    v82 v124

    77The branch attached to this ticket updates Sage to run on top of
    8 [[https://github.com/markuspf/gap/tree/hpc-merge-libgap|a branch of GAP]]
    9 by Markus Pfeiffer that adds libgap compilation and
    10 [[https://github.com/gap-system/gap/pull/1205|might be merged]]
    11 soon in the devel version of GAP.
    12 
    13 See https://github.com/markuspf/gap/issues/2 for the few sticking points
    14 that could prevent using a vanilla GAP from the distribution (please edit
    15 further if you think about more of them).
     8of a recent GAP master branch, close to the future 4.10.

    1710What the branch does:
    … …  
    4740- Revert #19726 (not needed anymore)
    4841
    49 Status: Most long test pass. Tentatively, the 38 remaining failing
    50 tests are due to changes in GAP since 4.8.6: Max mentioned that the
    51 library has been cleaned up to always use the same random generation
    52 source, and some of the group algorithms were changed as well, which
    53 can explain, e.g. change of orders in lists of elements. So those
    54 should be nothing to worry about. There is not much point in updating
    55 those doctests right away; we may as well wait for a more final
    56 version of 4.9 to be out.
     42Status: currently broken  - crashes deep inside GAP error handling system after few simple commands.
    5743
    5844TODO:
    5945
    60 - Automatic handling of headers (see below for how to do it by hand).
    61   GAP's build system will eventually provide a rule to install headers
    62   which will make this trivial.
    63 
    64 - Use GAP's own `make install` [[https://github.com/fingolfin/gap/issues/44|when it will be implemented]].
    65 
    66 - Check against #19915 to see if any of the changes there should be
    67   ported here. Then close as won't fix.
    68 
    69   - Update doctests as needed
    70 
    7146- ???
