Hi,
I was trying to enable kgdb for ixp425 (I've been using snapgear 3.2.3
release).
And I got same compilation error which is reported in this mailing list
earlier :
http://readlist.com/lists/uclinux.org/uclinux-dev/0/4974.html
I used __ASSEMBLY__ to guard the C declarations as suggested in reply to
above query.
http://readlist.com/lists/uclinux.org/uclinux-dev/0/4975.html
It proceeded to and got stuck up at linker. The error messages are:
