[Interest] 'Gtk theme support cannot be enabled due to functionality tests' Error

[Jeff Huber]

New to QT and C++ ........

Compiled a new 64 bit 4.8 with Oracle and other DB support. That part 
worked great. But when I select the new build in Creator and compiled my 
application the app is really ugly – no GTK theme. The build that came 
with the SDK (Creator ) works just fine. So its my build that has the 
problem.

So I ran configure with -gtkstyle -v to try and get themes working. No 
luck and no useful output from configure:
……
XInput auto-detection… ()
g++ -c -m64 -pipe -O2 -Wall -W -I../../../mkspecs/linux-g++-64 -I. 
-I/usr/include -o xinput.o xinput.cpp
g++ -m64 -Wl,-O1 -o xinput xinput.o -L/usr/X11R6/lib64 -lXi -lXext -lX11 -lm
XInput enabled.
XKB auto-detection… ()
g++ -c -m64 -pipe -O2 -Wall -W -I../../../mkspecs/linux-g++-64 -I. 
-I/usr/include -o xkb.o xkb.cpp
g++ -m64 -Wl,-O1 -o xkb xkb.o -L/usr/X11R6/lib64 -lXext -lX11 -lm
XKB enabled.
Gtk theme support cannot be enabled due to functionality tests!

All it says is “Gtk theme support cannot be enabled due to functionality 
tests!”.

Can someone point me toward the missing requirements ? Nothing comes 
back in Google.

I compiling on 64 bit Ubuntu Gnome 11.04.

Thanks
