Prerequisites for OS X
SOFA requires at least GCC 4.8 or Clang 3.4. To make sure you have a correct version, execute the usual commands:
gcc --version clang --version
LLVM vs. GCC
The default compiler on MacOS is now LLVM (ie. clang). SOFA is compatible with Clang but if you want to use gcc/g++ instead it is necessary to tell CMake.
To change the default compiler, set
CMAKE_CXX_COMPILER in cmake. For example, to set the compiler to gcc through command line :
cmake -DCMAKE_C_COMPILER=llvm-gcc -DCMAKE_CXX_COMPILER=llvm-g++ ... You may require to regenerate the project for the changes to take effect.
WARNING: if you are on MacOS 10.8 Mountain Lion, gcc is an alias of clang. To really use gcc, use
CMake: Makefile generator
SOFA requires at least CMake 3.1. To install CMake, download the latest DMG package from their download page.
[optional] Ninja: build system
Ninja is an alternative to Make. It has a better handling of incremental builds.
brew install ninja
To use Ninja, do not forget to set the CMake generator to "Codeblocks – Ninja" (as explained in Generate a Makefile with CMake).
To compile SOFA, you need to install several dependencies using Homebrew
Qt (>= 5.5.0)
We recommend to install Qt in your user directory with the unified installer.
Boost (>= 1.54.0)
brew install boost
Additional libraries: libPNG, libTIFF, libJPEG, Zlib, Glew
brew install libpng libjpeg libtiff glew
Building on OS X
Setting up your source and build directories
To set up clean repositories, we propose to arrange the SOFA directories as follows:
First, download the sources from Git repository:
Get the current stable version on the v18.06 branch:
git clone -b v18.06 https://github.com/sofa-framework/sofa.git sofa/src
OR get the development unstable version on the master branch:
git clone -b master https://github.com/sofa-framework/sofa.git sofa/src
Generate a Makefile with CMake
If you didn’t do it yet, create a build/ folder respecting directories arrangement.
Run CMake-GUI and set source folder with Browse Source and build folder with Browse Build.
Next, run Configure. A popup window will ask you to specify the generator for the project.
If you installed Ninja, select "Codeblocks – Ninja". Otherwise, select "Codeblocks – Makefile".
Keep "Use default native compilers" selected, and press "Finish".
You need to run Configure twice, since SOFA requires two passes to manage the module dependencies. You can then customize your version of SOFA, activate or deactivate plugins and functionalities.
When you are ready, press Generate. This will create your Visual Studio solution or your makefiles if you chose another generator.
Qt detection errors
To solve Qt detection errors, click on Add Entry and add
CMAKE_PREFIX_PATH with path
/Users/YOUR_USERNAME/Qt/QT_VERSION/COMPILER matching your Qt architecture.
A further dev warning may appear:
CMake Warning (dev) at YOUR_QT_PATH/lib/cmake/Qt5Core/Qt5CoreMacros.cmake:224 (configure_file): configure_file called with unknown argument(s): COPY_ONLY Call Stack (most recent call first): applications/projects/Modeler/exec/CMakeLists.txt:14 (qt5_add_resources)
This is just a typo with Qt5CoreMacros.cmake file. It uses COPY_ONLY instead of COPYONLY. Simply edit your Qt5CoreMacros.cmake, replace COPY_ONLY with COPYONLY and Configure again.
To compile in the terminal, go to your build directory and run
ninja depending on the generator you chose during CMake configuration.
Do not forget the
-j option to use all your CPU cores.
Time for a coffee!
Setting up QtCreator
The following instructions assume that you have set up two build directories as explained in the previous section.
In QtCreator, open project CMakeLists.txt. Choose build-release as build directory, then click on Finish. QtCreator is ready to compile, and the build configuration is named "all", though it corresponds to a Release.
Click on the Project button in the left, then rename the configuration from "all" to "Release".
Now click on add/Build to create a new configuration called "Debug". Choose build-debug as build directory and run Cmake. If you set the -G "CodeBlocks – Unix Makefiles" option in the cmake command line discussed in the previous section, you do not even need to run CMake.
You can now switch between Debug and Release in QtCreator. The compilation will be done using ccache (if installed). You can check this by setting VERBOSE=1 as additional argument to Make in the Projects tab on the left. Moreover, you probably want to run parallel compilations by setting -j10 for instance, for 10 parallel compilations, as additional argument to Make. Ubuntu 14.04: default qtcreator cmake plugin is bugged, but you can easily install qtcreator 3.1.1 from this non-official repository  (Warning, it is using qt4 rather than qt5).
