Screaming about QT Copy weirdness ;-)

[Andras Mantia]

Hi,
 
 Here an e-mail sent to the kde-devel list from one who has run into this 
problem. And he is not the only one, for some it seems to be impossible to 
compile kdelibs with a recent qt copy. Until now no solution was found / or 
posted. Even if it is not a kde error, I think the solution for this MUST go 
into a compilation FAQ and posted to the kde-devel list, as many will have 
such errors also in the future. I admit that I have no idea why do some get 
the error and others not. I'm one of the lucky guys who don't have 
problems...
 So I "scream" instead of others, just a Dirk requested. ;-)

I'm using gcc 2.95.4, automake 1.5, autoconf 2.53, debian 3.0.

qt-copy compiles fine (with  ./configure -system-zlib -qt-gif -system-libpng
-system-libjpeg   -plugin-imgfmt-mng -thread -no-stl -no-exceptions -debug
-fast -prefix /opt/qt3)

arts is also fine but then kdelibs bombs out with:

It's been like this since the move to Qt 3.1, the recent qt-copy update
 didn't change anything. I've also removed qt-copy and kde* and re-checked
 out, to no avail.

Anyone got any ideas?

Cheers, Simon
