Cannot build on CentOS 6.5 #230

Closed piffio closed 10 years ago

piffio commented 10 years ago

I'm trying to get into MirageOS by following the instructions / tutorial on http://openmirage.org

I was trying to build the mirage-www package on a CentOS 6.5 VM, and this is the error I get into:

I tried to install the conduit package, but it fails rebuilding the mirage-console-unix.1.0.0 package due to what I believe is an incompatibility with mirage-types-2.0.0 that seems to be required by conduit.

Hi, Thanks for the report!

The console interfaces pulled in by [mirage/mirage-dev] got a bit out of sync. I think this has been fixed by

When I did a clean install and rebuild of mirage-www, I hit one more issue:

As a temporary workaround, try tweaking the config.ml as follows:

$ git diff

djs55 commented 10 years ago

Oh I should also say: be careful doing an 'opam update' 'opam upgrade': normally this would work but there is a bug in the mirage-console remove step. Sometimes it leaves a package behind. If this happens you should be able to manually run

ocamlfind remove mirage-console

to get rid of the leftovers.

piffio commented 10 years ago

Thanks for your comments.

Looking at your but report I see that you are running mirage-console-unix.2.0.0. I do I manage to install this version? Should I do it through opam or through a completely different mechanism?

Sorry if the question might sound silly, buy I'm just getting started with both oCaml and Mirage

piffio commented 10 years ago

Ignore my last comment.

After an opam update && opam upgrade I ended up with mirage-console-unix.2.0.0 being succesfully installed, and now mirage-www is building succesfully.

Still, I had to manyally remove a mirage-console dir as you mentioned in your previous comment.

Thanks!

There's some fallout from recent changes on the development branch. Just to confirm, whats the output of running "opam remote"? I'm testing some fixes to the packaging that should restore the dev branch to a working state shortly.

in the meanwhile, you can satisfy the dependencies manually by "opam install tcpip"

Unfortunately after multiple retries, I'm still unable to build the mirage-www module. Manually installing tcpip didn't help either, since it was in fact already installed (check the output of opam list in the previous post).

Now for some reason when I try to do opam update && opam upgrade it tries to install mirage.1.3.0, and then the compilation fails on some other components, as you can see below:

I'll try cleaning up the whole environment and rebuilding, but I believe that there is still something wrong in the mirage-dev repo. Let me know if you can manage to fix it

piffio commented 10 years ago

OK, ignore everything. I've removed the whole ocamlbrew directory from my home page, starded over with a fresh install of all the packages and now I can suffesfully build the mirage-www module, and move forward!

Thanks for being so reactive!

avsm commented 10 years ago

Excellent! I've just fixed up some minor build issues and confirmed that mirage-www builds for me locally in both Unix and Xen mode.

piffio commented 10 years ago

I just realized I can't build the --xen target, but only the Unix process version. CentOS 6.5 comes with gcc 4.4.7. When I try to run mirage configure --xen I get an error while compiling mirage-xen-minios.0.4, with the following message:

### stderr ###
# ...[truncated]

# make: *** [build] Error 2

It looks like the no-tree-loop-distribute-patterns flag is not supported in my gcc version.

What is the recommended/supported gcc version? Should I just use a different VM, like an ubuntu 14.04 / 14.10?

piffio commented 10 years ago

Just tried building in CentOS 7. The fun thing here is that I can succesfully build the --xen target, due to CentOS shipping gcc 4.8.2, but building the --unix flavor fails with the following error:

File "main.ml", line 56, characters 32-39:
Error: Unbound module OS
Command exited with code 2.
make: *** [main.native] Error 10

At the moment is not very urgent on my side, since I can use a combination of CentOS 6.5 and 7 to build both flavors, but I'm reporting this anyway, in case it is something that needs to be fixed in mirage's code

djs55 commented 10 years ago

The "Unbound module OS" failure looks like: [mirage/mirage#303]. I think the fix for this has been merged a few hours ago -- worth trying a quick 'opam update' 'opam upgrade' and retry?

Now both target are succesfully built on CentOS 7. Thank you!
