Building 3rd-party libraries on MacOS X

@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.org/getocc/require/.

There are two types of third-party products, which are necessary to build OCCT:

• Mandatory products: Tcl 8.5, Tk 8.5, FreeType 2.4.10
• Optional products: TBB 3.x or 4.x, gl2ps 1.3.5, FreeImage 3.14.1 or 3.15.x

@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_1 Installation from binaries

It is possible to download ready-to-install binaries from http://www.activestate.com/activetcl/downloads

• 1. Download the disk image to some TCL_DOWNLOAD_DIR.
• 2. Open in Finder the directory TCL_DOWNLOAD_DIR.
• 3. Open disk image and follow instructions.

@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 source files of Tcl are located (TCL_SRC_DIR).

@verbatim cd TCL_SRC_DIR/macosx
@endverbatim

• 2. Run the configure command

@verbatim configure --enable-gcc --enable-shared --enable-threads --prefix=TCL_INSTALL_DIR
@endverbatim

For a 64 bit platform also add --enable-64bit option to the command line.

• 3. If the configure command has finished successfully, start the building process

@verbatim make
@endverbatim

• 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

@verbatim make install
@endverbatim

@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 (TK_SRC_DIR).

@verbatim cd TK_SRC_DIR/macosx
@endverbatim

• 2. Run the configure command, where TCL_LIB_DIR is TCL_INSTALL_DIR/lib

@verbatim configure --enable-gcc --enable-shared --enable-threads --with-tcl=TCL_LIB_DIR --prefix=TK_INSTALL_DIR
@endverbatim

where TCL_LIB_DIR is TCL_INSTALL_DIR/lib. For a 64 bit platform also add --enable-64bit option to the command line.

• 3. If the configure command has finished successfully, start the building process

@verbatim make
@endverbatim

• 4. If 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 TK_INSTALL_DIR is TCL_INSTALL_DIR)

@verbatim make install
@endverbatim

@subsection dev_guides__building_3rdparty_osx_2_2 FreeType 2.4.10

FreeType is required for display of text in 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 (FREETYPE_SRC_DIR).

@verbatim cd FREETYPE_SRC_DIR
@endverbatim

• 2. Run the configure command

@verbatim configure --prefix=FREETYPE_INSTALL_DIR
@endverbatim

For a 64 bit platform also add CFLAGS='-m64 -fPIC' CPPFLAGS='-m64 -fPIC' option to the command line.

• 3. If the configure command has finished successfully, start the building process

@verbatim make
@endverbatim

• 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

@verbatim make install
@endverbatim

@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 "Downloads / Commercial Aligned Release", 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 source file.
• 2. Start cmake in GUI mode with the directory where the source files of fl2ps are located @verbatim ccmake GL2PS_SRC_DIR
     @endverbatim
  • 2.1. Press [c] to make the initial configuration
  • 2.2. Define the necessary options CMAKE_INSTALL_PREFIX
  • 2.3. Press [c] to make the final configuration
  • 2.4. Press [g] to generate Makefile and exit

or just run the following command:

@verbatim cmake –DCMAKE_INSTALL_PREFIX=GL2PS_INSTALL_DIR –DCMAKE_BUILD_TYPE=Release
@endverbatim

• 3. Start building of gl2ps

@verbatim make
@endverbatim

• 4. Start the installation of gl2ps. Binaries will be installed according to the CMAKE_INSTALL_PREFIX option

@verbatim make install
@endverbatim

@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 corrected one 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) or elsewhere.

• 1.If you are building FreeImage 3.15.x you can skip this step. Modify FREEIMAGE_SRC_DIR/Source/OpenEXR/Imath/ImathMatrix.h:

In line 60 insert the following:

@verbatim #include string.h @endverbatim

Modify FREEIMAGE_SRC_DIR/Source/FreeImage/PluginTARGA.cpp:

In line 320 replace: @verbatim SwapShort(value); @endverbatim

with: @verbatim SwapShort(&value); @endverbatim

• 2.Enter the directory where the source files of FreeImage are located (FREEIMAGE_SRC_DIR).

@verbatim cd FREEIMAGE_SRC_DIR @endverbatim

• 3.Run the building process

@verbatim make
@endverbatim

• 4.Run the installation process
  • 4.1. If you have permissions to write to /usr/local/include and /usr/local/lib directories then run the following command: @verbatim make install
    @endverbatim
  • 4.2. If you don’t have permissions to write to /usr/include and /usr/lib directories then you need to modify the file FREEIMAGE_SRC_DIR/Makefile.osx:

Change line 49 from:   

@verbatim PREFIX ?= /usr/local @endverbatim

to:

@verbatim PREFIX ?= $(PREFIX) @endverbatim

  Change lines 65-69 from:

@verbatim 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) @endverbatim

to:

@verbatim 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) @endverbatim

Then run the installation process by the following command:

@verbatim make PREFIX=FREEIMAGE_INSTALL_DIR install @endverbatim

• 5.Clean the temporary files

@verbatim make clean @endverbatim
