I am new to meteor scatter detection but I am not new to software or electronics. Anyway, I decided to try and compile from svn trunk on Ubuntu 16.04 LTS from a direct svn checkout. I was hopeful knowing I already compiled GNU Radio that all the dev libs required would already be installed.
I used QT Creator to compile. The only issue I faced was in expfilt.cpp where isnan() was used. I had to add #include <cmath> and change it's usage to std::isnan() and then it compiled just fine at the second attempt.
Attaching my RTL to my high 2m vertical I got echoes working (a waterfall at least). I then used a HackRF and GNU Radio to create a fake echo at 1mW CW burst into a crappy antenna and bingo, got a hit on the waterfall so I know at least my setup seems to actually detect RF.
I now need to finish off mounting my 5 element yagi for the actual trials. In Scotland I am a bit far from the tx but it is worth a try.
For info, I have a 5 element 144MHz yagi to try and get GRAVES and a 6m Diamond beam antenna to try my luck at BRAMS.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I'll add your fix to 0.24 so in future you'll need no more to patch the
source.
good luck

Hi Giuseppe
I saw the patch on trunk, thanks :)
I will, in future, try and just supply any patches to save you having to do it. I will also look at getting a Ubuntu PPA package together.
regards,
