compile the Qt Package from Nokia ( former Trolltech ).
I used the Sun Studio Compilers, but ran into a compile problem, where I had
to set an additional compile/link flag see here for the message.
The configure option I used was:
CC=/opt/sunstudio12.1/bin/cc CXX=/opt/sunstudio12.1/bin/CC CXXFLAGS="-library=stlport4" LDFLAGS="-library=stlport4" ./configure --prefix=/tools/qt/4.5.3 -opensource
After this, just a gmake and gmake install and everything was fine.
