Communication problems with a server [closed]

edit

Dear all,

I need to communicate with a server that is running on my local machine. It is a Verbio TTS server and I have a SDK library which includes all the required functionalities.

When I generate a C++ application where the communication with the server is established and some operation are made, it works well; however, when I create a ROS node with the same code, it compiles well but at runtime the software crashes upon initiating communication.

The ROS node is very simple, because I only want to test the testdemo in a ROS environment. Here are the first few lines of the node:

if (argc>1)

  text = argv[1];

if (argc>2)

  vox_setparm(-1, VXGB_DEFSERVER, argv[2]);

ros::init(argc, argv, "tekniker_tts");

printf("Initializing... \n");

vox_tts_init(0, "es");

After the vox_tts_init call the software crashes.

I have linked the SDK library to the node by adding these lines to the CMakeList.txt file:

rosbuild_add_executable(tekniker_tts src/tekniker_tts.cpp)

target_link_libraries(tekniker_tts voxlib)

Does anyone know how I can solve this problem?

The communication between client and server is established through ports 8764 and 8765. Could it be a problem on ROS environment?

Thanks in advance
