Re: [Discuss-gnuradio] libserial c++ with gnuradio

[Marcus Müller]

Hi Ayman,

you wrote your original question on a sunday and try to hurry things by asking but 24hrs later -- that might be a bit impatient for an open source project with volunteers trying to help you with something that has not much to do with their project, but with your usage of a completely different library ;)

However: you're not linking properly against your serial library, as it seems. Make sure you modify the CMakeLists in your project's root and lib/ folder to include the library you want to link against..

Best regards,
Marcus

Hi,

I installed libserial to access serial port by C++ from gnu radio, I
included
#include <SerialStream.h>
#include <iostream>
to lib/XXXX.cc file,
I can compile successfully, but when I run top_block.py file I get the
following error,

Traceback (most recent call last):
  File "./top_block.py", line 13, in <module>

ImportError: /usr/local/lib/libgnuradio-C700.so: undefined symbol:

what is this? kindly advice.

Thanks
