[opam-devel] opam 1.1.1 and aspcud 1.9

[Roberto Di Cosmo]

Thanks Louis for looking into this. 

As for aspcud 1.9, I also have trouble understanding what the issue could be.
The version in utopic [1] is exactly the same as the one I use in Debian [2],
and it is backward compatible with 1.8: the old preference criteria are still
there, just do

  $ /usr/local/bin/cudf2lp --help

and you will see this text among the rest

  --criteria,-c <arg>  : Preprocess for specific optimization criteria
      Default: none
      Valid:   none, paranoid, trendy, -|+<crit>\(,-|+<crit>\)*
        <crit>: count(<set>) | sum(<set>,<attr>) | unsat_recommends(<set>)
              | aligned(<set>,<attr>,<attr>) | notuptodate(<set>)
        <attr>: CUDF attribute name
        <set> : solution | changed | new | removed | up | down
              | installrequest | upgraderequest | request
      For backwards compatibility: 
        new              = count(new)
        removed          = count(removed)
        changed          = count(changed)
        notuptodate      = notuptodate(solution)
        unsat_recommends = unsat_recommends(solution)
        sum(name)        = sum(name,solution)

Anil, may you provide a more precise bug report?

Where we have been hitting problems on Debian was by compiling with a different version of *Dose* [1] (which has a much less standardised interface).
