M17 tx/rx channel not available on 20.04 #1349

Closed alphafox02 closed 2 years ago

I've tried both the deb file, doesn't seem to show any mention of M17 plugin loading and then built from source the latest SDRAngel which shows this during loading.

2022-07-18 15:24:46.933 (W) PluginManager::loadPluginsDir: Cannot load library /opt/install/sdrangel/lib/sdrangel/plugins/libmodm17.so: (/opt/install/sdrangel/lib/sdrangel/libmodems.so: undefined symbol: _ZN8modemm1713ClockRecoveryILm48000ELm4800EE9MIN_CLOCKE)

I'll continue to look into this.

Looking over the ClockRecovery.h didn’t help, but it lead me here - which didn’t really help either https://github.com/mobilinkd/m17-cxx-demod

Possibly related to this https://github.com/f4exb/sdrangel/issues/1343 ? I get a different outcome (as described in that thread) but it involves M17, and I see Edouard made some recent commits with some references to M17...

alphafox02 commented 2 years ago

I see we get different results. I went and posted over in the other ticket you mentioned, although I don’t have much info to provide since the compile completed and I didn’t seem to have errors during the process. I’ll try again today.

alphafox02 commented 2 years ago

Taking a look the official 20.04 deb packages that were created after the M17 plugin reveals there's no M17 lib in sdrangel and/or plugins.

f4exb commented 2 years ago

You don't have the FreeDV mod and demod either probably because codec2 is not properly detected. I will not fix this.

alphafox02 commented 2 years ago

Edit: I see what’s going on now after reading other tickets.

alphafox02 commented 2 years ago

Oh I think I see what you mean. This is added to a later milestone?

f4exb commented 2 years ago

Well... no. I means I will not do anything about this.

alphafox02 commented 2 years ago

Circling back around to this after hearing from at least one other person that compiling SDRAngel from source does not present the m17 plugin.

Can you please clarify weather or not the plug-in is building and usable on some Linux distros? Your responses are rather short and I can’t tell if you’re only speaking to the deb package not having the plug-in or if your saying that even building from source will not allow it to work right now.

@srcejon maybe you can expand on this too so I don’t keep chasing something if it’s not possible right now. I thought about going to a 22.04 machine and seeing if I get the same issue.

Freedv modulator and demod is actually present.

I just created a different ticket since there seemed to be some confusion on this one. Hopefully the second is cleaner and offers a better understanding of the problem.
