Error When Using Chalkboard in Redhawk IDE Sandbox

I'm trying to test components in the Sandbox using the REDHAWK IDE but I receive an error every time I to drag a component on to the Chalkboard.

For example, when I try to drag the built in SigGen component on to the Chalkboard I get a popup window stating:

'Launching component SigGen_1' has encountered a problem.

Failed to launch: SigGen_1

In the details section it says:

Failed to launch: SigGen_1
IDL:CD/ExecutableDevice/ExecuteFail:1.0

Also, the error in console window depends on the implementation I launch (the error in the pop window remains the same). For Java, no error is displayed in the console window. The errors from C++ and Python implementations are below.

C++

terminate called after throwing an instance of 'CORBA::TRANSIENT'

Python

ERROR:root:Unexpected Error
Traceback (most recent call last):
  File "/usr/local/redhawk/core/lib/python/ossie/resource.py", line 538, in start_component
    rootContext.rebind(name, component_Var)
  File "/usr/lib/python2.6/site-packages/omniORB/COS/CosNaming_idl.py", line 222, in rebind
    return _omnipy.invoke(self, "rebind", _0_CosNaming.NamingContext._d_rebind, args)
TRANSIENT: CORBA.TRANSIENT(omniORB.TRANSIENT_ConnectFailed, CORBA.COMPLETED_NO)

The SigGen component does not even show on the Chalkboard in the IDE.

When I try to launch waveforms in the REDHAWK_DEV domain I don't encounter any problems.

Solution

  • I had the same problem initially. I am running CentOS 6.4 with Redhawk 1.9. I had to add an entry in my /etc/hosts file due to the fact that I named my computer something other than localhost. I just added a line such as:

    127.0.0.1    YourComputersHostName

    to /etc/hosts replacing YourComputersHostName with your computers actual hostname.
