Re: [Discuss-gnuradio] gr-lte updated to GNU Radio 3.7 API

[Mike Cornelius]

Hi Ralph,

I had the same problem at first myself, there is no need to reconnect anything in the top_level.grc block so long as all the hier blocks have actually been compiled.

In my case the biggest problem was the LTE_estimator_hier block would not compile because the 'import lte' failed (see earlier messages in this thread for details).

Hi everybody,

I added screenshots for all the hierarchical flowgraphs and the top
flowgraph to the docs directory. I hope this helps to build the whole
LTE flowgraph in GRC.
Although, I realized that would be very helpful if the hierarchical
flowgraphs would be compiled with grcc during make and then installed.
Preferably added to a CMakeLists file. I will look into this.

Happy hacking
Johannes
