@section dev_guides__building_3rdparty_linux_1 Introduction
This document presents additional guidelines for building third-party
products used by Open CASCADE Technology and samples on Linux platform.
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/Tk 8.5 - 8.6;
* FreeType 2.4.10 - 2.4.11;
* Optional products:
* TBB 3.x - 4.x;
* gl2ps 1.3.5 - 1.3.8;
* FreeImage 3.14.1 - 3.15.4.
@section dev_guides__building_3rdparty_linux_2 Building Mandatory Third-party Products
@subsection dev_guides__building_3rdparty_linux_2_1 Tcl/Tk
Tcl/Tk is required for DRAW test harness.
@subsubsection dev_guides__building_3rdparty_linux_2_1_2 Installation from sources: Tcl
Download the necessary archive from http://www.tcl.tk/software/tcltk/download.html and unpack it.
1. Enter the unix sub-directory of the directory where the Tcl source files are located (TCL_SRC_DIR).
cd TCL_SRC_DIR/unix
2. Run the *configure* command:
configure --enable-gcc --enable-shared --enable-threads --prefix=TCL_INSTALL_DIR
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:
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_linux_2_1_3 Installation from sources: Tk
Download the necessary archive from http://www.tcl.tk/software/tcltk/download.html and unpack it.
1. Enter the unix sub-directory of the directory where the Tk source files are located (TK_SRC_DIR)
cd TK_SRC_DIR/unix
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 --enable-64bit 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_linux_2_2 FreeType
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 (FREETYPE_SRC_DIR).
cd FREETYPE_SRC_DIR
2. Run the *configure* command:
configure --prefix=FREETYPE_INSTALL_DIR
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:
make
4. If the 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_linux_3 Building Optional Third-party Products
@subsection dev_guides__building_3rdparty_linux_3_1 TBB
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 and pick the archive for Linux platform.
To install, unpack the downloaded archive of TBB product.
@subsection dev_guides__building_3rdparty_linux_3_2 gl2ps
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 gl2ps are located:
ccmake GL2PS_SRC_DIR
* Press [c] to make the initial configuration;
* Define the necessary options in *CMAKE_INSTALL_PREFIX*
* Press [c] to make the final configuration
* Press [g] 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_linux_3_3 FreeImage
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*.
1. Modify *FREEIMAGE_SRC_DIR/Source/OpenEXR/Imath/ImathMatrix.h*:
In line 60 insert the following:
#include string.h
2. Enter the directory where the source files of FreeImage are located (FREEIMAGE_SRC_DIR).
cd FREEIMAGE_SRC_DIR
3. Run the building process
make
4. Run the installation process
a. If you have the permission to write into directories /usr/include and /usr/lib, run the following command:
make install
b. If you do not have this permission, you need to modify file *FREEIMAGE_SRC_DIR/Makefile.gnu*:
Change lines 7-9 from:
DESTDIR ?= /
INCDIR ?= $(DESTDIR)/usr/include
INSTALLDIR ?= $(DESTDIR)/usr/lib
to:
DESTDIR ?= $(DESTDIR)
INCDIR ?= $(DESTDIR)/include
INSTALLDIR ?= $(DESTDIR)/lib
Change lines 65-67 from:
install -m 644 -o root -g root $(HEADER) $(INCDIR)
install -m 644 -o root -g root $(STATICLIB) $(INSTALLDIR)
install -m 755 -o root -g root $(SHAREDLIB) $(INSTALLDIR)
to:
install -m 755 $(HEADER) $(INCDIR)
install -m 755 $(STATICLIB) $(INSTALLDIR)
install -m 755 $(SHAREDLIB) $(INSTALLDIR)
Change line 70 from:
ldconfig
to:
\#ldconfig
Then run the installation process by the following command:
make DESTDIR=FREEIMAGE_INSTALL_DIR install
5. Clean temporary files
make clean
@subsection dev_guides__building_3rdparty_linux_3_4 OpenCL ICD Loader
If you have OpenCL SDK (one provided by Apple, AMD, NVIDIA, Intel, or other
vendor) installed on your system, you should find OpenCL headers and
libraries required for building OCCT inside that SDK.
Alternatively, you can use OpenCL ICD (Installable Client Driver) Loader
provided by Khronos group. The following describes steps used to build OpenCL
ICD Loader version 1.2.11.0.
1. Download OpenCL ICD Loader sources archive and OpenCL header files from
Khronos OpenCL Registry
http://www.khronos.org/registry/cl/
2. Unpack the archive and put headers in *inc/CL* sub-folder
3. Print *make* in the root of the unpacked archive to compile OpenCL libraries.
4. Create installation folder for OpenCL IDL Loader package and put there:
1. OpenCL header files in *include/CL* subfolder
2. *libOpenCL.so* (generated in *bin* subfolder of source package) in *lib* subfolder
@section dev_guides__building_3rdparty_linux_4 Installation From Official Repositories
@subsection dev_guides__building_3rdparty_linux_4_1 Debian-based distributives
All 3rd-party products required for building of OCCT could be installed
from official repositories. You may install them from console using apt-get utility:
sudo apt-get install \
tcllib tklib tcl-dev tk-dev \
libfreetype-dev \
libxt-dev libxmu-dev \
libgl1-mesa-dev \
libfreeimage-dev \
libtbb-dev \
libgl2ps-dev
To launch binaries built with WOK you need to install C shell and 32-bit libraries on x86_64 distributives:
sudo apt-get install \
csh \
libstdc++5:i386 libxt6:i386
Building is possible with any C++ compliant compiler :
sudo apt-get install \
g++
