Debugging from DAW Crash report

[A Former User]

If it was me I'd run Cubase the command line and it will output directly to the console in realtime.

Hmm interesting, can I open Cubase with command line in Windows?

@Steve-Mohican I don't know, try it and see.

@d-healey Ok thank you, I'll try...

Cubase crashes with my fx plugin. Is there anyway to debug from DAW crash reports?

@Steve-Mohican Yes, you can absolutely debug from a DAW crash report, but you need to be using a symbolicated version of your plugin when it crashes. To export a symbolicated plugin, you'll want your autogenerated Projucer file (found in the Binaries folder) to look like the screenshot below and then you must click the XCode button at the top and build from XCode with Product > Build For > Profiling.

When the crash report is symbolicated, you can look at the crashed thread and try to gauge what C++ function calls are executed before the plugin crashed.

So if the plugin crashes, where will the log file located?

@Steve-Mohican Crash logs can be found in the Mac Console app, which should list all the most recent crashes under "User Reports". It might be different depending on the computer, but I can always find mine here:

@Lunacy-Audio Thank you so much Casey, that helped a lot!! Wonderful! I am using Windows so I need to add those same flags to VS2017 Release version, right?

@Steve-Mohican I have yet to try on Windows! But I can imagine it's something similar. Maybe this forum post might provide some leads:

@Lunacy-Audio Thank you!

@Steve-Mohican It's just the debug build I mentioned earlier.

@Steve-Mohican It's just the debug build I mentioned earlier.

@d-healey I think it's slightly different, but correct me if I'm wrong. The Debug will be far less optimized than the symbolicated Release build, which may prevent you from testing it in a more realistic context. Sometimes crashes will only happen in Release builds and not the Debug because the Debug is so bloated and slow that the threading issues may not occur as they normally would. Just some food for thought. Probably a good idea to test in both.

@Lunacy-Audio You're probably correct, the debug build has no optimisation.
