Hi Berndt

I seem to have the information found in the libjpeg.a file as you do, in a 
different place, but I assume that this should be ok ?

[ian at localhost BSPLoader_OGL]$ nm /usr/lib/libjpeg.a | grep jpeg_read_header
000001c0 T jpeg_read_header

I have also re-installed all of the libjpeg from the mandrake v9.0 disks so 
hopefully I should have all of the information required ?
I have installed
libjpeg62-devel
libjpeg62-static-devel
libjpeg-progs
libjpeg62

Is there any other packages that I require ?  

Cheers
Ian
