Thanks for reporting, It's fixed on svn trunk.

That's already very informative. Clearly the tab-completion got somewhere a
null pointer.
I hope that you understand that the 'cd' must include a component name and not
a filename (it could have been called 'change component' - 'cc' instead of
'cd'). For now, you'd better avoid completing on file names until we found the
fix.

Hi.

Problem description:
I am following the RTT-exercises and I got a segmentation fault on hello-7-deployment. I succesfully compiled both the hello- and world-xenomai.so. I added the import line to the application.xml. I run the deployer using $ sudo deployer-xenomai -linfo -s application.xml (the hello component has not been loaded at this stage), but when I type "cd Hello.cpp" and press tab (autocomplete), I inmediately get "Segmentation fault". If I type "cd World.cpp" and press tab, I get no segmentation fault.

However, if after a "make clean" (world-xenomai.so is deleted) I try "cd World.cpp" + tab, I do get a segmentation fault. I tried to "cd" to other files, and apparently filenames with a "." in the middle produce this error. A file inside the Debug subdirectory do not result in segmentation fault even if it has a "." in its the middle of its name.

The system:
Ubuntu 9.10, xenomai 2.51, rtt 1.10.2.

What other info do you need to track this?

Regards,
