Hi Hello! everyone.
in this fashion API changes these days, I found that debian and winbuntu old lasted revisions, has old libpng 1.2, especialy lenny with 1.2.22, which means that the patchs for libpng 1.4 support on qt3 for trinity can make impossible compile into Debian squeeze, testing inlcusive, as win-buntu 9.XX, it should be modified to use a macro -LIB_PNG_14 or something similar .. I do not remember how to work with this but if I can do for the weekend..
If some body can do that , please change the patch for use optionaly both library versions...
If i can resolve all issues, i do a qt3 3.3.c tar gzipped release alternate for ready download in public, for easy acces to novice developers
I have libpng 1.4.5-1 installed and this patch for qt3 works for me
