Building with MS Visual C++

This file describes steps to build OCCT libraries from a complete source archive on Windows with MS Visual C++.

If you build OCCT from bare sources (as in Git repository) or do some changes affecting CDL files, you need to use WOK to re-generate header files and build scripts / projects. See Using WOK for instructions.

Before building OCCT, you need to install the required third-party libraries; see paragraph 1 of Building OCCT from sources for instructions.

1. Edit file custom.bat to define the environment:
   • VCVER - version of Visual Studio (vc8, vc9, vc10, vc11 or vc12), and relevant VCVARS path
   • ARCH - architecture (32 or 64), affects only PATH variable for execution
   • HAVE_* - flags to enable or disable use of optional third-party products
   • CSF_OPT_* - paths to search for includes and binaries of all used third-party products

2. Launch msvc.bat to start Visual Studio with all necessary environment variables defined.

   Note: the MSVC project files are located in folders adm\msvc\vc[9-12]. Binaries are produced in win32 or win64 folders.

3. Build with Visual Studio

   Note: If VTK was not installed on you computer and you are not interested in usage of OCCT VTK Integration Services (VIS) component you should exclude TKIVtk and TKIVtkDraw projects from process of compilation in the main menu Build / Configuration Manager.

To start DRAW, launch draw.bat.
