For the library, at least the correct glib version.
For using the headers, I guess the dev package (or how this is called on a normal distro)

The library should be installed in the common path for libraries (distro takes care of that).

i installed glib2-devel.., other libs.
now i am getting an compile error

cannot find -lSM

.

when i googled regarding issue, i came across a weird solution:

rename the lib to lib2(example) folder in qt and build the app.you wil get some complie issues.
again rename back to (lib) folder in qt .
build app .. surprise compile errors were gone and i can run my app..

Could any one explain me above issue?
I dont think this is the solution.
i have installed a qt bin package:qt-sdk-linux-x86-opensource-2009.04.1.bin

Could also please tell me wht libs required for my compile error.

Thnkz in advance.

Did you install libsm-dev (or something similary named like that)?
