undefined symbol: _ZNK11btMultiBody12hasFixedBaseEv

[toontran]

Hello,

After installing all the required dependencies and modify the Makefile in DeepMimicCore/, I tried to run the python DeepMimic.py --arg_file args/run_humanoid3d_spinkick_args.txt in Ubuntu 18.04, which led to the issue undefined symbol: _ZN11btMultiBody22addJointTorqueMultiDofEiPKF (Issue #82).

After solving that issue with this solution, I got this new error: undefined symbol: _ZNK11btMultiBody12hasFixedBaseEv

I had the same issue. This helped for me: https://github.com/xbpeng/DeepMimic/issues/108#issuecomment-665538617

Turned out I had two different Bullet versions installed in two different folders.

Try the new build script added in master few days ago.

Well, the same problem. And I also have another undefined reference that is "_ZNK11btMultiBody15isBaseKinematicEv".

Thanks, but I think there's a little bit difference between the 2 problems. And I'm sorry that the solution doesn't work for me.

sorry for the bother.Have you fixed this problem?I met the same problem of this issue too. I have tried the solution provided by other issue, but still doesn't work.

maybe you need to delete all files generated using the last version? To run "make clean" or "rm * .o" might help

Thank you for your reply. I have fixed this problem by deleting all files generated using "make python", and running the new build script to automatically install all the package needed, it works finally.
