry point for the program. Theifort
linker will then create the final executable.
Here's an example of the compilation and linking process:
bash# Compile the non-Fortran main file separately
gcc -c main.c -o main.obj
# Compile the Fortran files
ifort -c file1.f90 -o file1.obj
ifort -c file2.f90 -o file2.obj
# ...
# Link all the object files together
ifort main.obj file1.obj file2.obj -o program.exe
Replace main.c
, file1.f90
, file2.f90
, and program.exe
with the actual file names for your program. Adjust the compiler commands (gcc
, ifort
) if you are using a different compiler.
By compiling the main file separately and specifying it as the entry point during the linking step, you can combine Fortran and non-Fortran code into a single executable using Intel's ifort
compiler on Windows.
