I'm creating a GNU Radio OOT module in C++ language, in which I instantiate an osmosdr source. The syntax is : osmosdr::source ::sptr m_source = osmosdr::source::make();

I also implement other blocks in my design.

In CMakeLists.txt file, I specify all these components:

set(GR_REQUIRED_COMPONENTS RUNTIME BLOCKS FFT OSMOSDR)

find_package(Gnuradio-osdmosdr REQUIRED)

include_directories(

...

${GNURADIO_OSMOSDR_INCLUDE_DIRS}

)

link_directories(

...

${GNURADIO_OSMOSDR_LIBRARY_DIRS}  

)

In cmake/Modules folder, I copied the FindGnuradio-osmosdr.cmake file from gqrx project.

The logs of cmake command show that the osmosdr library is found:

-- checking for module 'gnuradio-osmosdr'

-- Found gnuradio-osmosdr, version v0.1.4-127-g4d83c606

-- Found GNURADIO_OSMOSDR: /usr/local/lib/libgnuradio-osmosdr.so 

After compiling the module (cmake .. -> make -> make install -> ldconfig), I got the error 'AttributeError: 'module' object has no attribute 'test'. I analysed the undefined symbol, and it was due to osmosdr module.

Any suggestion to solve this problem?

PS:

- I'm working on Ubuntu 16.04 (VM), gnuradio 3.7.9, cmake 3.5.1

- In GRC, the osmosdr source and sink work fine

Thanks.
