Run roscore error after build in Ubuntu 16.04

[echotor]

I build the apollo-platform in Ubuntu 16.04, and it passed.
But when I run roscore, it outputs the error like below:

Traceback (most recent call last):

Should I solve this problem?
I find the issue like #52 #19
But I can not find a solution for this.

I solve the problem:

1. build and install fast-rtps follow the build.sh in https://github.com/ApolloAuto/apollo-platform/blob/master/ros/third_party/build.sh
2. build and install the apollo-platform
3. build and install _participant.so follow the build.sh in https://github.com/ApolloAuto/apollo-platform/blob/master/ros/third_party/swig_wrapper/build.sh

Then the apollo-platform is built in ubuntu 16.04 successfully.

Hi, have you build apollo-ros in ubuntu 16.04 correctly? I also caught the same error, and follow your hint I fixed the error, but I caught another error as follow when I run any ros command.

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
Aborted (core dumped)

[echotor]

NO, I can run correctly. @wlwu92

@echotor Could you push your Ros source folder to your githbub?
