Hello list,
Could somebody tell me why I can't "list" the source code of this kld?
I built the module with COPTS=3D-g, it is loaded in the kernel and I run =
kgdb in=20
/usr/obj/...../MYKERNEL. Everything seems to go well, except kgdb still=20
doesn't like it. However if I run kldsyms, it only loads acpi.ko.debug an=
d I=20
can list it.
Thank you in advance,
Jerry

Type 'getsyms' after connection to load kld symbols.
If you're debugging a local system, you can use 'kldsyms' instead
to load the kld symbols. That's a less obnoxious interface.
