Re: [sumo-user] libsumo GUI

[Mahima <mahima13@xxxxxxxxx>]

Thanks, Michael. It is now trying to open the GUI.

But I am getting the following error. I am running two parallel instances of sumo.

[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called

[xcb] Aborting, sorry about that.

qsumo: ../../src/xcb_io.c:165: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed.

Can you please suggest what else is missing at my end?

Thanks

Hi,
yes please set the environment variable LIBSUMO_GUI or use
Simulation::start with sumo-gui as first argument.
I added this to the docs.

Best regards,
Michael
