Mirage tutorial errors

["Yiming Zhang" <sdiris@xxxxxxxxx>]

Thanks Anil for the suggestions. I followed the instructions from
http://www.openmirage.org/wiki/install and have successfully run the UNIX
binary of mirage-www. I then cloned the tutorial from
git://github.com/mirage/mirage-tutorial and roll it back to last year (# git
reset b8efbd; # git checkout -f HEAD), but when I 'cd slides && make', the
following errors happened. What's the problem?

*******************************************
root@debian:~/old/mirage-tutorial/slides# make
./scripts/build_socket_crunch.sh
+ BIN=crunch_server
++ which mir-run
+ MIR_RUN=
make: *** [run-socket_crunch] Error 1
*******************************************

I also noted that there are two mirage-tutorials as well as mirage-wwws,
respectively in git://github.com/mirage/XXX and git://github.com/avsm/XXX.
To my understanding, the latter is for the monolithic version, right? 

Thank you for your help!
Yiming

Hi Yiming,

The best way to learn about this stuff is just to get stuck in, hit bugs,
fix them along the way, and ask questions along the way. Documentation will
take some time to get up to the level where a casual user can pick this up,
and actually learning all the components is a very useful way to get up to
speed.  Having said that, we've made great progress on making all of this
usable recently, thanks to Thomas' hard work on OPAM and the packaging
infrastructure.

So I'd suggest you get mirage/mirage-www or mirage/mirage-tutorial compiling
for you and make sure you can get the website up and running locally on your
computer.  The instructions on:
http://www.openmirage.org/wiki/install

should be correct for this already. Just follow them to get an environment
and then clone the mirage-www repository, type in 'make', and run the
resulting UNIX binary.

With the Xen backend, you will get a microkernel that can run under Xen as a
normal VM.  Have you got a working Xen installation available?
