Error with building custom bullet3

[hzyjerry]

Hi,

I tried installing the custom bullet3 with pip3 on mac, and ran into this issue error: command 'gcc' failed with exit status 1.

So I tried cloning from the custom bullet3 repo, and building from there using ./build_cmake_pybullet_double.sh. I ran into this following error:

/Users/jerry/Dropbox/Projects/AssistRobotics/bullet3/test/SharedMemory/./test.c:58:10: error: no matching function for call to 'b3PhysicsParamSetGravity'
                        ret = b3PhysicsParamSetGravity(command, gravx, gravy, gravz);
                              ^~~~~~~~~~~~~~~~~~~~~~~~
/Users/jerry/Dropbox/Projects/AssistRobotics/bullet3/test/SharedMemory/../../examples/SharedMemory/PhysicsClientC_API.h:326:20: note: candidate function not viable:
      requires 5 arguments, but 4 were provided
        B3_SHARED_API int b3PhysicsParamSetGravity(b3SharedMemoryCommandHandle commandHandle, double gravx, double gravy, double gravz, int body);
                          ^

Looks like int body is causing conflicts with the example code. Have you run into this issue before? Thanks for your insight.

Update: I was able to bypass the problems by installing on Ubuntu. The issue with Mac remains.

Hi Jerry!

What version of Python are you running on your Mac? One suggestion is to switch to Python 3.6 (e.g. 3.6.5) using pyenv local install.
