This was fixed a while ago. Use VOLK version 1.2.3 or 1.3.

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.

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?
