Re: [Discuss-gnuradio] gr-howto OOT tutorial crash

Hi,

I have been having some trouble with one of my OOT custom blocks in GRC (check this out: https://lists.gnu.org/archive/html/discuss-gnuradio/2017-07/msg00225.html) so I decided to try a bare bones version of the OOT module flow described here: https://wiki.gnuradio.org/index.php/OutOfTreeModules

All the steps are fine until 'make test'. The command crashes with a large traceback which isn't very helpful. This error is different from my original exercise of OOT modules, but nevertheless, I need to make sure at least the simple OOT module is Ok first on my system.

Here is the trace back error from 'make test'; any ideas how to proceed?

Thanks,
Vipin
