How to add a module

First using the correct fortran style, begin to write your module:

• Fortran style guidelines

Next we need to include it as a module for CMake. From your lungsim root directory, open CMakeLists.txt in the ./src/lib directory and insert the module into the list of source files by adding the following line in the appropriate place (source files are listed in alphabetical order under the LIB_SRCS variable, CMake will sort out the compilation order):

module_name.f90

Now we need to set up bindings. Create the following files, and fill in their contents appropriately (the details of which can be found in Wrapping a module):

./src/bindings/c/module_name.c

./src/bindings/c/module_name.f90

./src/bindings/c/module_name.h

./src/bindings/interface/module_name.i

and add the c bindings sources named after your module into the appropriate CMake variable (one of C_FORTRAN_LIB_SRCS, C_C_LIB_SRCS, C_LIB_HDRS) in:

./src/bindings/c/CMakeLists.txt

and lastly add the interface source named after your module into the CMake variable INTERFACE_SRCS in:

./src/bindings/python/CMakeLists.txt
