uic error compiling kde app

[Andy Goossens]

Hi all,

I just installed the first update for KDE-3.1.1 beta 1, but during the 
./configure process for a KDE application I get this error:

checking if UIC has KDE plugins available... no
configure: error: you need to install kdelibs first.


The following command completes succesfully:
/opt/kde3/bin/uic -L /opt/kde3/lib/kde3/plugins/designer -nounload -impl 
actest.h actest.ui > actest.cpp

But the resulting actest.cpp file doesn't have the "klineedit" include 
(everything else seems fine). That missing includes breaks the 
./configure process.
(See "if test -f actest.cpp && grep klineedit actest.cpp" line in 
admin/acinclude.m4.in)


After some investigation I might have found the cause. I removed ~/.qt 
and restarted the cygwin shell. This time, the uic command (see above) 
gave an error message:
Conflict in /opt/kde3/lib/kde3/plugins/designer/kdewidgets.dll:
   Plugin uses incompatible Qt library (3.1.2)!
at the position where the klineedit include should have been...

According to qtconfig and kde apps, they were using Qt 3.1.0 ...
