FORCES library
This is the FORTRAN library for Computational Environmental Systems of the
Department Computational Hydrosystems
Helmholtz Centre for Environmental Research - UFZ
Permoserstr. 15
04318 Leipzig, Germany
It is a lightweight fork of the jams_fortran library maintained by Matthias Cuntz et al: https://github.com/mcuntz/jams_fortran
The jams_fortran library was formerly developed at the CHS department at the UFZ and is now released under the MIT license.
Using FORCES with your Fortran program
Let's assume, you want to write a fortran program using forces, like this example test.f90:
program test
use mo_message, only : message
implicit none
call message("This is working!")
end program testYou should create a minimal CMakeLists.txt file next to the test.f90 file like this:
cmake_minimum_required(VERSION 3.14 FATAL_ERROR)
# get CPM (package manager)
set(CPM_DOWNLOAD_LOCATION "${CMAKE_BINARY_DIR}/cmake/CPM_0.35.0.cmake")
file(DOWNLOAD https://github.com/cpm-cmake/CPM.cmake/releases/download/v0.35.0/CPM.cmake ${CPM_DOWNLOAD_LOCATION})
include(${CPM_DOWNLOAD_LOCATION})
# create project
project(MyProject LANGUAGES Fortran)
# add executable
add_executable(test test.f90)
# add FORCES dependency
CPMAddPackage("https://git.ufz.de/chs/forces.git@0.3.1")
# link dependencies
target_link_libraries(test forces)There, CPM (the cmake package manager) is downloaded on the fly and used to get FORCES to be able to link against it.
Afterwards you only need to do the following to configure, compile and execute your program:
cmake -B build
cmake --build build --parallel
./build/testAnd it will happily write:
This is working!For a more complex project, prepared for unit-tests, documentation and modules, have a look at the Fortran Template.
