how to enable SoapySDR support #249

Closed sgoudelis closed 5 years ago

sgoudelis commented 5 years ago

Hello,

I just saw that SoapySDR support was added. I am trying to enable support by compiling pretty much everything I can find. SoapyRemote, SoapyRTL etc and the very recent sdrangel repos (commit bc7ad10f9d9a7694320e8ecebab65eb8b9c1b5e7). I setup soapysdrremote on two different boxes over the network.

I cant seem to find the options to configure inputs and outputs for SoapySDR on SDRangel. Can you guys point me to the right direction ?

If the installation is done right the various SoapySDR controlled devices should appear in the list of "sampling devices" that pops up when you press the change sampling device button: https://github.com/f4exb/sdrangel/blob/master/sdrgui/readme.md#32-open-sampling-device-change-dialog

This SoapySDR support is very new. I plan to write Wiki page(s) to describe how to compile and install the software right including SoapySDR which is a little bit special.

Yeap. It works. I recompiled everything and the devices show up. I 've got another issue. I see all devices twice. Please see attached image. menu_007

Any idea ?

First check how many "SoapySDR ..." plugins are listed when you open the "Help -> Loaded plugins" dialog. There should be only one pair of plugins: Input and Output.

Then the log shows where the plugins are looked for in the line that looks like: 2018-11-25 18:10:53.373 (D) PluginManager::loadPlugins: /opt/build/sdrangel/build.24/../lib/plugins , /opt/build/sdrangel/build.24/plugins

Then:

Indeed there are two pairs of plugins loaded. Thats the cause.

f4exb commented 5 years ago

This can happen if you try to start SDRangel from the build directory. Apparently in some cases the .so libraries for the plugins are produced in two different places under the plugin structure. It you start from the installation directory you will not have this problem.
