State of Stubdomains on NetBSD

State of Stubdomains on NetBSD

[tech mailinglists]

[-- Attachment #1.1: Type: text/plain, Size: 248 bytes --]

Hello all,

I read in the wiki that stubdomains aren't support on NetBSD. Will subdoms
be supported on NetBSD? Is someone working on that topic actually?

On the NetBSD Xen mailinglist I got no reply. Hope that someone could help
me.

Best Regards

I see no reason why it should be hard to do it, so it should be just a
matter of someone with a NetBSD box to just try and fix the few missing
bits.

Except that you need a gcc compiler which is able to build mini-os &
such, but I guess this is already the case?  I see that there is already
a -U __FreeBSD__ in the stubdom/Makefile, so it looks like somebody has
already given a try on FreeBSD, and NetBSD shouldn't be very far.

I've given it a look some time ago, but the build of newlib (if I
remember correctly) had dependencies on a bunch of Linux header files
which are not present on NetBSD. I guess a solution would be to ship all
those necessary headers with stubdoms, and use them when needed, but I'm
afraid that will probably crash with headers already present in NetBSD.

Another (and much simpler option) is to compile the stubdomains on a
Linux system and then copy them to your NetBSD system (or fetch them
from a packaged version of Xen from a Linux distro).

Ok, the building will be no problem to do this on a Linux system. But all
is given in the NetBSD Dom0 kernel and Xen to run Stubdoms on NetBSD am I
right?

Dom0 is not really involved when using a stubdom, so be it Linux or
NetBSD should not matter.

Ah?  I don't see why newlib should fetch such header, since we configure
it with target=arch-xen-elf, it's not supposed to assume anything
linuxish.

Yes, this should just work.

It fails to build with 'stddef.h: No such file or directory'.
stddef.h is in /usr/include/ which is not part of the search-path.

This is supposed to be coming from

GCC_INSTALL = $(shell LANG=C gcc -print-search-dirs | sed -n -e 's/install: \(.*\)/\1/p')
TARGET_CPPFLAGS += -isystem $(GCC_INSTALL)include

GCC_INSTALL is empty on NetBSD.

Ok, so that's what needs to be looked at.

I don't follow NetBSD closely but AFAIK while you can't build a stubdom
on NetBSD stubdoms images built elsewhere should work.
