I finally got it to compile (a tip to others who may be considering Konstruct: read the README, particularly the section on "Preconditions"...).
For the record, a newer version of autoconf did the trick.
However, now I have another problem: I can't get KDE to start. I get to the boot splash, which says "Setting up interprocess communication" for a while, then it disappears and I am left looking at a background.
I have these things in my .bashrc:
export QTDIR=/home/test/kde3.2-rc
export KDEDIRS=/home/test/kde3.2-rc
export WINDOWMANAGER=/home/test/kde3.2-rc/bin/startkde
export LD_LIBRARY_PATH=/home/test/kde3.2-rc/lib:$QTDIR/lib
export PATH=/home/test/kde3.2-rc/bin:$PATH
export KDEHOME=~/.kdetest
My .xsession-errors file can be found here:
http://hem.passagen.se/qazwsxq1/xsession-errors.txt
One of the things it says is that it looks like dcopserver is already running and that if I am sure it is not I should remove /home/test/.DCOP_server_localhost__0. I tried that, but that did not seem to help.
I would be very grateful if someone could tell me what is wrong.
