Hi everyone,

I have used rosserial_windows to connect my laptop in windows to a pc in ubuntu and sending some sensor data from windows to linux. Now i need to build the .dll of the rosserial_windows and i used the below but i get the LNK error. i would appreciate any help.

extern "C"

ros::NodeHandle nh;
char *ros_master = "";
std_msgs::Float32 roll_msg;
ros::Publisher roll_pub ("roll", &roll_msg);

  __declspec(dllexport) void InitRosPublish()
    nh.initNode (ros_master);
    nh.advertise (roll_pub);

  __declspec(dllexport) void PublishImuData(double roll, double pitch, double yaw)
  { = roll;
        nh.spinOnce ();
        Sleep (10);

  __declspec(dllexport) void Sum(double a, double b, double& c)
      c = a + b;

Edit: Actually i have to add that the first error is:

Error   2   error LNK2019: unresolved external symbol "public: void __thiscall WindowsSocket::init(char *)" (?init@WindowsSocket@@QAEXPAD@Z) referenced in function "public: void __thiscall ros::NodeHandle_<class WindowsSocket,25,25,512,512>::initNode(char
