Installing the Vision Egg for SGI IRIX is similar to installing for linux. This document will covers mainly the differences from the linux installation process. I have installed the Vision Egg on IRIX64 6.5 using SGI's cc compiler.
Many of the tools used in the development of the Vision Egg are included on SGI's freeware distribution, so you might want to have that handy. (Despite SGI's choice, ''freeware'' is not the best term for open source software. ''Open source software'' has a couple more syllables, but is probably preferred by the authors of open source software, including the Vision Egg!) This method makes extensive use of SGI's Software Manager to install as much of the basic software as possible. Undoubtedly, because all of this software is open source, you could compile it yourself, as well.
Installing Python
Python compiles without trouble from the source, but I've had troubles getting the Tkinter module compiled. Therefore, I've been using precompiled Python from SGI's ''freeware'' distribution.
Installing Python Imaging Library (PIL)
I've had the following the error when building PIL:
The source file "tk.h" is unavailable. 1 catastrophic error detected in the compilation of "././_imagingtk.c".
I've just edited the file ''Setup'' and commented out the lines involving _imagingtk.
After building, my installation was:
cp PIL.pth /usr/freeware/lib/python2.1/site-packages/ mkdir /usr/freeware/lib/python2.1/site-packages/PIL cp *.so PIL/* /usr/freeware/lib/python2.1/site-packages/PIL
Installing PyOpenGL
I built from the PyOpenGL2 cvs repository checked out on 5 June 2002.
I changed the following lines in config/irix.cfg:
[General] build_togl=0 include_dirs=/usr/include:/usr/include/X11:/usr/freeware/include [GLUT] libs=Xi:Xmu
I had to regenerate (using swig1.3a5, which built just fine from source) the C interface files using ''python setup.py build_w''. From there, it was ''python setup.py build'' and then, as root ''python setup.py install''. After I wrote this document, I noticed that GLUT was not working, but I have not had a chance to go back and fix it. I believe the solution is simply to point PyOpenGL to libGLUT in the irix.cfg file and re-build.
Installing SDL
I installed from the ''freeware'' distribution. Make sure you install the subpackage ''SDL-1.2.3 full shared libraries'' from the package ''SDL-1.2.3 Simple DirectMedia Library''.
Installing pygame
Once I had SDL installed as above, installing pygame 1.5 was easy. The only quirk is to point pygame at SGI's default installation directory. Set your environment variable LOCALBASE to ''/usr/freeware''.
Installing the Vision Egg
This is a snap. Get the Vision Egg, decompress, move to that directory, and run ''python setup.py install''. You probably need to have root access.
Check your installation with the ''check-config.py'' program. Also run this script if you run into any installation errors.
