One possible problem is that the default Qt Plugin Path is wrong or
nonexistent. Best way to diagnose the issue would be to print out the
[A thought: to make our lives easier in the future, maybe I'll add a function
for this to qcatool (along with some other things perhaps, like listing the
actual QCA plugins found).]
Anyhow, the most likely offense is that Qt is not installed into the prefix
that it was configured for.
With Qt 3, the usual build process was to build it "in place" (ie, you unpack
it where you want it, configure and make. no 'make install'). With Qt 4,
this has changed, and now Qt follows a more typical procedure by allowing you
to specify a prefix and having a 'make install' function. The default prefix
is /usr/local/Trolltech or some such. The "in place" mode is still
available, if you set the prefix to the location of the Qt source. Do
'configure -prefix $PWD' and Qt will recognize it as an "in place" build.
In short, this means that if you build Qt 4 like you normally would build Qt
3, you're going to have a messed up installation. So maybe you want to check
that qt4 rpm.
