thanks
i am getting about linking comedilib.
i think the above error is sort out.now i am getting 
File "/home/jagdish/top_block.py", line 36, in <module>
    tb = top_block()
  File "/home/jagdish/top_block.py", line 28, in __init__
    self.comedi_source_s_0 = comedi.source_s( )
AttributeError: 'module' object has no attribute 'source_s'

is this error  due python path ?
i had installed 3 -4 block , i didn't get such kind of error.
i using ubuntu 10.10 , python2.6
all modules(gr, howto ,etc...) that i had installed are stored in
/usr/local/lib/(*.so , *.la *3.3.0.so.o , *.3.3.0.so.0.0.0) and in
/usr/local/lib/python2.6/dist-packages/
to compile comedi code i C compiler i used 
gcc filename.c -lcomedi -lm  and in GNURadio it compile it like normally gcc
filename.c.
is taht a problem ?

thanks
jagdish
