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.
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.
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
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.
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''.
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''.
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.
