I have Redhawk 1.9 loaded on a 32-bit CentOS 5 virtual machine. I am trying to run the Redhawk HelloWorld component described here: http://redhawksdr.github.io/Documentation/mainch3.html. I am able to launch and start the component in the eclipse sandbox. I cannot run it from Python though. I get the following error.

Python 2.7.2 (default, Feb 27 2012, 16:40:29) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from ossie.utils import sb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/redhawk/core/lib/python/ossie/utils/sb/__init__.py", line 115, in <module>
    from domainless import *
  File "/usr/local/redhawk/core/lib/python/ossie/utils/sb/domainless.py", line 102, in <module> 
    from omniORB import CORBA, any
ImportError: No module named omniORB
>>>

Any ideas why it will not work?

    at a guess you need the omniOrb python module ... – Joran Beasley Jan 09 '14 at 20:54
  • My bet is that the Eclipse sandbox mucks about with your PYTHONPATH either at the shell or by manipulating `sys.path`. I'd try digging around the Redhawk docs and source, or just probing things like `sys.path` and `sys.modules` while in the sandbox to see what's going on. – Silas Ray Jan 09 '14 at 20:57

You'll probably have to set your PYTHONPATH manually to include the appropriate directory. It looks like Eclipse is doing that for you.

Try running your example as root. If you can successfully run as root, then you have a permission problem on your directories or files. How do you identify the files that have the incorrect permission ? I ran the following command, strace -o test.out python -c "from ossie.utils import sb"

This command will write the output to test.out. Look for the string "denied", which will identify the file that has the incorrect file permission.
