Since you are using Slackware 13.1, you will have
either:
-to apply the patch that makes Qt3 libpng14-compatible (I
used the
attached one)
or
-to make the Qt3 build system use the Slackware-provided
libpng12
instead of the default libpng14 (the Trolltech-provided
libpng-1.2.5 is
full of security holes, and is deactivated by a patch of
mine that went
upstream…); a long time ago I tried this with Trolltech
3.3.8b and
Slackware 13.1 and didn't succeed.
I am using a libpng 1.4 patch to build qt3. Not the same as yours and I have updated to
use yours.
Are you building qt3 from the original tarball sources or from Trinity git?
