Hi,
I just updated my web site with my latest ported apps on
Cygwin/XFree:
- 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 http://lassauge.free.fr/cygwin/
Make sure to check the README files for requirements
and usage.
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 djpeg/libjpeg and produced
no errors !

Does anyone had or saw this problem ?
