The machine is on an Ubuntu 20.04

I also try to follow GitHub issues on mjpc repo, but I am still not able to install the python interface.

[qianqianlo]

Same problem. @leo-liuzy have you solved this issue?

[fxia22]

It seems the error message is buried one level deeper, can you show the full error log?

[qianqianlo]

@fxia22 the full log contains the build process and it's quite long. I put it in a shared google doc: link

[yichaoshen-MS]

It seems the error message is buried one level deeper, can you show the full error log?

I find the same error.

[fxia22]

Seems the root cause is

but it seems a bit weird, since it should be fixed it here https://github.com/google-deepmind/mujoco_mpc/commit/74763c51624d9e9a61027e5eeb68d0affc097992

[fxia22]

could you try upgrading mujoco_mpc to the latest version?

[doldam0]

Could you try removing build directory?

[SebastienJin]

I have the same problem and it's solved by updating the version of clang.

[saloneeverma]

Has anyone else solved this issue just by updating the version of clang? It didn't work for me; none of the other suggestions worked either.

[nimrod-gileadi]

Could you confirm that you are following the installation instructions in the README exactly (including checking out the particular commit of mujoco_mpc, where we tested the build)?
