Qt Library on Ubuntu, strange style problem

[grayfox]

I compiled Qt 4.7.4 and Qt 4.8 on Ubuntu 11.04, the results are the same.
When I launch qtconfig/designer/assistant, the theme and font don't match the theme of Ubuntu, app linked with the frameworks also have strange style
6889
While using the QtCreator, QtCreator itself has style that matches the Ubuntu 11.04 style, but apps created from it don't, I tried using qtconfig to change among styles but nothing helps.
Also, if I launch qtconfig with sudo, the visual style becomes the Windows style...
Are there anyway to use the Ubuntu style in Qt-based app?

Did you build Qt with fontconfig support?

[grayfox]

here is how I run configure:


sh ./configure -opensource -debug-and-release -nomake examples -nomake demos -shared -fast -exceptions -no-accessibility -stl -no-qt3support -no-phonon -no-webkit -no-script -no-declarative -no-scripttools -no-declarative-debug -no-3dnow -no-openssl -qt-zlib -qt-libpng -qt-libtiff -qt-libjpeg -qt-sql-sqlite -qt-sql-mysql -I /usr/include/mysql -L /usr/lib/mysql

It's less relevant how you call configure, it is more relevant what it reports. At some point it should spit out the configuration it is going to use in a form of a list with yes/no info about each entry. Make sure fontconfig is there and the style your default Qt uses is there.

I just rerun configure, and the result is:

So, I don't have FontConfig support, and I also don't have GTK theme support.
How can I get it work? Thanks

In addition, I specified "-debug-and-release", but why would configure just ignore the debug build?
Configure output this as the configuration:

Start with: sudo apt-get install libfontconfig1-dev libglib2.0-dev libgtk-3-dev
Then rerun configure. It's likely you'll need to install more packages if you want additional features enabled (such as OpenGL, CUPS, OpenSSL, etc.).
