See the CGoGN Web site for more informations.

We provide:

• CGoGN the core library
• tutorials and examples
• SCHNApps an integrated interface with plugin system.

CGoGN and SCHNApps are compatible with Linux, Mac and Windows The usage of C++11 enforce the usage of recent compilers (g++4.8, clang3.0, cl18)

Linux

Dependencies

• install for following package cmake cmake-curses-gui cmake-qt-gui libXi-dev libXmu-dev libglew-dev zlib1g-dev uuid-dev libgsl0-dev libsuitesparse-dev python27
• for Qt4: libqt4-dev qt4-dev-tools qtcreator
• for Qt5: qt5-default qtbase5-dev-tools qtcreator

Supported compilers: g++ 4.8 or greater

Compiling

• Launch cmake in a build directory with path to the CGoGN root directory as source parameter
• If directory name finish by 'Debug' compilation is done in Debug mode, else in Release mode
• Go in build directory and make (-j4 in your machine is 4 core)

CMake options (using gui or ccmake)

• CGoGN_WITH_ASSIMP: build CGoGN with Assimp (or not)
• CGoGN_WITH_ZINRI: build CGoGN with Zinri lib (or not)
• CGoGN_WITH_QT: build CGoGN with Qt (or not)
• CGoGN_DESIRED_QT_VERSION: Choose 4 or 5"
• CGoGN_WITH_GLEWMX: use (or not) multi-contex GLEW (for VRJuggler).
• CGoGN_USE_OGL_CORE_PROFILE: use (or not) OpenGL 3.3 core profile.
• CGoGN_COMPILE_EXAMPLES: compile the examples.
• CGoGN_COMPILE_TUTOS: compile the tutorials.
• CGoGN_COMPILE_TESTS: compile the tests.
• CGoGN_COMPILE_BENCHES: compile the benches.
• CGoGN_COMPILE_SANDBOX: compile all in sandbox
• CGoGN_ONELIB: build CGoGN in one lib instead of 4 separated libs

By default libraries are generated in dynamic version.

You can ideally do the same with QtCreator

Same compilation system for SCHNApps.

MacOS

Dependencies

• XCode and command line tools.
• Qt4 or Qt5 and QtCreator (native or with homebrew)
• cmake (native or with homebrew)
• install with homebrew : lzlib, glew, suite-sparse (you must first add the homebrew/science repository with the following command : brew tap homebrew/science)
• for macport user installation of suite sparse must be done with "+metis" (sudo port install SuiteSparse +metis)

Supported compilers: clang 3.0 or greater

Compiling

As on linux

CMake Qt detection problem

If Qt is not found, add path to Qt to CMAKE_PREFIX_PATH variable.

Executables generation

For best system compatibility executables are generated in bin/Release/Contents/MacOS

Window

Dependencies

• install (or compile) Qt (choose 32/64 bits)
• install python 2.7 (choose 32/64 bits) (Needed for SCHNApps)
• Other Windows dependencies are furnished at http://cgogn.unistra.fr/Dependencies/

Supported compilers: Visual C++ 2013 (12.0) or greater

Environment variables

• set PYTHON_PATH to your python installation directory
• set PYTHON_LIB to your python installation directory + \lib
• add xxx\windows_dependencies\lib to PATH
• add path to bin of Qt to PATH

Compiling

• Use CMake with a build directory and path to the CGoGN root directory as source parameter
• for CMake options see Linux compiling
• generated visual solution (choose right compiler type)
• launch Visual Studio !
• build solution after choosing Debug/Release

CMake Qt detection problem

If Qt is not found set the QT_QMAKE_EXECUTABLE cmake variable.

DLL/Executables generation

To avoid dll loading problem, all dll and executable (even SCHNApps) are generated in bin/Release or bin/Debug of CGoGN root directory.

Same compilation system for SCHNApps.

Compiling simple application

To compile a Qt application using Qt, you just need to include apps_cmake.txt after setting the CGoGN_ROOT_DIR variable. See example provided in apps_cmake.txt comments.
