pack_install - requires(prolog:c_cxx) in pack.pl causes crash #1312

Open kamahen opened 2 weeks ago

kamahen commented 2 weeks ago

I get the following when doing a local install. The problem goes away when I remove the line

requires(prolog:c_cxx).

Note that pack.pl also contains the line requires(prolog >= "9.3.8"). SWI-Prolog version 9.3.10-12-g9614a9b3a-DIRTY

  Install space as symlink to /home/peter/src/space/

You can assign this bug to me -- I intend to look into it as part of my review of the pack documentation and code. (The problem showed up when I updated the packages hdt and space.)
