OPAM is telling you that the SAT problem it is trying to solve is too hard. That's happen sometimes unfortunately. If you still have the same state, some useful command for us to try to reproduce the issue:

All the above files are posted as gists now. I hope people find them useful

I dealt with it last time by running
I've pasted the output into gists as below. I'm not sure if my switch is unusual in any way but my next step is going to be to remove the

Amir's cudf files seem to be processed alright by aspcud |
Hi folks, last night I archived my old After that, I thought I'd try installing a lot of packages at once to see what would happen and it seemed to work fine (this downloaded 58 packages).

I just got the same bug :( |
Which solver are you using @jpdeplaix ? |
The default one. |
Really need to port |

I got it to work by setting env variable OPAMSOLVERTIMEOUT=60 the error message in case of timeout could be improved and propose more alternatives. |
It's getting worse. It takes 1 minutes to realize everything is up-to-date

This adds the following data: * the export of an install of the packages as reported by Amir on ocaml/opam#985 (github omd mpp core lwt ctypes utop cow mirari tuntap async yojson core_extended core_bench cohttp async_graphics cryptokit menhir), with the repo as of 2013-12-01 * a current tar-gz of the packages/ dir of the repo Using those it will be easy to replay the upgrade scenario. Currently, it's instant with aspcud, and I could'nt have it succeed with the internal heuristic. Remains to add an automatic test of this in the tests.
Marking as 1.2 as it is mostly independent of the release, but too important to close. |
This is related to ocaml#985
Is the source to aspcud available somewhere (for those of us not on Debian)? |
If you're on Mavericks then the aspcud solver is the default/recommended one. Just If you really want source is the following helpful? (NB I haven't downloaded to check) http://sourceforge.net/projects/potassco/files/aspcud/ |
I'm on Fedora. Just trying to find the source as there is no aspcud package on Fedora so I want to build from source. |
@philtomson -- easiest way is probably to follow the MacOS X Homebrew port and dependencies: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/aspcud.rb This has aspcud (and source and patches), and you'll need the build dependencies too (clasp and gringo). If you're feeling brave, a few spec files for Fedora would be gratefully received :-) |
Dear Phil, https://sympa.inria.fr/sympa/arc/caml-list/2014-01/msg00047.html The source code for aspcud is availabe on sourceforge, the released version 1.8 http://sourceforge.net/projects/potassco/files/aspcud/1.8.0/ Instructions on how to build is here: http://sourceforge.net/p/potassco/code/HEAD/tree/tags/aspcud-1.8.0/INSTALL Notice that there is a new version in the works, to be released soon, that Thanks a lot for volunteering, and if you need help from upstream, Roberto On Thu, Feb 06, 2014 at 10:30:17AM -0800, Phil Tomson wrote:

Superseded by #1267 |
I'm on the HEAD version of opam (I just did
brew reinstall opam --HEAD
) and tried to update my packages as I haven't done this in a while. Opam upgrade didn't appear to do its thing and then suggested I downgrade a bunch of packages.This doesn't seem like normal behaviour and below is the output. Please let me know if I can provide something more specific.
