Hello,

I’m currently trying to port ‘gr-csitool’ (https://github.com/qiank10/gr-csitool) from gnuradio v3.7 to v3.8 in OS X.

I’ve installed gnuradio via MacPorts.

While I’ve followed instruction from 'https://wiki.gnuradio.org/index.php/GNU_Radio_3.8_OOT_Module_Porting_Guide’,

I got a problem while linking (I think).

Since gr-csitool requires ‘itpp’ library, I’ve installed and trying to include it to OOT modules, but it seems not working.

In lib/CMakeLists.txt, I added 'target_link_libraries(gnuradio-csitool gnuradio::gnuradio-runtime gnuradio::gnuradio-blocks gnuradio::gnuradio-fft gnuradio::gnuradio-filter Volk::volk itpp)’

Then, while making, it shows linker failure as below:

Here is my cmake command (if neededd)

CC=/usr/bin/llvm-gcc CXX=/usr/bin/llvm-g++ cmake \

-DPYTHON_EXECUTABLE=/opt/local/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7 \

-DCMAKE_INSTALL_PREFIX=/opt/local ..

Can I have any hint?

Thanks a lot!
