python-fortran

1. Create fortran file.

2. Compile fortran file like, for example, "gfortran -shared -fPIC -g -o add.so add.f90" Description previous command: gfortran == call compiler -shared == flag determined a type of generating lib -fPIC == flag that means "Generate position-independent code (PIC)" -g ==
   -o == flag determaned to create object file with extension ".o" add.so == creating file add.f90 == source file (file with source code)

3. Use in the terminal a command like "nm -ao add.so | grep test" Description: nm == Linux command printed the information about binary files -ao ==
   add.so == name of binary file grep == search test == name of my test fortran function As a result you'll see the name of your function in the generated file, and it gives something like:

add.so: 0000000000000f8e - 01 0000 FUN test add.so: 0000000000000f8e T test

In python file I called fortran function like "test_(variable_name, variable_name)".

4. Import .so file into python code.

5. Run python code.
