Regarding linking the libraries for undefined symbol error

[Arhum Ahmad]

Respected sir,

I am trying to transmit and receive packets in BPSK modulation for which I use GNU Radio Packetized transmissions<https://github.com/thomasverelst/gnuradioproject> named gr-packetizer. It was installed through source in ubuntu version 16.04. Even though it successfully installed, when it runs it gives an attribute error (like: AttributeError: 'module' object has no attribute 'packet_encoder'). In order to debug it was tested using "ctest -V" (image attach) command in the build directory which failed 50%. Also the command `ldd -r lib/*.so` in build directory gives undefined symbols, both of them point error in "volk_32fc_index_max_32u_manual". This I was unable to solve and understand. Please help me with this. All related images are attached. I'll be highly obliged.

all related versions are:

GNU radio - 3.7.9

cmake - 3.5.1

GNU make - 4.1

python - 2.7.12

python3 - 3.5.2

Thanks and Regards
