- 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.

+ Building 3rd-party libraries on Windows {#occt_dev_guides__building_3rdparty_windows}
+==============================================
+@tableofcontents
+
+@section dev_guides__building_3rdparty_win_1 Introduction
+
+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 on the web site of OPEN CASCADE SAS at https://www.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*. 
+
+@section dev_guides__building_3rdparty_win_2 Building Mandatory Third-party Products
+
+@subsection dev_guides__building_3rdparty_win_2_1 Tcl/Tk
+
+Tcl/Tk is required for DRAW test harness.
+
+@subsubsection dev_guides__building_3rdparty_win_2_1_1 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
+
+@subsubsection dev_guides__building_3rdparty_win_2_1_2 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{/dev_guides/building/3rdparty/images/3rdparty_image001.png}
+
+   Update the value of the Output File for  x64 configuration: 
+
+   @figure{/dev_guides/building/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).

+Building with CMake for Android {#occt_dev_guides__building_android}
+===================
+
+@tableofcontents
+
+This article describes the steps to build OCCT libraries for Android from a complete source package
+with GNU make (makefiles) on Windows 7 and Ubuntu 15.10.
+
+The steps on Windows and Ubuntu are similar. There is the only one difference: makefiles are built with mingw32-make
+on Windows and native GNU make on Ubuntu.
+
+Required tools (download and install if it is required):
+  - CMake v3.7+ https://www.cmake.org/cmake/resources/software.html
+  - Android NDK rev.10+ https://developer.android.com/tools/sdk/ndk/index.html
+  - GNU Make: MinGW v4.82+ for Windows (https://sourceforge.net/projects/mingw/files/), GNU Make 4.0 for Ubuntu.
+
+## Prerequisites
+
+In toolchain file <i>$CASROOT/adm/templates/android.toolchain.config.cmake</i>:
+
+  - Set CMAKE_ANDROID_NDK variable equal to your Android NDK path.
+  - Set CMAKE_ANDROID_STL_TYPE variable to specify which C++ standard library to use.
+
+The default value of CMAKE_ANDROID_STL_TYPE is <i>gnustl_shared</i> (GNU libstdc++ Shared)
+
+@figure{/dev_guides/building/android/images/android_image001.png}
+
+## Generation of makefiles using CMake GUI tool
+Run GUI tool provided by CMake: cmake-gui
+
+### Tools configuration
+  - Specify the root folder of OCCT (<i>$CASROOT</i>, which contains *CMakelists.txt* file) by clicking **Browse Source**.
+  - Specify the location (build folder) for Cmake generated project files by clicking **Browse Build**.
+
+@figure{/dev_guides/building/android/images/android_image002.png}
+
+Click **Configure** button. It opens the window with a drop-down list of generators supported by CMake project.
+
+Select "MinGW Makefiles" item from the list
+  - Choose "Specify toolchain file for cross-compiling"
+  - Click "Next"
+
+@figure{/dev_guides/building/android/images/android_image003.png}
+
+  - Specify a toolchain file at the next dialog by <i>android.toolchain.config.cmake</i> . It is contained by cross-compilation toolchain for CMake
+  - Click "Finish"
+@figure{/dev_guides/building/android/images/android_image004.png}
+
+If on Windows the message is appeared: "CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles"
+CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.",
+specify **CMAKE_MAKE_PROGRAM** to mingw32-make executable.
+@figure{/dev_guides/building/android/images/android_image005.png}
+
+### OCCT Configuration
+
+How to configure OCCT, see "OCCT Configuration" section of @ref occt_dev_guides__building_cmake "Building with CMake"
+
+### Generation of makefiles
+
+Click **Generate** button and wait until the generation process is finished. 
+Then makefiles will appear in the build folder (e.g. <i> D:/occt/build-android </i>).
+
+## Generation of makefiles using CMake from the command line
+
+Alternatively one may specify the values without a toolchain file:
+
+> cmake -G "MinGW Makefiles" -DCMAKE_SYSTEM_NAME=Android -DCMAKE_ANDROID_NDK=D:/DevTools/android-ndk-r13b -DCMAKE_ANDROID_STL_TYPE=gnustl_shared -DCMAKE_SYSTEM_VERSION=15 -DCMAKE_ANDROID_ARCH_ABI=armeabi-v7a -DCMAKE_MAKE_PROGRAM=D:/DevTools/MinGW/bin/mingw32-make.exe -D3RDPARTY_DIR=D:/occt-3rdparty D:/occt
+
+@figure{/dev_guides/building/android/images/android_image006.png}
+
+## Building makefiles of OCCT
+
+Open console and go to the build folder. Type "mingw32-make" (Windows) or "make" (Ubuntu) to start build process.
+
+> mingw32-make
+or
+> make
+
+
+Parallel building can be started with using **"-jN"** argument of "mingw32-make/make", where N is the number of building threads.
+
+> mingw32-make -j4
+or
+> make -j4
+
+## Install built OCCT libraries
+
+Type "mingw32-make/make" with argument "install" to place the libraries 
+to the install folder (see "OCCT Configuration" section of @ref occt_dev_guides__building_cmake "Building with CMake")
+
+> mingw32-make install
+or
+> make install

msv	068969acef	0031292: Data Exchange - SIGSEGV on reading STEP file with references to invalid entities Changes: - in StepData_StepReaderData::ReadEntity, make sure that entity handle is not null before calling IsKind() of it. - in StepData_StepReaderData::SetEntityNumbers, do not invert the sign of entity number of referenced parameter if the second pass is not required. Otherwise, the number -1 (obviously invalid) becomes 1 (invalid, but not obviously) without further correction of it. - in StepData_UndefinedEntity::ReadRecord, consider the case when the entity number is positive but refers to non-existing entity.

kgv	48839a4046	0031070: Configuration - fix building issues when using Emscripten toolchain Handled __EMSCRIPTEN__ macros to: - Workaround atomics (__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 is undefined, but GCC atomics are provided). - Suppress non-standard header <sys/signal.h> warning. - Return OSD_LinuxREDHAT. - Avoid inclusion of XLib headers. - Skip fontconfig library. - Enable EGL+GLES path (translated by Emscripten into WebGL). - Skip eglCreatePbufferSurface() not implemented by Emscripten EGL. Fixed Graphic3d_Vec4.hxx usage within Quantity_ColorRGBA.hxx. OpenGl_ShaderManager::defaultGlslVersion() now prefers GLSL 300 es when WebGL 2.0 is available, as there no any OpenGL ES greater than 3.0 emulation so far. Shaders_Declarations.glsl - added workaround for GLSL compilation on WebGL 1.0 by defining Light properties accessors as macros instead of functions ('[]' : Index expression must be constant). OpenGl_FrameBuffer::Init() - added workaround for initialization of GL_DEPTH24_STENCIL8 depth-stencil attachment on WebGL 1.0 + GL_WEBGL_depth_texture extension. OpenGl_Context::Vec4FromQuantityColor() now considers myIsSRgbActive flag to handle use case, when Immediate Layer is drawn directly into window buffer, which is not sRGB-ready. Added new sample - OCCT WebGL viewer.	2019-11-01 10:09:17 +03:00
