Hi, the problem with Debian gprolog is that it's based on an experimental branch (modules), which is incomplete and is the cause of the bug.
The fix may be as simple as getting the regular upstream and recompiling it. I'm a bit confused with the git-based packaging tools, so maybe I should revert to a plain packaging build... Give me a couple of days to try that path first. best, -salvador > On 10 Mar 2019, at 22h49, Cedric Ware <cedric.ware__...@normalesup.org> wrote: > > > Hello Tony, > > tony mancill (Sunday 2019-03-10): >> I had a try at this.
