Hi Michael, Thanks for the suggestion, which I had considered and tried already. The problem is that while I can directly include the top-level file, say elfcore.h, the files it includes will come from the host kernel and not the target kernel. Certainly one of the approaches I can take is to maintain a second copy of the target kernel header files that I need access to for this tool, and make sure they include from the target area. I was hoping there was a more 'elegant' solution. You may be right about gcc-help not being the best mailing list, I will pose the question on the gdb list as well.
