Yes, I just double-checked and mine is working. So, I just re-checked your link to issue #406. In "steps to reproduce", I noticed 2 things:
- On the next-to-last line, the g++ command does not include your custom library and does not include this link option. The Ettus example builds your block controller in its own shared library - it does not add it to the uhd shared library. So, you need to link with both uhd and your rfnoc-example shared library (or whatever it is named). And, you need to have that link option. (as a side note, when you built the rfnoc-example, this did build the init_gain_block.cpp example in the apps folder with this link option so if you were to run that example, you could confirm that the block ID in that example is "Gain#0" rather than "Block#0". But since this example doesn't use the radio, you couldn't use it to verify action propagation). - The final step in "steps to reproduce" shows a command line with the block ID "Block#0". If the block controller library was linked properly, this will not be the Block ID. It will be "Gain#0" or something like that.
