"Failed to start capture due to errors:"

[miek]

When I start a capture, I get a popup with just the text "Failed to start capture due to errors:". I've tried with both a HackRF source and a file source (complex f32 samples) and get the same result.

I'm running Ubuntu 18.04 and I am running a slightly older Qt version than suggested (5.9.5) but I think it's unrelated?

I'm happy to dig in and do some more debugging but I don't really know where to start, so I'd need some advice on things to try.

Hi miek,

Is there any additional information in that popup message? Also, a file named ~/.suscan/config/uiconfig.xml should have been created in your system, containing SigDigger's config (including the signal source config). Could you attach this file here?

Thank you,

[miek]

There's no other information in the popup.

I've attached uiconfig.xml for each configuration (renamed 'cause github is scared of xml files apparently...).

uiconfig-filesource.txt
uiconfig-hackrf.txt

Thanks

I've just installed Ubuntu 18.04 and reproduced this behavior, I'm already looking into it.

Edit: whatever the problem is, it is not in suscan. It has to bee somewhere in Application.cpp, method startCapture.

Well, it ended up being in suscan 😄

File analyzer/analyzer.c, function 1232:

SUBOOL
suscan_analyzer_set_iq_reverse(suscan_analyzer_t *analyzer, SUBOOL rev)
{
  analyzer->iq_rev = rev;
}

Must be modified to:

SUBOOL
suscan_analyzer_set_iq_reverse(suscan_analyzer_t *analyzer, SUBOOL rev)
{
  analyzer->iq_rev = rev;
  return SU_TRUE;
}

I'm adding a hotfix right now, could you try to change this file and verify whether it works?

[miek]

Yep, that works. Thanks very much for solving that!
