Thanks so much, looks like things are partway there... Just pulled the gdb that you uploaded to the T6 repo. In starting gdb from the command line I see an error that the shared library libtinfo.so.5 could not be loaded as it could not be found.
On another note, just before I found your note, after several tries, I was able to build gdb-7.8.2 from source... I used a bash shell to do the build. I remembered that compiletc loads the build tools, I obtained the texinfo and ncurses packages from the TC6 repo. I had ncurses install onboot.
I'm a bit suspicious of what I have so I built a simple hello world program and see it in the command line version of gdb which is encouraging. I also gave the gdb text-user interface a try. While it doesn't immediately show the source, right after I hit return, the source showed right up... Anyone have a favorite graphical tool for use with gdb?
I have my TC system in a USB memory stick and built gdb there, so for now I can do a "make install" but that takes some time. I'm not sure how to package that up...
