I need some help. I'm trying to fix a GCC warning by modifying the
struct dev_ops in device/conf.h. I need the definition of io_req_t
to do that. But when I include device/io_req.h from device/conf.h
the build breaks with this error message:
In file included from ../vm/pmap.h:45:0,
from ../vm/vm_object.h:49,
from ../vm/vm_page.h:40,
from ../device/io_req.h:41,
from ../device/conf.h:35,
from ../device/dev_hdr.h:64,
from ./machine/io_perm.h:26,
from ../i386/i386/tss.h:32,
from ../i386/i386/thread.h:43,
from ./machine/db_machdep.h:37,
from ../ddb/db_access.c:34:
../kern/thread.h:81:2: error: unknown type name "pcb_t"
gnumach has been configured with --enable-kdb.
kern/thread.h already includes i386/i386/thread.h which defines the
pcb_t, so I don't understand why GCC fails with this error message when
everything is OK.
Does anybody have any idea what is happening?
