See: http://matrix.cpantesters.org/?dist=XS-TCC;os=linux;perl=5.25.7;reports=1#sl=1,1 On the other hand, configuring in a way very similar to the way Dan Collins did in http://www.cpantesters.org/cpan/report/c08895d8-a65f-11e6-932a-f4415c96acb4 (now, a month-and-a-half ago), I was able to reproduce the same test failures. The documentation for XS-TCC states: "This is a highly experimental module. Use at your own risk. Get in touch with the author(s) if in doubt." So perhaps that's what we have to do here. Thank you very much. -- James E Keenan (jkeenan@cpan.org) --- via perlbug: queue: perl5 status: new https://rt.perl.org/Ticket/Display.html?id=130046Thread Previous
