CMake is a cross-platform build system with many nice features. It generates platform specific build files, such as Makefiles or Visual Studio project files during configuration.
It supports multiple targets, e.g. out-of-tree configurations and builds (simply configure from multiple build directories).
To add new files to be compiled, you will need to edit one of the following files
oofem/src/oofemlib/CMakeLists.txt oofem/src/sm/CMakeLists.txt oofem/src/fm/CMakeLists.txt oofem/src/tm/CMakeLists.txt
Add new files to new lines which makes it less likely to conflict when merging code in git.
set (oofemlib_element element.C structuralelement.C nlstructuralelement.C my_new_element.C )
For more complex additions that require new configuration options, you will need to modify CMakeLists.txt in the root directory
If new tests files are added CMake will find them automatically, just re-run cmake from the build directory.
Install CMake from the package system of your choice. Create an out-of-tree build directory:
mkdir -p ~/build/debug/ cd ~/build/debug/ cmake ~/oofem/ make ctest
cmake you can use
ccmake which uses an ncurses interface, or
cmake-gui for a GUI.
Use the command
make help for a list of all targets.
To make configuration options, either use the
cmake-gui or supply additional commands directly
cmake -DCMAKE_CXX_FLAGS="-Werror" ~/oofem/
In order to use a different compiler you need to start a new clean configuration (from an empty directory) and supply the new compiler using
mkdir -p ~/build/clang/ cd ~/build/clang/ cmake -DCMAKE_CXX_COMPILER=clang++ ~/oofem/ make ctest
Note: After initial configuration, you cannot change compiler. If you install a new version of GCC, you will need to remove the build directory and do the configuration again. Just doing
make clean isn't enough.
* The build process usually hides the compiler command lines, to show them, use
$ make VERBOSE=1
Some useful options for ctest include running the tests in parallel;
ctest -j 4
and regex search for limiting the tests you wish to check (the following example runs cemhyd01.in and cemhyd02.in)
ctest -R cemhyd
and lastly a verbose option to see what went wrong
CPack allows you to make source and binary releases. You will first need to configure using
cmake (as detailed above). The following commands are executed from the build directory.
To generate a source package (which excludes .git/ and generated files) run
To generate a DEB, RPM, ZIP binary packages of your currently configured directory, run
cpack -G DEB cpack -G RPM cpack -G ZIP ...
The KDevelop IDE has build in support for CMake projects (and GIT). It includes a graphical configuration of multiple targets. Simply choose to import a project, and select CMakeLists.txt from the source directory You can then open the configuration from the menu and make your choices:
With CMake, it is also possible to create shared library loadable as Python module. You need CMake version at least 2.8.8 and two additional cmake parameters (
-DUSE_PYTHON_BINDINGS=ON ). After standard
liboofem.so file is created in
build directory. From python it can be loaded and use like this:
import sys sys.path.append("/path/to/build/directory") # path where liboofem.so was created import liboofem a = liboofem.FloatArray(2) a = 15.0 a = 10.0 print a, a
To run the test suite, open the solution explorer in VS and “build” the
benchmarks targets to run through the test suite or benchmark suite respectively.
Note: The build types (debug, release) are handled internally by Visual Studio, so no configuration option for this is presented in CMake
Note: PETSc isn't easily built on windows, so support for parallel builds is still lacking
