compile pixie 2.2.6 on Slackware 13.1 and set the enviroment variables as documentation
run rndr teapot.rib
rather boring teapot and a set of error messages in the form:
./teapot.rib (n): Error in shader "/opt/pixie/shaders/xxxxx.sdr" (0) ("syntax error") (v2.2.6)
./teapot.rib (n): Failed to find shader "xxxxx"
(where n is a line number and xxxxx is the shader name)
The text files in pixie/shaders are in DOS format with CR/LF line endings while the parser is expecting UNIX files with single \n
and the extra character does not parse
use the fromdos command (see man pages) to convert the shader files to unix format
much more interesting teapot and no error messages!
