I actually don't know if it's the intended behavior that Gazebo requires to be run inside a VS shell. However, that's what was needed on my system. Without it (and with conda activated and workspace sourced), I get:

λ gz sim -s
Library error for [D:/programming/gz9-ws/gz-ws/install/bin/gz-sim9-gz.dll]: can't load D:/programming/gz9-ws/gz-ws/install/bin/gz-sim9-gz.dll

That is indeed strange. Are you using Command Prompt or Windows Powershell?

I'm using the command prompt.

Then something is indeed strange. If you want to debug more, you could try to load D:/programming/gz9-ws/gz-ws/install/bin/gz-sim9-gz.dll in https://github.com/lucasg/Dependencies in the same environment you are trying to run, and check if some dependent .dll is missing.

Weird. I just rebooted the computer and now it works in a normal CMD shell.

One possibility is that I'm using "conemu" as the command prompt, which normally just spawns a CMD subprocess and works the same as CMD. However, I've noticed that conemu is unable to reload system env variables if you change them - it always needs to reboot the computer. I don't know exactly which system variable it needed, but my guess is that this requirement to reboot can be attributed to conemu and that it should not affect other users.

I've removed the wording about VS command prompt from this PR.

We've noticed that versions of tinyxml or Bullet installed via chocolatey (as used in the ROS 2 install instructions) might cause weird issues like this.

Oh, I haven't dived into any ROS 2 + GZ tutorials. Combining Conda + Choco packages, that must be a very "interesting"... hell :-D
