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

5 years ago 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 3.5.1By 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).
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:

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
