mbkumar / f90wrap_cmake_demo

Demo project to showcase integration of pip, CMake and f90wrap

Demo of pip, setuptools, CMake and f90wrap

Prerequisites

C and Fortran compilers. Tested with gcc suite. Some flags are specific to gcc suite.

Compilation of the code

pip install .

Note that there is a dot after install.

Testing the code

Unfortunately even though the code is correctly installed at the correct location, few issues are still pending.

import cylinder  # should work
import cylinder.cyl # will fail

Pending Issues

1. One of the intermediate library is not seamlessly loaded with out user intervention. Add the directory of installation to $LD_LIBRARY_PATH. The directory of the installation can be found from

python -c "import cylinder; print(cylinder.__path__)"

2. Slight modification of the f90wrap generated cyl.py is required. Open the cyl.py from the path identified in the previous step and change the line containing import _cyl to import cylinder._cyl as _cyl or from . import _cyl. Now both lines should work

import cylinder  # should work
import cylinder.cyl # should work
