I’m taking a look at the gr-ieee802-11 project. I’m unable to use
ofdm_loopback.grc because ofdm_phy_hier appears to be missing. I’ve
installed gr-ieee802-11 and gr-foo from Bastian’s github page. What step
am I missing?
Thanks,
Sean

I don’t know if there is a way to include hierarchical blocks in the
installation process. So for now you have to manually open
ofdm_phy_hier.grc and click build.
This installs the block in your ~/.grc_gnuradio folder. Then reopen grc.
Thanks, Bastian. I tried this and got another error:

Done

I have a patch applied that rename message ports. Maybe the connections
are therefore broken. Can you have a quick look if the gray ports are
connected. It should be easy to spot where the connections should be
(mac_out -> phy_in and so on).

They were not connected; I connected them and it compiled. There are
message block connections missing in ofdm_loopback.grc as well, but it’s
not as clear how they should be connected.
