../src/unix/glx11.cpp(86): assert "xid" failed in SetCurrent(): window must be shown

[pwarren]

I'm running Debian 8 with liquidSDR and rtl-sdr built from source, others from system packages. It builds fine, but at runtime I get an error :(

I don't have my rtl-sdr dongle with me, so that might be an issue, but will test when I get home!

Backtrace follows below, as well as build info.

Interesting, it looks like it's initializing the GL context before it's ready? Are you using wxWidgets 3.0.2?

[cjcliffe]

Try the latest master, I've meged the linux branch fixes which included some issues with textures initializing before the canvas was visible.

[pwarren]

Yeah, the installed wx widgets are 3.0.2,

Using the latest master with #32 I do get a bit further, it creates an audio output thread and it displays better, without missing textures, but I still get the error, which comes up in a dialogue box.

[cjcliffe]

I'll try re-ordering the initialization and make sure everything is in view, I'll update this ticket with the branch information when ready

[cjcliffe]

Please check out the issue33-linux-setcurrent branch cjcliffe/CubicSDR@4dad30e9bd0043b2d28404b263f80d954f5f24e1 and let me know if that fixes your issue. There were definitely several instances where SetCurrent() was being called prior to the actual draw calls. Edit: Mind the branch issue number -- it is for this issue; just a typo.

[pwarren]

Yep, all fixed, thanks :)

I have a BladeRF, and I'll look at hacking in support for that over the next few weeks.
