  • Various utilities to ease multiplatform development.


You can either use packaging scripts, which are stored in package/ subdirectory, or compile and install everything manually. Note that Doxygen documentation contains more comprehensive guide for building, packaging and crosscompiling.

Minimal dependencies

  • C++ compiler with good C++11 support. Compilers which are tested to have everything needed are GCC >= 4.7, Clang >= 3.1 and MSVC 2015. On Windows you can also use MinGW-w64. GCC 4.6, 4.5, 4.4 and MSVC 2013 support involves some ugly workarounds and thus is available only in compatibility branch.
  • CMake >= 2.8.12

Note that full feature set is available only on GCC >= 4.8.1 and Clang >= 3.1 and compatibility mode with reduced feature set must be enabled for other compilers.

Compilation, installation

The library can be built and installed using these four commands:

mkdir -p build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr .. && make
make install

Building and running unit tests

If you want to build also unit tests (which are not built by default), pass -DBUILD_TESTS=ON to CMake. Unit tests use Corrade's own TestSuite framework and can be run using

ctest --output-on-failure

in build directory. Everything should pass ;-)

Building documentation

The documentation is written in Doxygen (preferrably 1.8 with Markdown support, but older versions should do good job too) and additionally uses Graphviz for class diagrams. The documentation can be build by running


in root directory (i.e. where Doxyfile is). Resulting HTML documentation will be in build/doc/ directory.

Building examples

The library comes with handful of examples, contained in src/examples/ directory. Each example is thoroughly explained in documentation. The examples require Corrade to be installed and they are built separately:

mkdir -p build-examples
cd build-examples
cmake ../src/examples
