Can't run it in Linux

[axi345]

I used Ubuntu 14.02 and Anaconda with Python 3.5.2 to run this project. I downloaded this repository and run these commands:

cd MAgent sudo apt-get install cmake libboost-system-dev libjsoncpp-dev libwebsocketpp-dev bash build.sh export PYTHONPATH=$(pwd)/python:$PYTHONPATH

But there raised some errors and I couldn't install the python package successfully. So I copied the file "Magent" to my python project and used pycharm to mark the "Python" file in it as the Sources Root. When I run the file "api_demo.py", it showed some error massages:

/home/sean/anaconda3/bin/python3.6 /home/sean/DRL/MAgent/examples/train_pursuit.py Traceback (most recent call last): File "/home/sean/DRL/MAgent/examples/train_pursuit.py", line 11, in import magent File "/home/sean/DRL/MAgent/python/magent/init.py", line 2, in from . import utility File "/home/sean/DRL/MAgent/python/magent/utility.py", line 12, in from magent.builtin.rule_model import RandomActor File "/home/sean/DRL/MAgent/python/magent/builtin/rule_model/init.py", line 2, in from .rush import RushPredator File "/home/sean/DRL/MAgent/python/magent/builtin/rule_model/rush.py", line 7, in from magent.c_lib import _LIB, as_int32_c_array, as_float_c_array File "/home/sean/DRL/MAgent/python/magent/c_lib.py", line 42, in _LIB = _load_lib() File "/home/sean/DRL/MAgent/python/magent/c_lib.py", line 21, in _load_lib lib = ctypes.CDLL(path_to_so_file, ctypes.RTLD_GLOBAL) File "/home/sean/anaconda3/lib/python3.6/ctypes/init.py", line 348, in init self._handle = _dlopen(self._name, mode) OSError: /home/sean/DRL/MAgent/python/magent/../../build/libmagent.so: cannot open shared object file: No such file or directory

Process finished with exit code 1

It seems that my file miss some resources. But I use files completely copied from git. Maybe I missed some steps. I need some help to use the repository. o_o

It seems that the build process was failed and thus libmagent.so did not exist. Can you provide the build messages as well?

Thank you for your reply.

The build log shows that your C++ compiler does not support LLVM and hence the compilation cannot be completed. You may manually upgrade your C++ compiler and rebuild the project.

You may also refer my environment:

$ uname -a

$ g++ --version

$ cmake --version
cmake version 3.5.1

By the way, I've also seen that you have not installed websocketpp which is not released on Ubuntu 14 so I am afraid that it would be annoying to build MAgent (refer here).
