It sounds like you installed = the latest version using OPAM, so you should use the HEAD of the tutorial.

It's already shown that we probably need special support for 'opam = install *', as the issue with doing 'opam install `opam list -short`' is = that some packages have a compiler-version constraints, but are still = listed, which causes the whole mass installation attempt to fail. Since opam-trunk appears to be broken atm, I've temporarily pointed it = at the Mirage forks of OPAM on github.

I really don't like this binary bootstrap of OPAM, as it's always going to be quite = unreliable. Instead, if you get the tarball manually: $ curl -OL https://github.com/OCamlPro/opam/tarball/0.7.5 $ tar -zxvf 0.7.5 $ cd OCamlPro-opam-954f6a5 $ ./configure && make && sudo make install $ opam init One important thing before you proceed: you need to install the native code versions of the OCaml compiler for this to work (at least until [1] is fixed). If you are on Debian, these are the 'ocaml-native-compilers' package, or if you installed OCaml from source, do 'make world.opt' = before you do a 'make install'.

I wonder if this is because you have ocamlfind installed in your system already. Could you uninstall all the 'global' OCaml packages = (particularly findlib), then delete ~/.opam, and do an 'opam init' from scratch? Thomas: this may be the ocamlbuild/findlib detecting = /usr/local/bin/ocamlfind instead of the PATH default, that we ran into in OUD too.

I can run it locally just fine and other computers on my network can connect to it. I roughly followed the instructions on the wiki (http://www.openmirage.org/wiki/xen-boot) and after tweaking the script slightly, I'm able to bundle, unload, and boot up and ec2 instance with a mirage kernel. The instance launches just fine and I can see output from various mirage systems in the ec2 system log output. However, when I try to connect to my ec2 host (after opening port 80 in the ec2 console), my web browser just hangs. Any ideas?

...and this will pick up an IP address on EC2.

If you've run it locally, did you already make this change? =C2=A0Doing= an
auto-update of mirage-www to EC2 is on my todo list, so I'll check
manually tomorrow if it works with the latest trees or not. Dave, have
you tried this recently?

Have you opened up the firewall on EC2 correctly? This bit can be
a bit confusing, as you need to specifically open up port 80 when you
create the VM. =C2=A0It doesn't always work me if I reconfigure this af= ter
the VM starts...

To the bes= t of my knowledge, I've got port 80 open with Amazon (sorry for the scr= eenshot, I couldn't figure out which ec2 command line tool gave me the = same info). I opened those ports in the default security group before this = instance was created.

I could be doing something really dumb though--like I said, = I'm pretty new to all these moving pieces.

Have you opened up the firewall on EC2 correctly? This bit can be
a bit confusing, as you need to specifically open up port 80 when you
create the VM. =C2=A0It doesn't always work me if I reconfigure this af= ter
the VM starts...

SO if you update your mirage/mirage-net to the latest rev by:

$ opam update
$ opam upgrade

And then recompile mirage-www, it should work now. =C2=A0I tried this on a = local

You can find out more about it here: http://www.openmirage.org/wiki/tutorial-lwt ...along with some tutorials that work on Mirage (using the monolithic version, but the principles are the same). You can find out more at the homepage as well: http://ocsigen.org/lwt However, if you are learning OCaml from scratch, you should learn the = basics first. We're working on an O'Reilly book due early next year, but the = best currently available text is: http://files.metaprl.org/doc/ocaml-book.pdf ...as well as: http://caml.inria.fr/pub/docs/oreilly-book I'd encourage you to build simple servers using the tutorials there, and then move onto Mirage once you are a little more familiar with the = basics. Feel free to ask any specific question on this list. We are indeed planning to refresh the tutorial before the first beta release, and that'll probably happen in November sometime when I'm back. best, Anil On 13 Oct 2012, at 10:07, Yiming Zhang wrote: > Hi, Anil >=20 > Thank you for your suggestions.

I am new at the board, so excuse me if I ask trivial questions.

I installed Mirage using opam following the instructions found at
http://www.openmirage.org/wiki/install

My system's details are:
  Ubuntu 12.04.1 LTS
  3.2.0-32-generic 64bit
  The Objective Caml toplevel, version 3.12.1
  opam version 0.7.7
  (haven't installed Xen yet)

I do not want to install bins/libs under the default Linux path ( usr/{lib/bin} ) because I do not want to grant root privileges to the installers.

As a point of start I aim to run the mirage wiki website locally via the www-mirage package, through Unix binaries ( compiler 3.12.1+mirage-unix-direct ).

However, when I run "opam --verbose install mirage-www" without sudo, the installation fails while trying to install mir-run at "/usr/local/bin/mir-run".
I've seen that the default PREFIX in most mirage-related Makefiles is /usr/local (requiring root privileges).

In order to fix that issue, I export a custom prefix path before I proceed with the installation (e.g. export PREFIX=/data/bin).

Have I mis-configured Mirage during installation or the path /usr/local is the default hard-coded installation path for certain packages?

There was a bug a while back that would = cause mirage-platform to install a script into /usr/local (the `mir-run` = script). I fixed that, and current opam should work. However, there's a small quirk to be aware of. The opam package manager = remotes pointing to git:// urls might not be refreshed unless you do: $ opam pin mirage-platform git://github.com/mirage/mirage-platform $ opam update $ opam upgrade Do you want to try this and let me know if the error still persists? cheers Anil On 29 Oct 2012, at 14:54, Dimosthenis Pediaditakis = wrote: > Hi everyone, > I am new at the board, so excuse me if I ask trivial questions. >=20 > I installed Mirage using opam following the instructions found at > http://www.openmirage.org/wiki/install >=20 > My system's details are: > Ubuntu 12.04.1 LTS > 3.2.0-32-generic 64bit > The Objective Caml toplevel, version 3.12.1 > opam version 0.7.7 > (haven't installed Xen yet) >=20 > I do not want to install bins/libs under the default Linux path ( = usr/{lib/bin} ) because I do not want to grant root privileges to the = installers. >=20 > As a point of start I aim to run the mirage wiki website locally via = the www-mirage package, through Unix binaries ( compiler = 3.12.1+mirage-unix-direct ). >=20 > However, when I run "opam --verbose install mirage-www" without sudo, = the installation fails while trying to install mir-run at = "/usr/local/bin/mir-run". > I've seen that the default PREFIX in most mirage-related Makefiles is = /usr/local (requiring root privileges). >=20 > In order to fix that issue, I export a custom prefix path before I = proceed with the installation (e.g. export PREFIX=3D/data/bin).=20 >=20 > Have I mis-configured Mirage during installation or the path = /usr/local is the default hard-coded installation path for certain = packages? >=20 > Regards, > Dimos >=20 --Apple-Mail=_EBE7138F-593F-4564-AEF7-E4A2D9EE25BC Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset=iso-8859-1 git://github.com/mirage/m= irage-platform

Do you want to try this and let me know = if the error still = persists?

Hi everyone,
I am new at the board, so excuse me if I ask trivial questions.

I installed Mirage using opam following the instructions found = at
http://www.openmirage.org/= wiki/install

My system's details are:
  Ubuntu 12.04.1 LTS
  3.2.0-32-generic 64bit
  The Objective Caml toplevel, version 3.12.1
  opam version 0.7.7
  (haven't installed Xen yet)

I do not want to install bins/libs under the default Linux path ( usr/{lib/bin} ) because I do not want to grant root privileges to the installers.

As a point of start I aim to run the mirage wiki website locally via the www-mirage package, through Unix binaries ( compiler 3.12.1+mirage-unix-direct ).

However, when I run "opam --verbose install mirage-www" without sudo, the installation fails while trying to install mir-run at "/usr/local/bin/mir-run".
I've seen that the default PREFIX in most mirage-related Makefiles is /usr/local (requiring root privileges).

In order to fix that issue, I export a custom prefix path before I proceed with the installation (e.g. export PREFIX=3D/data/bin).

Have I mis-configured Mirage during installation or the path /usr/local is the default hard-coded installation path for certain packages?

Regards,
Dimos
