Building 3rd-party libraries on MacOS X {#occt_dev_guides__building_3rdparty_osx}
==============================================
@tableofcontents
@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 http://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;
* gl2ps 1.3.5 - 1.3.8;
* 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 http://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 http://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 http://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 http://threadingbuildingblocks.org/.
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_2 gl2ps 1.3.5
Download the necessary archive from http://geuz.org/gl2ps/ and unpack it.
1. Install or build cmake product from the source file.
2. Start cmake in GUI mode with the directory, where the source files of *fl2ps* are located:
ccmake GL2PS_SRC_DIR
* Press <i>[c]</i> to make the initial configuration;
* Define the necessary options in *CMAKE_INSTALL_PREFIX*;
* Press <i>[c]</i> to make the final configuration;
* Press <i>[g]</i> to generate Makefile and exit.
or just run the following command:
cmake –DCMAKE_INSTALL_PREFIX=GL2PS_INSTALL_DIR –DCMAKE_BUILD_TYPE=Release
3. Start the building of gl2ps
make
4. Start the installation of gl2ps. Binaries will be installed according to the *CMAKE_INSTALL_PREFIX* option
make install
@subsection dev_guides__building_3rdparty_osx_3_3 FreeImage 3.14.1 or 3.15.x
Download the necessary archive from
http://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
(http://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
