gr-dpd's Issues

problems with LIBVXI11

Hi,
when running the cmake for the gr-dpd I get this error:
-- Checking for module 'libvxi11'
-- No package 'libvxi11' found
-- libvxi11 not found.

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
LIBVXI11_INCLUDE_DIRS (ADVANCED)

but the LIBVXI11 is installed correctly like says in the LIBVXI11 repository within the dpd-externals folder with next command:
./configure --prefix=/home/julian/gnuradio/gr-dpd/dpd_externals/libvxi11

It's possible to compile the library without the libvx11? since I don't need this library for the spectrum analyzer.

AttributeError: 'module' object has no attribute 'attribute'

Hi,
running some of the examples located in apps folder I get errors with the Attributes passed to the modules.
I don't know if this is an error related with my gnuradio enviroment or with gr-dpd. due in the net there is similar error with different solutons but none of them work for me.
Thanks,
regards.

Hi,
I am facing below error in building gr-dpd when I run the command "cmake .."
