Building TiGL from Source

Windows

We recommend building TiGL with Visual C++ 2015 as a 64bit variant. The free Visual C++ Express also works. Other compilers should do as well, but we don't porivide any support for them.

Getting the prerequisites

• Download the CMake installer from http://www.cmake.org/ and install it.
• Download and extract our precompiled OCE MSVC2015 binaries from sourceforge: https://sourceforge.net/projects/tigl/files/Thirdparty/oce.0.17.2.win64_msvc2015_static.7z/download. Alternatively, build oce by yourself and apply the patches from our patches directory.
• Download and extract latest TiXI binaries from https://github.com/DLR-SC/tixi/releases
• Optional: Download and install Qt for VS2010 from http://download.qt.io.

Build steps:

1. Extract the TiGL Code to a directory of your choice. In this tutorial, the directory will be d:\src\tigl
2. Open the command shell (Press Windows key and type in cmd.exe)
3. Change into the TiGL source directory, e.g.

cd d:\src\tigl

4. Create a build directory and change into it

mkdir build && cd build

5. Create the building environment by running cmake

cmake -G "Visual Studio 14 2015 Win64" -DTIXI_PATH=d:\src\tixi-binaries -DCASROOT=d:\src\oce-binaries -DCMAKE_INSTALL_PREFIX=install ..

You might change the paths where you extracted TiXI and OCE.

6. If everything is fine, close the command shell. Open the Windows Explorer and go to the d:\src\tigl\build directory. Open the TIGL.sln file with Visual C++.

7. In Visual C++, perform the Release build of the ALL_BUILD project. The Debug build would require a special OCE debug version.

8. Finally install TiGL by building the INSTALL project. You can find the installed TiGL in d:\src\tigl\build\install

Ubuntu / Mint / Debian Linux

Getting the prerequisites

1. Please add our package repository matching your distribution via

echo 'deb http://download.opensuse.org/repositories/science:/dlr/xUbuntu_16.04/ /' >> /etc/apt/sources.list.d/tigl.list 
sudo apt-get update

Replace the string xUbuntu_16.04 by your distribution id. This allows installing opencascade and tixi from out repository.

2. Install the dependencies via

sudo apt-get install cmake libtixi-dev qt4-dev-tools liboce-dev

Build steps:

1. Download and extract the tigl source. For this tutorial, TiGL is extracted to $HOME/src/tigl
2. Open a command shell, enter into the TiGL directory and create a build directory by:

cd $HOME/src/tigl
mkdir build

3. Create the makefiles by running cmake:

cmake -DCMAKE_INSTALL_PREFIX=install ..

You might change the installation directory.

4. If no errors occured, build TiGL:

make

5. (Optional) install TiGL:

(sudo) make install

sudo is only required, if you want to install it into a system path like /usr/local

Mac OS X

Getting the prerequisites

• Download the CMake installer from http://www.cmake.org/ and install it.
• Download the OCE source and build it as described in the OCE wiki
• Build TiXI from source (see https://github.com/DLR-SC/tixi/wiki/InstallationHowto)
• (Optional) Download and install QT 4.8. (http://download.qt.io/archive/qt/4.8/)

To build TiGL, follow the same build steps for linux. In the cmake configuration, you have to add the OCE installation directory and the TiXI installataion directory:

cmake -DTIXI_PATH=$HOME/src/tixi/build/install -DCASROOT=$HOME/src/oce/build/install -DCMAKE_INSTALL_PREFIX=install ..

Python interface

If python is installed, the python interface will be automatically built at the compile phase. The resulting file tiglwrapper.py is located under buildDir/lib/. When using the TiGL installer, the python wrapper can be found in installDir/share/tigl/python/. To install the TiGL python wrapper, please copy this file in your python/Lib/site-packages/ folder.
