+ Build 3rd-parties {#build_upgrade_building_3rdparty}
+==============================================
+@tableofcontents
+
+On Windows, the easiest way to install third-party libraries is to download archive with pre-built binaries from https://opencascade.com/content/3rd-party-components.
+On Linux and OS X, it is recommended to use the version installed in the system natively.
+
+@section dev_guides__building_3rdparty_win_1 Windows
+
+This document presents guidelines for building third-party products used by Open CASCADE Technology (OCCT) and samples on Windows platform. It is assumed that you are already familiar with MS Visual Studio / Visual C++. 
+
+You need to use the same version of MS Visual Studio for building all third-party products and OCCT itself, in order to receive a consistent set of run-time binaries. 
+
+The links for downloading the third-party products are available at https://opencascade.com/content/3rd-party-components.
+
+There are two types of third-party products used  by OCCT: 
+
+* Mandatory  products: 
+	* Tcl/Tk 8.5 -- 8.6;
+	* FreeType 2.4.10 -- 2.5.3.
+* Optional  products:
+	* TBB 3.x -- 4.x;
+	* FreeImage 3.14.1 -- 3.16.0;
+	* VTK 6.1.0.
+
+It is recommended to create a separate new folder on your workstation, where you will unpack the downloaded archives of the third-party  products, and where you will build these products (for example, *c:\\occ3rdparty*). 
+
+Further in this document, this folder is referred to as *3rdparty*. 
+
+@subsection dev_guides__building_3rdparty_win_2 Tcl/Tk
+
+Tcl/Tk is required for DRAW test harness.
+
+**Installation from sources: Tcl**
+  
+Download the necessary archive from https://www.tcl.tk/software/tcltk/download.html and unpack it.
+  
+1. In the *win* sub-directory, edit file *buildall.vc.bat*:
+
+   * Edit the line "call ... vcvars32.bat" to have correct path to the version of Visual Studio to be used for building, for instance:
+
+         call "%VS80COMNTOOLS%\vsvars32.bat"
+
+     If you are building 64-bit version, set environment accordingly, e.g.:
+
+         call "%VS80COMNTOOLS%\..\..\VC\vcvarsall.bat" amd64
+     
+   * Define variable *INSTALLDIR* pointing to directory where Tcl/Tk will be installed, e.g.:
+
+         set INSTALLDIR=D:\OCCT\3rdparty\tcltk-86-32
+
+   * Add option *install* to the first command line calling *nmake*:
+
+         nmake -nologo -f makefile.vc release htmlhelp install %1
+
+   * Remove second call to *nmake* (building statically linked executable)
+
+2. Edit file *rules.vc* replacing line 
+
+       SUFX	    = tsgx
+
+   by
+
+       SUFX	    = sgx
+
+   This is to avoid extra prefix 't' in the library name, which is not recognized by default by OCCT build tools.
+
+
+3. By default, Tcl uses dynamic version of run-time library (MSVCRT), which must be installed on the system where Tcl will be used.
+   You may wish to link Tcl library with static version of run-time to avoid this dependency.
+   For that:
+
+   * Edit file *makefile.vc* replacing strings "crt = -MD" by "crt = -MT"
+
+   * Edit source file *tclMain.c* (located in folder *generic*) commenting out forward declaration of function *isatty()*.
+
+
+4. In the command prompt, run *buildall.vc.bat*
+
+   You might need to run this script twice to have *tclsh* executable installed; check subfolder *bin* of specified installation path to verify this.
+
+5. For convenience of use, we recommend making a copy of *tclsh* executable created in subfolder *bin* of *INSTALLDIR* and named with Tcl version number suffix, as *tclsh.exe* (with no suffix)
+
+       > cd D:\OCCT\3rdparty\tcltk-86-32\bin
+       > cp tclsh86.exe tclsh.exe
+
+**Installation from sources: Tk**
+  
+Download the necessary archive from https://www.tcl.tk/software/tcltk/download.html and unpack it.
+
+Apply the same steps as described for building Tcl above, with the same INSTALLDIR.
+Note that Tk produces its own executable, called *wish*. 
+
+You might need to edit default value of *TCLDIR* variable defined in *buildall.vc.bat* (should be not necessary if you unpack both Tcl and Tk sources in the same folder).
+
+@subsection dev_guides__building_3rdparty_win_2_2 FreeType
+
+FreeType is required for text display in a 3D viewer. You can download its sources from https://sourceforge.net/projects/freetype/files/
+
+### The building procedure
+
+1. Unpack the downloaded archive of FreeType product into the *3rdparty*  folder. As a result, you will get a folder named, for example, *3rdparty\\freetype-2.4.10*.  Further in this document, this folder is referred to as *freetype*. 
+   
+2. Open the solution file *freetype\\builds\\win32\\vc20xx\\freetype.sln*  in Visual Studio. Here *vc20xx* stands for your version of Visual Studio. 
+
+3. Select the configuration to build: either Debug or Release. 
+
+4. Build  the *freetype* project. 
+
+   As a result, you will get a  freetype import library (.lib) in the *freetype\\obj\\win32\\vc20xx*  folder.  
+
+
+5. If you build FreeType for a 64 bit platform, select in the main menu **Build - Configuration Manager**  and add *x64* platform to the solution configuration by copying the settings from Win32 platform: 
+
+   @figure{/build/build_3rdparty/images/3rdparty_image001.png}
+
+   Update the value of the Output File for  x64 configuration: 
+
+   @figure{/build/build_3rdparty/images/3rdparty_image003.png}
+
+   Build the *freetype* project. 
+
+   As a result, you will obtain a 64 bit import library (.lib) file in the *freetype\\x64\\vc20xx*  folder. 
+
+   To build FreeType as a dynamic library (.dll) follow steps 6, 7 and 8 of this procedure. 
+
+6. Open menu Project-> Properties-> Configuration  Properties-> General and change option **Configuration Type** to *Dynamic  Library (.dll)*. 
+7. Edit file *freetype\\include\\freetype\\config\\ftoption.h*:  
+  
+   in line 255, uncomment the definition of macro *FT_EXPORT* and change it as follows: 
+
+       #define FT_EXPORT(x)   __declspec(dllexport) x 
+
+8. Build  the *freetype* project. 
+
+   As a result, you will obtain the files of the import  library (.lib) and the dynamic library (.dll)   in folders <i>freetype  \\objs\\release</i> or <i>\\objs\\debug </i>. 
+   
+   If you build for a 64 bit platform, follow step 5 of the procedure. 
+
+   To facilitate the use of FreeType libraries in OCCT with minimal adjustment of build procedures, it is recommended to copy the include files and libraries of FreeType into a separate folder, named according to the pattern: *freetype-compiler-bitness-building mode*, where: 
+   * **compiler** is *vc8* or *vc9* or *vc10* or *vc11*; 
+   * **bitness**  is *32* or *64*;
+   * **building mode** is *opt* (for Release) or *deb* (for Debug). 
+    
+   The *include* subfolder should be copied as is, while libraries should be renamed to *freetype.lib* and *freetype.dll* (suffixes removed) and placed to subdirectories *lib *and  *bin*, respectively. If the Debug configuration is built, the Debug libraries should be put into subdirectories *libd* and *bind*. 
+
+
+@subsection dev_guides__building_3rdparty_win_3_1 TBB
+
+This third-party product is installed with binaries 
+from the archive that can be downloaded from https://github.com/intel/tbb.
+Go to the **Download** page, find the  release version you need  (e.g. *tbb30_018oss*) and pick the archive for Windows  platform. 
+
+Unpack the downloaded  archive of TBB product into the *3rdparty* folder. 
+
+Further in this document,  this folder is referred to as *tbb*. 
+
+@subsection dev_guides__building_3rdparty_win_3_3 FreeImage
+
+This third-party product should be built as a dynamically loadable library (.dll file). 
+You can download its sources from 
+https://sourceforge.net/projects/freeimage/files/Source%20Distribution/
+
+### The building procedure: 
+
+1. Unpack the  downloaded archive of FreeImage product into *3rdparty* folder. 
+  
+   As a result, you should have a folder named *3rdparty\\FreeImage*. 
+  
+   Rename it according to the rule: *freeimage-platform-compiler-building  mode*, where 
+   
+   * **platform**  is *win32* or *win64*; 
+   * **compiler**  is *vc8* or *vc9* or *vc10* or *vc11*; 
+   * **building  mode** is *opt* (for release) or *deb* (for debug) 
+
+   Further in this  document, this folder is referred to as *freeimage*. 
+
+2. Open the solution file *freeimage\\FreeImage.*.sln* in your Visual Studio. 
+  
+   If you use a Visual Studio version higher than VC++ 2008, apply conversion of the workspace. 
+   Such conversion should be suggested automatically by Visual  Studio. 
+    
+3. Select a  configuration to build. 
+
+   - Choose **Release**  if you are building Release binaries. 
+   - Choose **Debug** if you are building  Debug binaries. 
+
+   *Note:* 
+
+   If you want to  build a debug version of FreeImage binaries then you need to rename the following files in FreeImage and FreeimagePlus projects:
+   
+   Project -> Properties -> Configuration Properties -> Linker -> General -> Output File
+
+       FreeImage*d*.dll  to FreeImage.dll 
+       FreeImagePlus*d*.dll to FreeImagePlus.dll 
+
+   Project -> Properties -> Configuration Properties -> Linker -> Debugging-> Generate Program Database File
+
+       FreeImage*d*.pdb  to FreeImage.pdb 
+       FreeImagePlus*d*.pdb to FreeImagePlus.pdb 
+
+   Project -> Properties -> Configuration Properties -> Linker -> Advanced-Import Library
+
+       FreeImage*d*.lib  to FreeImage.lib 
+       FreeImagePlus*d*.lib  to FreeImagePlus.lib 
+
+   Project -> Properties -> Configuration Properties -> Build Events -> Post -> Build Event -> Command Line 
+
+       FreeImage*d*.dll     to FreeImage.dll 
+       FreeImage*d*.lib     to FreeImage.lib 
+       FreeImagePlus*d*.dll to FreeImagePlus.dll 
+       FreeImagePlus*d*.lib to FreeImagePlus.lib 
+
+   Additionally, rename in project FreeImagePlus 
+   
+   Project -> Properties -> Configuration  Properties -> Linker -> Input -> Additional Dependencies 
+
+       from FreeImage*d*.lib to FreeImage.lib 
+
+4. Select a platform to build. 
+
+   - Choose *Win32* if you are building for a 32 bit platform. 
+   - Choose *x64* if you are building for a 64 bit platform. 
+
+5. Start the building process. 
+
+   As a result, you should have the  library files of FreeImage product  in *freeimage\\Dist* folder (*FreeImage.dll* and *FreeImage.lib*) and in *freeimage\\Wrapper\\FreeImagePlus\\dist* folder (*FreeImagePlus.dll* and *FreeImagePlus.lib*).
+
+@subsection dev_guides__building_3rdparty_win_3_4 VTK
+
+VTK is an open-source, freely available software system for 3D computer graphics, image processing and visualization. VTK Integration Services component provides adaptation functionality for visualization of OCCT topological shapes by means of VTK library.
+
+### The building procedure:
+
+1. Download the necessary archive from https://www.vtk.org/VTK/resources/software.html and unpack it into *3rdparty* folder.
+
+   As a result, you will get a folder named, for example, <i>3rdparty\VTK-6.1.0.</i>
+
+   Further in this document, this folder is referred to as *VTK*.
+
+2. Use CMake to generate VS projects for building the library:
+   - Start CMake-GUI and select VTK folder as source path, and the folder of your choice for VS project and intermediate build data.
+   - Click **Configure**.
+   - Select the VS version to be used from the ones you have installed (we recommend using VS 2010) and the architecture (32 or 64-bit).
+   - Generate VS projects with default CMake options. The open solution *VTK.sln* will be generated in the build folder.
+
+3. Build project VTK in Release mode.

+  $ cd /dev/OCCT/opencascade-7.0.0
+  $ ./genproj cbp
+~~~~~
+
+The generated Code::Blocks project are placed into subfolder *adm/&lt;OS&gt;/cbp*.
+
+@note To use **genproj** and **genconf** tools you need to have Tcl installed and accessible by PATH.
+
+@subsubsection build_codeblocks_build Building

+
+@subsection build_occt_genproj Building with Genproj tool
+
+This page describes steps to build OCCT libraries from a complete source archive on Windows with <b>MS Visual C++</b> using projects generated by **genproj** tool. 
+It is an alternative to use of CMake build system (see @ref build_occt_win_cmake).
+
+**genproj** is a legacy tool (originated from command "wgenproj" in WOK) for generation of Visual Studio, Code.Blocks, and XCode project files used for building Open CASCADE Technology.
+These project files are placed inside OCCT directory (in *adm* subfolder) and use relative paths, thus can be moved together with sources.
+
+The project files included in official distribution of OCCT are generated by this tool.
+If you have official distribution with project files included, you can use them directly without a need to call **genproj**.
+
+@subsubsection build_msvc_3rdparty Third-party libraries
+
+Before building OCCT, make sure to have all the required third-party libraries installed.
+
+The easiest way to install third-party libraries is to download archive with pre-built binaries, corresponding to version of Visual Studio you are using, from https://opencascade.com/content/3rd-party-components.
+
+You can also build third-party libraries from their sources, see @ref build_upgrade_building_3rdparty for instructions.
+
+@subsubsection build_msvc_conf Configuration
+
+If you have Visual Studio projects already available (pre-installed or generated), you can edit file *custom.bat* manually to adjust the environment:
+
+* *VCVER* -- specification of format of project files, defining also version of Visual Studio to be used, and default name of the sub-folder for binaries:
+
+| VCVER     | Visual Studio version | Windows Platform                 | Binaries folder name |
+|-----------|-----------------------|----------------------------------|----------------------|
