I try to use the gmr1_rach_scan flowgraph, but did not succeed.

I am always getting this error:

Traceback (most recent call last): File "/home/peter/Radio/Thuraya/sylvain-gr/osmo-gmr/gr-gmr1/apps/gmr1_rach_scan.py", line 22, in <module> from gnuradio import gmr1 ImportError: cannot import name gmr1

The block is in the gr-gmr1 repo .. you build it with cmake like any other GR OOT.

Although I don't think I ever ported it to gnuradio 3.8 so it might need adaptation for that. Also it doesn't support mixed prefix install so you need to install it in the same prefix as your gnuradio.

Cheers,

Sylvain

I am using gnuradio 3.7, the build process stops with the following error, and i really don't know why, would be nice, if you, or anyone else can help me. Thank you!
