Building OCCT from sources

In order to build OCCT libraries from these sources for use in your program, you need to:

1. Make sure you have all required third-party libraries installed (check software requirements in Overview).

   See the following documents for short guide to installation of third-party libraries on different platforms:

   • Building 3rd-party libraries on Windows
   • Building 3rd-party libraries on Linux
   • Building 3rd-party libraries on MacOS X

2. If you use bare OCCT sources from Git repository or made some changes affecting CDL files or dependencies of OCCT toolkits, you need to update header files generated from CDL, and regenerate build scripts for your environment using WOK. See Using WOK for details.

   Skip to step 3 if you use complete source package (e.g. official OCCT release) without changes in CDL.

3. Build using your preferred build tool.
   • Building on Linux with Autotools
   • Building with CMake (cross-platform)
   • Building on Mac OS X with Code::Blocks
   • Building on Windows with MS Visual Studio
   • Building on Mac OS X with Xcode
