zs,

Have you gone through our tutorials?

http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorials

That walks through the process of creating your own module and blocks. It might point out something that you did incorrectly when building your own. There is also the tutorial on building out-of-tree modules that might also be of use:
