[Discuss-gnuradio] New Block execution error

I develop a new block to my own library (called gr_my_divisorcamadas_ff) . The compilation runs successfully, but when I execute a flow graph with any block from the library, I got the following message:

Traceback (most recent call last):
  File "/home/rt-dsp/Desktop/Howtowrite/gr-my-basic/top_block.py", line 14, in <module>
    import gr_my
  File "/usr/local/lib/python2.7/dist-packages/gr_my/__init__.py", line 40, in <module>
    from gr_my_swig import *
  File "/usr/local/lib/python2.7/dist-packages/gr_my/gr_my_swig.py", line 24, in <module>
    _gr_my_swig = swig_import_helper()
  File "/usr/local/lib/python2.7/dist-packages/gr_my/gr_my_swig.py", line 20, in swig_import_helper
    _mod = imp.load_module('_gr_my_swig', fp, pathname, description)
ImportError: /usr/local/lib/libgnuradio-gr_my-3.3.0.so.0: undefined symbol: _ZTV23gr_my_divisorcamadas_ff

Even if I delete the reference from the new block in all make files and re-compile the library, the error still persist.

Any ideas?
