Some more ported apps

Mon Sep 24 07:54:00 GMT 2001

   		Hi everybody, 

I have  updated my web site with my latest ported apps on

        - gle-3.0.5 (static lib, erases the gle lib from glut)
        - glut-3.7 (static lib) 
        - xli-1.17.0
        - xloadimage.4.1
        - and finally xscreensaver-3.33

        Download them from
        Make sure to check the README files for requirements
        and usage.

	Comments are welcome....

BTW, I had problems with the JPEG files (in GQview, xli, xloadimage)
and tried some conversions with djpeg (I have the jpeg-6b-4 package).
It seems that there are problems with the DLL somewhere:
- lots of error messages when decoding JPEG files
- djpeg produces erroneous files
All files I used where tested on a Solaris and Linux djpeg/libjpeg
and produced no errors !

        ==> resulting ppm file is erroneous (garbage)

        Does anyone had or saw this problem ?
