Re: [Discuss-gnuradio] Trying to build gr-fcdproplus for GR 3.8

[Volker Schroer]

Hi,

there was an error in the cmake script. As in the summary noted, the
bundled hidapi should be used.
Just fixed it in the git repositry. This should compile .
But I'd prefer, to use the latest hidapi.
You have to install something like libhidapi-dev and lib-hidapiusb0.

I'm not familiar with pip, But I think you installed the python bindings
of hidapi that are not used.

I hope, it works.
