Building with MS Visual C++ {#occt_dev_guides__building_msvc}
===========================

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

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 \ref occt_dev_guides__building_wok for instructions.

Before building OCCT, you need to install the required third-party libraries; see
paragraph 1 of \ref occt_dev_guides__building 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
   - <i>HAVE_*</i> - 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 <i>adm\\msvc\\vc[9-12]</i>.
   Binaries are produced in *win32* or *win64* folders.

3. Build with Visual Studio

To start DRAW, launch *draw.bat*.
