As I searched and debugged, I've found the fix, but not the reason:
there is a config file in /etc/gtk-2.0 named "gdk-pixbuf.loaders", and this file
contains the "header" and "magic" data to "recognize" a image file type. When
compiling, this file is obviously not used, but a "sample" of it is used during
compilation.
So the fix is, if I change this file before this "test" reaches during the
compilation, the compilation goes on, and all work fine, but what I've did, I'm not
proud of it :+)
I changed the "magic/header" data between png and tga:
from:
"/usr/lib/gtk-2.0/2.2.0/loaders/libpixbufloader-png.so"
"png" 1 "gtk20" "The PNG image format"
"image/png" ""
"png" ""
"\211PNG\r\n\032\n" "" 100
to:
"/usr/lib/gtk-2.0/2.2.0/loaders/libpixbufloader-png.so"
"tga" 0 "gtk20" "The Targa image format"
"image/x-tga" ""
"tga" "targa" ""
" \001\001" "x " 100
" \001\t" "x " 100
" \002" "xz " 99
" \003" "xz " 100
" \n" "xz " 100
" \013" "xz " 100
After doing that in both the /etc config file, and the sample during the compilation,
the build goes on, and work, but as you can see, the png format is recognized as a TGA
header, and if you look into a .png file and a .tga image, you will see the BIG
difference between headers.
I also had this same problem in debian, but I didn't discovered it, just an upgrade (I
was using unstable) fixed it.
Somebody else with the same error and a good "reason" for that????
