# build, test, install eckit # Note the use of ecbuild in place of cmake # If no write permission in /usr/local, add -DCMAKE_INSTALL_PREFIX=$HOME/tools # to the ecbuild command and omit the :code:`sudo` in the :code:`make install`. Git checkout 0.23.0 # check out the most recent public release # create the build directory # create the eckit clone cd $HOME/projects Have been cloned from GitHub, compiled, and included in the JEDIĮcbuild does enforce the restriction recommended above on building your project outside of theĪs before, the steps shown in this section are only necessary if you are working outside theįor all systems, you need to have CMake, eigen3 installed before installing ecbuild. In particular, public releases from these repositories
#CMAKE COMMANDS SOFTWARE#
The JEDI software stack links directly to the public ecbuild, eckit, and fckit GitHub repositories In particular, the -trace and -debug-output options show every line of every script file that is executed while cmake is running. DCMAKE_Fortran_COMPILER = $CMP_ROOT/gfortran $HOME/projects/my_projectĬMake also has tools that are useful for debugging. CMP_ROOT =/usr/local/binĬmake -DCMAKE_C_COMPILER = $CMP_ROOT/gcc \
#CMAKE COMMANDS CODE#
Let’s say that you want to install in your home directory in the path $HOME/tools.Ĭmake -DCMAKE_C_COMPILER =/usr/local/bin/gcc $HOME/projects/my_project # C codeĬmake -DCMAKE_CXX_COMPILER =/usr/local/bin/g++ $HOME/projects/my_project # C++ codeĬmake -DCMAKE_Fortran_COMPILER =/usr/local/bin/gfortran $HOME/projects/my_project # Fortran code # Note that combinations of these can be issued with one CMake command if you # have a mix of source code languages. However, if you don’t have write permission to /usr/local, then you will need this control Which is used to specify where the programs and scripts are to be installed. This list is extensive, and probably the most relevant is If you build in a separate directory, one simple remove command will clean up the entireīuild area (without danger of removing source files) and keep the source git repositoryĬlear of extra files that you do not want to check into the repository.ĬMake provides many controls which are enabled through specifying the -D command line option. Generated make files, and additional CMake configuration and log files. The directory where the source code lives.ĬMake does not restrict you to do this, but doing so will keep the source directories freeįrom all of the clutter that the build process produces such as object files, the It is highly recommended that you build your code in a directory that is separate from This step is only necessary if you are working outside theįor the Mac, use homebrew to install CMake. Documentation andĭownloads are available at the CMake website.
The CMake developers provide a single package for CMake and CTest. To convert strings and arrays between Fortran and C/C++, and extending the unit test

Along with ecbuild we are using two ECMWF libraries calledĮckit is a C++ library that provides utilities including logging, MPI, configurationįile (JSON, YAML) parsing and math functions.įckit is a Fortran tool kit that provides similar utilities as eckit, plus helper functions
More toward performance benchmarking and verifying functionality on HPC systems.Įcbuild is a set of CMake macros provided by theĮCMWF that assist with the specification of the manufacturing processes. We may need to go beyond CTest to address our large scale system testing that is geared This system is well suited for short, fast running tests that tend to be in the unit Make files it generates, for compiling and linking your source code.ĬMake is in widespread use and the CMake website includesĭocumentation and tutorials to help you get started.ĬTest is the part of CMake that handles testing your code.ĬTest allows for an easy way to run your newly built programs with various argumentĪnd option settings, and then check the results against expected output.
