Re: [Discuss-gnuradio] Custom Blocks not being found

[Martin Braun]

The block tree is the data structure that holds the blocks and what GRC
uses to sort them on the right-hand panel. Is this an OOT? Then you
typically put them into the block tree by having a <category> tag in
your XML.
The other option is a block tree file, which is what the in-tree
components use. You can use the block tree files in OOTs, too.

Then make sure you run gnuradio-companion in a terminal. It'll print out
warning if it can't find stuff.
