Build Error in CefRunMessageLoop Function

[Voltageist]

What, specifically, is the problem? Is your application terminating unexpectedly? Or is it just the crash on shutdown?

Your stack trace is from this error:

[0731/171621.311325:FATAL:context.cc(58)] Check failed: !g_context. CefShutdown was not called

Okay, let me try to set up some break points to get a stack trace at the correct error.

Because I'm actually getting an error a little before that CefShutdown error, during my call to CefRunMessageLoop:

Code: Select all

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  42 (X_SetInputFocus)
  Serial number of failed request:  267
  Current serial number in output stream:  269

Is there some visible behavioral symptom of this error which makes you think it's a problem?

So my code is basically a conversion of cefsimple's .cc files, but as .cpp files. When I run CEF's cefsimple binary I'm able to create a browser instance in a window that leads to google.com as a result. When I run my C++ version of this, a window spawns for a brief second but then seems to crash immediately. This window never actually leads to a browser instance or website, but is instead a white screen. I believe I'm very close to solving this, but something's failing right at the end.

It looks like you're not installing the X error handlers which keep the application from crashing on X error.

This seemed to resolve the issue (I also needed to add -lX11 to my gcc command). I also added the check for the CefExecuteProcess function. Thanks so much!
