wxwidgets 3.1.7 dialog UI code integrated with eclipse crashing when using multiple threads with gtk3

[Sridhar@Work]

Hi

I'm using pthreads in RHEL8 (Linux) with wxwidgets dialog application and the dialog is integrated with eclipse plugin. When I use eclipse to perform some operations, I get the following warning and eclipse is crashing.

Code: Select all

Gtk-WARNING **: 16:22:27.696: gtk_disable_setlocale() must be called before gtk_init()
xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
java: xcb_io.c:261: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.

Do I have to initialize anything related XInitThreads for the code to work in Linux platform with Gtk3?
Please suggest.

Regards
Sridhar

Hi,
What is the backtrace at the time of the crash?
And most importantly - ARE YOU ACCESSING ANY GUI FROM A SECONDARY THREAD?
(Secondary here means "not the one that creates wxApp object)

Thank you.

No. There is no backtrace at the time of crash.

All the wxwidgets GUI is acessed from primary thread that creates the wxApp Object.

Any clues?

Does that mean you wrote en Eclipse plugin using wxWidgets and that's the one that crashes?
