#5 can't compile on Archlinux
Archlinux, like many linux distributions, provides kde4/qt4 by default. I have qt3 installed though, in /opt/
After changing the makefile to point INCPATH to /opt/qt/include, I got this:
g++ -c -pipe -march=i686 -mtune=generic -O2 -pipe -D_REENTRANT -Wall -W -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/share/qt/mkspecs/linux-g++ -I. -I/usr/include/QtCore -I/usr/include/QtGui -I/usr/include -I/opt/qt/include -I. -o agiplay.o agiplay.cpp
