The first error is: /home/rjones/d/fedora/polymake/rawhide/polymake-4.10/lib/core/src/perl/RefHash.xxs:737:11: error: ‘Perl_ck_fun’ was not declared in this scope; did you mean ‘Perl_cx_dup’? 737 | return Perl_ck_fun(aTHX_ o); | ^~~~~~~~~~~ | Perl_cx_dup ninja: build stopped: subcommand failed. As far as I can see that's the only missing / hidden Perl symbol. This symbol was hidden in: https://github.com/Perl/perl5/commit/0351a629e71de127cbfd1b142e9eaa6069deabf5 As for what it does, that's more tricky. I believe what it's doing is while Perl is parsing the input script, it is used to check that the thing you are calling is a function. Unfortunately it's slightly more complicated than that because it can convert some function-like things to functions (returning the updated OP*). Also Perl_ck_fun is complicated, to say the least: https://github.com/Perl/perl5/blob/a6d10131eee6ee336e4bd63f22a378e9d5ae40bd/op.c#L12522 For these reasons we can't just replace 'return Perl_ck_fun(aTHX_ o)' with 'return aTHX_ o', nor can be copy the function into the polymake source (since it calls other internal functions, but also for licensing reasons). So I think this does require upstream attention. Another note is this package requires ocaml-tplib which we orphaned. Rich. > > Rich. > > > > > Polymake upstream is aware of the issue.
