Version mismatch detected:carla is incompatible with this API

[changer707]

When I run CARLA AD demo,I got this problem as following: WARNING: Version mismatch detected: You are trying to connect to a simulator that might be incompatible with this API WARNING: Client API version = 4dc4cb81 WARNING: Simulator API version = 94cb1595

No vehicle is spawned in simulator.

Hi @changer707! As the WARNING says, you are using different versions of the CARLA client and the CARLA server. Sometimes this is not a problem and everything works as expected. Please, make sure you use the same version. Are you getting any other error when running the CARLA AD demo?

I am getting the same version mismatch problem, even though I think I'm doing the correct thing. I am running Carla 0.9.10.1 binaries on my Windows machine, and I checked out ros-bridge with tag 0.9.10.1 and built this from source on Ubuntu 20.04 in WSL. But when I run ros-bridge, I get the version warning and it fails to communicate with Carla:

[WARN] [1609390685.556875, 0.000000]: Version mismatch detected: You are trying to connect to a simulator that might be incompatible with this API. Client API version: 784d9b9f. Simulator API version: 0.9.10.1
WARNING: Version mismatch detected: You are trying to connect to a simulator that might be incompatible with this API
WARNING: Client API version     = 784d9b9f
WARNING: Simulator API version  = 0.9.10.1

How can I build a ros-bridge client that is compatible with the simulator version 0.9.10.1? I thought simply checking out the right tag would do it, but apparently not.
