I think that is the case. However, this doesn't
cause
unexpected behavior and it
isn't a build error such as the direct access to the
png_info struct, etc.. I
don't know what is causing it, but we do need to clean it
up. All of the stray
'warnings' are telling us that something is not right. I'm
always suspicious
that 'warning1 + warning2 = unforeseen errors'.
What does this mean:
libpng warning: Interlace handling should be turned on when
using png_read_image
Is something not started or initialized before a call to
png_read_image? I'll
google around, if you already have the answer, let me
know...
I don't know. Have you tried "strace -o" and then search the strace output
file?
I have a basic idea how to create a libpng 1.5 patch as we did previously. If you find any
clues we can work together to cobble together a patch. But I can't test for libpng 1.5
because Slackware Current is at 1.4.9.
