[Discuss-gnuradio] Error building gr-burst in Ubuntu 16.04 and Volk 1.2.1

[katutxakurra]

Hi,

I'm trying to compile gr-burst and I'm getting an error. I've opened an issue in Github but I'm hoping to get a wider audience here.

https://github.com/gr-vt/gr-burst

I'm using Ubuntu 16.04 with GNURadio 3.7.9, Volk 1.2.1, SWIG 3.0.8 and libgsl2 2.1.
I have installed python-bitarray and build/install gr-mapper.

In gr-burst, I made
cmake CMakeLists.txt

There are some warnings about policies and not finding gsl-config.

It looks like the error is with Volk and similar to the one described here
git-artes/gr-isdbt#18

Does anyone know how could I fix or work around this problem?
