I've been debugging what happens when using nxview. Here's some output:
nxview /usr/logo.gif
HandleClient GrOpen
Going to call GrLoadImageFromFile
Calling AllocReqExtra
going to memcpy
calling GrTypedReadBlock
entering GrReadBlock
HandleClient GrLoadImageFromFile
GrLoadImageFromFileWrapper entered
calling GdLoadImageFromFile
GdLoadImageFromFile: opened file /usr/logo.gif OK
malloced OK
LoadGIF called
The nxview program calls GrLoadImageFromFile, which ends up in the server
and it calling LoadGIF.
It seems it never returns from there - at least the call to
GrLoadImageFromFile does not return, as I have put some debug messages after
that call.
I'll have to debug further tomorrow to see what's going on in LoadGif and
locate where it dies.
Interesting anyway to discover a little bit about the structure of nano-x
;-)
