Mayavi: Install python stuff from sourceΒΆ

Following http://www.enthought.com/enthought/wiki/GrabbingAndBuilding, you have to build/install VTK 5.0 and a few python extensions from sources.

All needed installation information for a given python module or VTK can be reached on its webpage.

For the impatient, these informations are resumed here.

Note about configure script: If you don't specify the destination where the packages will be installed, they will be installed by defaut in /usr/local.

We make the choice here to install them in a personnal directory, say ~/Mayavi2. So we set the environment variable DESTDIR to ~/Mayavi2, and will refer it later as DESTDIR:

Under sh shell-like, type:

In [ ]:
export DESTDIR=~/Mayavi2

Under csh shell-like, type:

In [ ]:
setenv DESTDIR ~/Mayavi2

Is is also supposed that you download and uncompress all tarball sources in a specific directory, named src/, for example.

Installing python2.3/python2.4¶

Download Python-2.3.5.tar.bz2 at http://www.python.org/download/releases/2.3.5 or Python-2.4.3.tar.bz2 at http://www.python.org/download/releases/2.4.3 and untar it in src/:

In [ ]:
cd src && tar xvfj Python-2.4.3.tar.bz2

Then run:

In [ ]:
cd Python-2.4.3/ && ./configure --enable-shared --enable-unicode=ucs4 --prefix=$DESTDIR

Then you can make & make install:

In [ ]:
make && make install

Installing VTK 5.0¶

Download vtk-5.0.0.tar.gz and vtkdata-5.0.0.tar.gz at http://public.kitware.com/VTK/get-software.php and untar them in src/:

In [ ]:
cd src/ && tar xvfz vtk-5.0.0.tar.gz && tar xvfz vtkdata-5.0.0.tar.gz

Note: cmake package must be installed before proceed.

Run:

In [ ]:
cd VTK && ccmake .

to create the required Makefile.

Press on "c" to configure.

Then press "enter" on the selected item to toggle flag.

You should specify some information, notably about some libraries location (tcl/tk libs + dev packages and python2.3/python2.4 you have just installed) if ccmake does not find them, and the destination (set it to DESTDIR).

Don't forget to set flag "VTK_WRAP_PYTHON" to on (and "VTK_WRAP_TCL" if you want to use Tcl/Tk):

In [ ]:
BUILD_EXAMPLES                   ON
BUILD_SHARED_LIBS                ON
CMAKE_BACKWARDS_COMPATIBILITY    2.0
CMAKE_BUILD_TYPE
CMAKE_INSTALL_PREFIX             DESTDIR
VTK_DATA_ROOT                    DESTDIR/VTKData
VTK_USE_PARALLEL                 OFF
VTK_USE_RENDERING                ON
VTK_WRAP_JAVA                    OFF
VTK_WRAP_PYTHON                  ON
VTK_WRAP_TCL                     ON

Press "c" to continue configuration:

In [ ]:
PYTHON_INCLUDE_PATH             *DESTDIR/include/python2.4
PYTHON_LIBRARY                  *DESTDIR/lib/libpython2.4.so
TCL_INCLUDE_PATH                */usr/include/tcl8.4
TCL_LIBRARY                     */usr/lib/libtcl8.4.so
TK_INCLUDE_PATH                 */usr/include/tcl8.4
TK_LIBRARY                      */usr/lib/libtk8.4.so
VTK_USE_RPATH                   *OFF
BUILD_EXAMPLES                   ON
BUILD_SHARED_LIBS                ON
CMAKE_BACKWARDS_COMPATIBILITY    2.0
CMAKE_BUILD_TYPE
CMAKE_INSTALL_PREFIX             DESTDIR
VTK_DATA_ROOT                    DESTDIR/VTKData
VTK_USE_PARALLEL                 OFF
VTK_USE_RENDERING                ON
VTK_WRAP_JAVA                    OFF
VTK_WRAP_PYTHON                  ON
VTK_WRAP_TCL                     ON

Note: you can press "t" to get more configuration options.

Press "c" and then "g" to exit configuration, then type:

In [ ]:
make && make install

Installing wx-Python2.6¶

Download wxPython-src-2.6.3.2.tar.gz at https://sourceforge.net/project/showfiles.php?group_id=10718 and untar it in src/:

In [ ]:
cd src/ && tar xvfz wxPython-src-2.6.3.2.tar.gz

Note: You should have GTK 2 installed i.e. you should have libgtk-2.6.* `and` libgtk2.6.*-dev packages installed.

Then run:

In [ ]:
cd wxPython-src-2.6.3.2/ && ./configure --enable-unicode --with-opengl --prefix=$DESTDIR

Then you can do:

In [ ]:
make; make -C contrib/src/animate; make -C contrib/src/gizmos; make -C contrib/src/stc

or follow instructions on wx-Python2.6 webpage, creating a little script which runs automatically the commands above.

Then install all:

In [ ]:
make install; make -C contrib/src/animate install ; make -C contrib/src/gizmos install; make -C contrib/src/stc install

To build python modules:

In [ ]:
cd wxPython

and run:

In [ ]:
./setup.py build_ext --inplace --debug UNICODE=1

and install them:

In [ ]:
./setup.py install UNICODE=1 --prefix=$DESTDIR

Installing scipy 0.5 & numpy 1.0¶

Download scipy-0.5.1.tar.gz at http://www.scipy.org/Download

Before installing scipy, you have to download and install:

* numpy-1.0.tar.gz (http://sourceforge.net/project/showfiles.php?group_id=1369&package_id=175103)

* Atlas libraries (you could install it with your packages manager, no need to build it in src/)

No special option are required to install these python extensions.

To install these packages in our \$DESTDIR, simply change directory and type:

In [ ]:
./setup.py install --prefix=$DESTDIR

That's all, folks !¶

Before installing !MayaVi2, you have to set some environment variables, to tell !MayaVi2 where python extensions can be found.

Under sh shell-like, type:

In [ ]:
export PYTHONPATH=$DESTDIR:$PYTHONPATH
export LD_LIBRARY_PATH=$DESTDIR:$LD_LIBRARY_PATH

Under csh shell-like, type:

In [ ]:
setenv PYTHONPATH ${DESTDIR}:${PYTHONPATH}
setenv LD_LIBRARY_PATH ${DESTDIR}:${LD_LIBRARY_PATH}
