I compiled gdb but it seems to lack remote vxWorks debugging support (even though its --target is powerpc-wrs-vxworks). Looking through the mailing list archives I couldn't find a difinitive answer but I can guess that remote support was removed from gdb after WindRiver changed the debugging protocol they used.

I suppose I can get a copy of the source from WindRiver, as (I believe) their debugger is based on GDB and is thus GPL'd. I know there's something called tgtsvr though and I don't know what that does and what the license terms are for that program. I also don't know if it is a necessary component of the debugging toolchain or if it is only there in case one needs added features.
