-@section dev_guides__building_3rdparty_osx_1 Introduction
-
-This document presents additional guidelines for building third-party products
-used by Open CASCADE Technology and samples on Mac OS X platform (10.6.4 and later).
-
-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, which are necessary to build 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
-
-@section dev_guides__building_3rdparty_osx_2 Building Mandatory Third-party Products
-
-@subsection dev_guides__building_3rdparty_osx_2_1 Tcl/Tk 8.5
-
-Tcl/Tk is required for DRAW test harness. Version 8.5 or 8.6 can be used with OCCT.
-
-@subsubsection dev_guides__building_3rdparty_osx_2_1_2 Installation from sources: Tcl 8.5
-
-Download the necessary archive from https://www.tcl.tk/software/tcltk/download.html and unpack it.
-
-1. Enter the *macosx* sub-directory of the directory where the Tcl source files are located <i>(TCL_SRC_DIR)</i>.
-
- cd TCL_SRC_DIR/macosx
-
-2. Run the *configure* command
-
- configure --enable-gcc --enable-shared --enable-threads --prefix=TCL_INSTALL_DIR
-
- For a 64 bit platform also add <i>--enable-64bit</i> option to the command line.
-
-3. If the *configure* command has finished successfully, start the building process
-
- make
-
-4. If building is finished successfully, start the installation of Tcl.
- All binary and service files of the product will be copied to the directory defined by *TCL_INSTALL_DIR*.
-
- make install
-
-@subsubsection dev_guides__building_3rdparty_osx_2_1_3 Installation from sources: Tk 8.5
-
-Download the necessary archive from https://www.tcl.tk/software/tcltk/download.html and unpack it.
-
-1. Enter the *macosx* sub-directory of the directory where the source files of Tk are located <i>(TK_SRC_DIR)</i>.
-
- cd TK_SRC_DIR/macosx
-
-2. Run the *configure* command, where TCL_LIB_DIR is TCL_INSTALL_DIR/lib
-
- configure --enable-gcc --enable-shared --enable-threads --with-tcl=TCL_LIB_DIR --prefix=TK_INSTALL_DIR
-
- For a 64 bit platform also add <i>--enable-64bit</i> option to the command line.
-
-3. If the *configure* command has finished successfully, start the building process:
-
- make
-
-4. If the building has finished successfully, start the installation of Tk. All binary and service files of the product will be copied to the directory defined by *TK_INSTALL_DIR* (usually it is TCL_INSTALL_DIR)
-
- make install
-
-@subsection dev_guides__building_3rdparty_osx_2_2 FreeType 2.4.10
-
-FreeType is required for text display in the 3D viewer.
-
-Download the necessary archive from https://sourceforge.net/projects/freetype/files/ and unpack it.
-
-1. Enter the directory where the source files of FreeType are located <i>(FREETYPE_SRC_DIR)</i>.
-
- cd FREETYPE_SRC_DIR
-
-2. Run the *configure* command
-
- configure --prefix=FREETYPE_INSTALL_DIR
-
- For a 64 bit platform also add <i>CFLAGS='-m64 -fPIC' CPPFLAGS='-m64 -fPIC'</i> option to the command line.
-
-3. If the *configure* command has finished successfully, start the building process
-
- make
-
-4. If building has finished successfully, start the installation of FreeType.
- All binary and service files of the product will be copied to the directory defined by *FREETYPE_INSTALL_DIR*.
-
- make install
-
-@section dev_guides__building_3rdparty_osx_3 Building Optional Third-party Products
-
-@subsection dev_guides__building_3rdparty_osx_3_1 TBB 3.x or 4.x
-
-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 Mac OS X platform.
-To install, unpack the downloaded archive of TBB 3.0 product (*tbb30_018oss_osx.tgz*).
-
-@subsection dev_guides__building_3rdparty_osx_3_3 FreeImage 3.14.1 or 3.15.x
-
-Download the necessary archive from
-https://sourceforge.net/projects/freeimage/files/Source%20Distribution/
-and unpack it. The directory with unpacked sources is further referred to as *FREEIMAGE_SRC_DIR*.
-
-Note that for building FreeImage on Mac OS X 10.7 you should replace *Makefile.osx*
-in *FREEIMAGE_SRC_DIR* by the corrected file, which you can find in attachment to issue #22811 in OCCT Mantis bug tracker
-(https://tracker.dev.opencascade.org/file_download.php?file_id=6937&type=bug).
-
-1. If you build FreeImage 3.15.x you can skip this step.
- Modify <i>FREEIMAGE_SRC_DIR/Source/OpenEXR/Imath/ImathMatrix.h:</i>
-
- In line 60 insert the following:
-
- #include string.h
-
- Modify <i>FREEIMAGE_SRC_DIR/Source/FreeImage/PluginTARGA.cpp:</i>
-
- In line 320 replace:
-
- SwapShort(value);
-
- with:
-
- SwapShort(&value);
-
-2. Enter the directory where the source files of FreeImage are located <i>(FREEIMAGE_SRC_DIR)</i>.
-
- cd FREEIMAGE_SRC_DIR
-
-3. Run the building process
-
- make
-
-4. Run the installation process
-
- 1. If you have the permission to write into <i>/usr/local/include</i> and <i>/usr/local/lib</i> directories, run the following command:
-
- make install
-
- 2. If you do not have this permission, you need to modify file *FREEIMAGE_SRC_DIR/Makefile.osx*:
-
- Change line 49 from:
-
- PREFIX ?= /usr/local
-
- to:
-
- PREFIX ?= $(PREFIX)
-
- Change lines 65-69 from:
-
- install -d -m 755 -o root -g wheel $(INCDIR) $(INSTALLDIR)
- install -m 644 -o root -g wheel $(HEADER) $(INCDIR)
- install -m 644 -o root -g wheel $(SHAREDLIB) $(STATICLIB) $(INSTALLDIR)
- ranlib -sf $(INSTALLDIR)/$(STATICLIB)
- ln -sf $(SHAREDLIB) $(INSTALLDIR)/$(LIBNAME)
-
- to:
-
- install -d $(INCDIR) $(INSTALLDIR)
- install -m 755 $(HEADER) $(INCDIR)
- install -m 755 $(STATICLIB) $(INSTALLDIR)
- install -m 755 $(SHAREDLIB) $(INSTALLDIR)
- ln -sf $(SHAREDLIB) $(INSTALLDIR)/$(VERLIBNAME)
- ln -sf $(VERLIBNAME) $(INSTALLDIR)/$(LIBNAME)
-
- Then run the installation process by the following command:
-
- make PREFIX=FREEIMAGE_INSTALL_DIR install
-
-5. Clean temporary files
-
- make clean
