Re: SWIG doesn't recognize argument in make()

Hi Lukas - gr-petro is a OOT module - an "out of tree "module - it's not
part of gnuradio.

You need to contact the author of the module.

It's highly unlikely it's a problem with make - it's more likely a
mismatch between gr-petro and your installed version of gnuradio.

For instance, the OOT was written for a version of gnuradio prior to 3.8.

In any case, I couldn't find the gr-petro source code with a Google
search so I can't even guess what the problem might be. It also helps to
state which OS you're using.
