Boost.Python.ArgumentError: Python argument types did not match C++ signature

[henrykmichalewski]

Can you help with the following boost-related error?

$ python python/gps/gps_main.py mjc_example
DEBUG:No ROS enabled: No module named rospkg

My machine is a generic Ubuntu 16.04 box with Boost 1.58, MuJoCo 131.

I have a question to people who successfully ran the original code: which versions of the OS, the Boost library and the MuJoCo engine do you use?

I did not use the MuJoCo engine, but encountered the same error while installing fresh on a new machine. I think the problem stems from the command "sudo apt-get install libboost-all-dev" which installs an older version than is available from the source code. By installing the latest boost from the source code, I've solved this error.

@burak-cetinkaya Thank you very much for your comment. The master branch works just fine with Ubuntu 14.04, cmake 2.8.12.2 and boost 1.54.

Can I install this under Ubuntu 16.04 ? I have some issue like:

-- Boost version: 1.58.0

Is it relate to the Boost version? Should I change the version?
