I successfully built KDE 3.5.10 on Slackware 13.1, including many of extra apps. There were quite a few patches I had to find and apply. I'll submit any of those patches not yet merged into Trinity.

I also can build all of Trinity 3.5.12 on Slackware 12.2.

With that under me I started to build Trinity 3.5.12 on Slackware 13.1. I got qt3, qca, qca-tls, dbus-qt3 built and installed and poppler rebuilt to support qt3.

Then tqtinterface wouldn't build:

====================================

I seem to recall a while back of a similar breakage. I searched the list archives and there was mention of a similar error and somebody submitted some kind of patch.

Tim, do you remember which one? I would like to backport the patch.

I don't think this is related to the automake 2.64 issue because I have 2.65 installed. The 2.65 change log says that the AH_CHECK_HEADERS macro was reinstated.

Thanks.
