Hi Gesly,

I don't think I saw the post you're referencing.

In any event, gr-usrp does get compiled into a shared library.  That's
the mechanism we use to get our code loaded into python.

This fragment from gr-usrp/src/Makefile.am builds the shared lib.
The automake and libtool manuals will be helpful for decoding ;)


    ourlib_LTLIBRARIES = _usrp1.la


    _usrp1_la_SOURCES =                 \
            usrp1.cc                    \
            usrp1_sink_base.cc          \
            usrp1_sink_c.cc             \
            usrp1_sink_s.cc             \
            usrp1_source_base.cc        \
            usrp1_source_c.cc           \
            usrp1_source_s.cc           


    _usrp1_la_LIBADD =                  \
            $(PYTHON_LDFLAGS)           \
            -lstdc++


    _usrp1_la_LDFLAGS = $(NO_UNDEFINED) -module -avoid-version



Perhaps you can provide a bit more context?

Thanks,
Eric
