make c-stubdom returns No rule to make target `mini-os-x86_64-c'

make c-stubdom returns No rule to make target `mini-os-x86_64-c'

[Andrew Stuart]

Hello

I am trying to make the c example stubdomain but it’s not working.  Here’s what I am doing, any help valued:

thanks


root@contiki:/home/larsr/xen-4.4.2/stubdom# tail -n18 README


                                Your own stubdom
                                ================

  By running

cd stubdom/
make c-stubdom

  or

cd stubdom/
make caml-stubdom

  you can compile examples of C or caml stub domain kernels.  You can use these
and the relevant Makefile rules as basis to build your own stub domain kernel.
Available libraries are libc, libxc, libxs, zlib and libpci.
root@contiki:/home/larsr/xen-4.4.2/stubdom# cd stubdom

root@contiki:/home/larsr/xen-4.4.2/stubdom# make c-stubdom
make: *** No rule to make target `mini-os-x86_64-c', needed by `c-stubdom'.  Stop.

Stubdom's build environment is not very user friendly.

I would suggest you just build stubdom the "usual way", and then extract
the resulting files you need.

And may I ask why would you want to work on 4.4.2 release? If you want
to use stable release you can use 4.5(.1?). And if you feel adventurous
you can use xen-unstable.

Hi Wei

Thanks for your reply.  Forgive me but I’m new to this. What do you mean by 'just build stubdom the "usual way", and then extract
the resulting files you need.’  What is the usual way and which are the files I need?

Actually maybe I could ask you also a more specific question. I have a C application that I wish to run under minios. It is an embedded web server. I’m finding it chalenging to work out where to start to get it compiled as a minios domain.  Can I ask for some general guidance please an how to approach this task?  I’m struggling a bit right now to work out how to pull the C application into minios.

And yes I have now download unstable.

Sorry to be asking questions about things that are probably obvious but I’ve spend alot of hours on this and I’m getting an understanding I think but still a bit lost.

thanks

Andrew

Please don't top-post.

Oops, sorry I was vague.

What I normally do is to stay in top level directory of the source tree,
run ./configure and then run make -- stubdom should be built by default.
But the C stubdom is not built by default. :-/

So in order to build c-stubdom, you need to enter stubdom directory and
run ./configure --enable-c-stubdom. You should see in the output
c-stubdom will be built.

Stubdom is mini-os + libc + all other libraries your application needs.
Yes, it's going to be an exercise. You need to wire up stubdom's
Makefile. There are existing examples in stubdom. You can try your luck.

Another way to achieve your goal is to try "rump kernel". It's still
under development but the build system is a bit nicer to work with than
our in-tree stubdom build system IMHO.

Both solutions will require some work. I can't tell for sure how much
work is required.

One thing to note is that mini-os has been extracted to an external tree
in xen-unstable. The build system will clone it on the fly. It's
supposed to work out-of-box but in case you have problem you at least
have a clue about what is going on.

No they are not general obvious. No need to be sorry.

But I think we can safely(?) say that work done on rumpkernel will be a
more worthwhile investment, while work on stubdom would be more of a
sunk cost...

Yes, that's right.

I can't speak for "stubdom", but I sure hope that work done on rump 
kernels is a worthwhile investment ;)

One thing I'd like to note, though.  While we certainly welcome users 
and contributors already, until someone manages to get around to 
whacking the build system enough to support an "install toolchain" 
feature, it is unclear which bits in the build directory are meant to 
remain stable and which ones just happened to be there at $t.  If 
someone wants to build systems and wants to depend on feature $x 
remaining to be present, for now it's better to ask on the list.

OK I’ll head in the rump kernel direction.  Is this where I should start?
