Because your project is a QNX C Project, you need to run it as using QNX qconn configuration. Following are the step to 
run it:

1) You need to have a separate machine (called target) running QNX Neutrino O.S., run the "qconn" utility in this target
 machine.
2) In you IDE, create a QNX Target project, enter the same IP address as your target machine. 
3) Select the build output binary in your project and select "Run as -> C/C++ QNX QConn". This will open a run 
configuration dialog window.
4) Make sure you have the correct target selected, and optionally you can enter additional configuration data like 
command arguments and environment variables.
5) If you want to debug your binary, do the same things as above except to select "Debug as -> C/C++ QNX QConn".
