Building with Automake
This file describes steps to build OCCT libraries from complete source archive on Linux with GNU build system (Autotools).
If you are building OCCT from bare sources (as in Git repository), or do some changes affecting CDL files, you need to use WOK to re-generate header files and build scripts / projects. See \ref dev_guides__building__wok for instructions.
Before building OCCT, you need to install required third-party libraries; see OCCT_Build3rdParty_Linux.pdf for instructions.
Note that during compilation by makefiles on some Linux OS on a station with NVIDIA video card you may experience problems because the installation procedure of NVIDIA video driver removes library libGL.so included in package libMesaGL from directory /usr/X11R6/lib and places this library libGL.so in directory /usr/lib. However, libtool expects to find the library in directory /usr/X11R6/lib, which causes compilation crash (See /usr/X11R6/lib/libGLU.la).
To prevent this, suggest making links:
ln -s /usr/lib/libGL.so /usr/X11R6/lib/libGL.so ln -s /usr/lib/libGL.la /usr/X11R6/lib/libGL.la
1.In OCCT root folder, launch build_configure script
This will generate files configure and Makefile.in for your system.
2.Go to the directory where OCCT will be built, and run configure to generate makefiles.
$CASROOT/configure <FLAGS>
Where <FLAGS> is a set of options. The following flags are mandatory:
- --with-tcl= defines location of tclConfig.sh
- --with-tk= defines location of tkConfig.sh
- --with-freetype= defines location of installed FreeType product
- --prefix= defines location for the installation of OCCT binaries
Additional flags:
- --with-gl2ps= defines location of installed gl2ps product
- --with-freeimage= defines location of installed FreeImage product
- --with-tbb-include= defines location of tbb.h
- --with-tbb-library= defines location of libtbb.so
- --enable-debug= yes: includes debug information, no: does not include debug information
- --enable-production= yes: switches code optimization, no: switches off code optimization
- --disable-draw - allows OCCT building without Draw.
If location of FreeImage, TBB, and Gl2Ps is not specified, OCCT will be built without these optional libraries.
Attention: 64-bit platforms are detected automatically.
Example:
./configure -prefix=/PRODUCTS/occt-6.5.5 --with-tcl=/PRODUCTS/tcltk-8.5.8/lib --with-tk=/PRODUCTS/tcltk-8.5.8/lib --with-freetype=/PRODUCTS/freetype-2.4.10 --with-gl2ps=/PRODUCTS/gl2ps-1.3.5 --with-freeimage=/PRODUCTS/freeimage-3.14.1 --with-tbb-include=/PRODUCTS/tbb30_018oss/include --with-tbb-library=/PRODUCTS/tbb30_018oss/lib/ia32/cc4.1.0_libc2.4_kernel2.6.16.21
3.If configure exits successfully, you can build OCCT with make command.
make -j8 install
To start DRAW, launch
draw.sh
