Ubuntu Flavors

Version shipped in repositories is 0.6.0 (as of 7th July 2011) so if we want 0.7.x we need to build it from source.

Ubuntu 11.04

• Install dependency packages:

  sudo apt-get install build-essential pkg-config python-dev libfreetype6-dev libpcre3-dev libboost-python-dev libglut3-dev libpng-dev libmng-dev libjpeg-dev libfreeimage-dev

• Obtain a copy of CEGUI here
• Extract to a folder
• Before we build, we have to symlink the site-packages directory correctly, so it installs to the correct place.

First, we move the contents of site-packages to dist-packages.

sudo mv /usr/local/lib/python2.6/site-packages/* /usr/local/lib/python2.6/dist-packages/

Now, we remove site-packages, and symlink it to dist-packages

sudo rmdir /usr/local/lib/python2.6/site-packages
sudo ln -s /usr/local/lib/python2.6/dist-packages/ /usr/local/lib/python2.6/site-packages

• Build CEGUI with python support

./configure && make && sudo make install && sudo ldconfig

• Note: On some Ubuntu systems it seems that CEGUI's configure system does not correctly detect the Python headers. To solve this, do the following:

export CXXFLAGS=-I/usr/include/python2.7
./configure && make && sudo make install && sudo ldconfig

Ubuntu 11.10

• Install dependency packages:

  sudo apt-get install build-essential pkg-config python-dev libfreetype6-dev libpcre3-dev libboost-python-dev libpng-dev libmng-dev libjpeg-dev libfreeimage-dev libtool autoconf

• Patch CEGUI:

There are two patched required to make CEGUI 0.7.5 compile correctly with python support, on 11.10. They are:

ptrdiff_t.patch

Copy the contents of the code blocks above, and paste them into files of the correct name (ptrdiff_t.patch and python27.patch respectively). Then apply the patched like so:

$ patch -p0 < ptrdiff_t.patch
$ patch -p0 < python27.patch

• Regenerate configure:

$ ./bootstrap

• Build CEGUI with python support

./configure --disable-external-tinyxml && make && sudo make install && sudo ldconfig

Note: The tinyXML shipping with Ubuntu 11.10 is too new, and doesn't compile, hence we disable it.

Still not working?

You can try running your program with:

PYTHONPATH="/usr/local/lib/python2.6/site-packages:$PYTHONPATH" python <file.py>

Note for Panda3D users You can run your program at the same way, using:

PYTHONPATH="/usr/local/lib/python2.6/site-packages:$PYTHONPATH" ppython <file.py>
