gr-ieee802-11 grc files missing

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.

Hope it helps.

Thanks, Bastian. I tried this and got another error:

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.

like this:

strobe -> app_in
phy_out -> mac_in
mac_out -> phy_in
mac_out -> in (of parser)
