Re: How to enable local OOT modules

[Volker Schroer]

Hi Ivan.

I forgot to mention:

Have a look at ~/.gnuradio/config.conf

There is a sectioo

[grc]

This section should contain something like

global_blocks_path = /usr/local/gnuradio/share/gnuradio/grc/blocks
local_blocks_path = /usr/local/oot3/share/gnuradio/grc/blocks

Instead of setting GRC_BLOCKS_PATH

you can set local_blocks_path which should be evaluated in both cases.
