hi
i am using RHEL(red hat).i have not mentioned any library path for qt libraries.But even then i dont get errors.i have checked for the environment variable and there is no Qt library path in the LD_LIBRARY_PATH variable.All i do the compile qt programs with qmake( /usr/local/Trolltech/Qt-4.4.2/bin/qmake) and run it.

How does Qt knows the library path.
