Are you sure you got that ipk file from kaffe.org?

What's a winmanager?

Dynamic linking of libawt fails. Read FAQ/FAQ.debugging and use gdb to figure
out what's really happening. Set a breakpoint on loadNativeLibrary and see if
you can find out what's the exact cause for the breakage.

There are so many ways for linking of c++ libraries to fail, it's not even
funny (bad moc version in path, bad QTDIr setting, bad QTEDIR setting, wrong
compiler ABI version, and whatever makes qt awt fail on my suse box right now
wtihout leaving a stack trave in the debugger while it works on my mandrake
box, or as the most bizarre cause I've seen with qt-embedded: not piping std*
streams to /dev/null ). Without going over through it using gdb, there is no
way you can find out what's the cause du jour ;)

I assume you should first ask wherever you got that ipk file from. I, for
example, don't even know what an ipk file is ;)

good luck hunting the problem down,
