Re: Mirage Hello World (Re: Building mirage-www)

Hi Richard,

I finished the rest of installation steps from http://openmirage.org/wiki/install :

"To go a step further, and develop unikernels that will run as POSIX processes but using the Mirage network stack, switch to a new compiler instance and install the mirage-net-direct package instead:"

Then, the final steps of "First Steps" at http://openmirage.org/wiki/hello-world were followed:

Cleanup with:
$ make clean-basic

To rebuild this as a Xen VM, simply opam switch and rebuild:

$ opam switch 4.00.1+mirage-xen
$ eval `opam config env`
$ make build-basic

I encountered this error:

$ make build-basic

### basic: configure
cd basic && mirari configure --unix
/bin/sh: 1: mirari: not found
make: *** [configure-basic] Error 127

A look at ~/.opam/mirage-xen/bin:

$ ls -l ~/.opam/mirage-xen/bin | wc -l
$ ls -l ~/.opam/mirage-xen/bin/mi*
-rwxrwxr-x 1 phiho phiho 1112728 Sep  5 23:19 .opam/mirage-xen/bin/mirari

and then  ~/.opam/4.00.1+mirage-xen/bin

$ ls -l ~/.opam/4.00.1+mirage-xen/bin | wc -l
$ ls -l ~/.opam/4.00.1+mirage-xen/bin/mi*
ls: cannot access .opam/4.00.1+mirage-xen/bin/mi*: No such file or directory

I know I have missed something here.

Thank you for your help.

ah-- sorry. there appears to be a bug in the mirage-unix OS.Console where the console never gets flushed. i have a (probably rather simplistic) patch for this that i forgot to submit a PR for after returning from USENIX SEC. i'll do that now.

no-- mirage has several package dependencies but these are captured by opam, and will be installed when you "opam install mirage-{xen,unix}" etc. i don't believe there's an "RWO" package or similar to install.
