Can anybody help please???

[jiapei100]

Yeah... A little extension to this issue:
where and how to speicify/define GZ_SIM_PHYSICS_ENGINE_PATH ???

Thank you ...

I think that we are looking for DART with the 6 major version because there hasn't been an official tagged release of the 7.0.0 versions yet. It should work with anything in the 6.x.x track, which is up to 6.13 these days (https://github.com/dartsim/dart/releases)

where and how to speicify/define GZ_SIM_PHYSICS_ENGINE_PATH ???

This is an environment variable. You can set it with

export GZ_SIM_PHYSICS_ENGINE_PATH=/path/you/want
