The ExtUtils::ParseXS module, which does the parsing, was largely rewritten during the Perl 5.44 development cycle, and the new versions consider this a hard error. Building Authen-Libwrap Error: unrecognised line: '/ * EOF * /' in Libwrap.xs, line 32 (possible start of a truncated XSUB definition?) The perlxs documentation in 5.44.0-RC1 has this to say on the subject: An XSUB ends when /\n\n\S/ is encountered: i.e. a blank line followed by something on column one. (This is why it's recommended to indent XSUB-scoped keywords.) If the thing at column one matches any of the items which can appear in between XSUBs (such as file-scoped keywords) then it, and any subsequent lines, are processed as such. Anything starting on column one which isn't otherwise recognised, is interpreted as the first line of the next XSUB definition. In particular it is interpreted as the return type of the XSUB: this can lead to weird errors when something is unexpectedly interpreted as the start of a new XSUB, such as /* */, which isn't valid in the XS half of the file apart from within code blocks. The attached trivial patch makes libauthen-libwrap-perl build with both Perl 5.40 and Perl 5.44. -- Niko Tyni ntyni@debian.org --6bvVJ++yQa4K7L69 Content-Type: text/x-diff; charset=us-ascii Content-Disposition: attachment; filename="fix-xs-comment-syntax.patch" From: Niko Tyni <ntyni@debian.org> Date: Tue, 7 Jul 2026 14:12:41 +0100 X-Dgit-Generated: 0.23-2 1a40c8da2f2aeb4c5f452ddd6a3614eeb315a4e7 Subject: Fix XS comment syntax C style comments are not supported in the XS part, and they cause a hard error with newer versions of ExtUtils::ParseXS (3.63 or so.) --- diff --git a/lib/Authen/Libwrap.xs b/lib/Authen/Libwrap.xs index da197df..8e50bf8 100644 --- a/lib/Authen/Libwrap.xs +++ b/lib/Authen/Libwrap.xs @@ -29,4 +29,4 @@ _hosts_ctl(daemon, client_name, client_addr, client_user) XSRETURN_UNDEF; } -/* EOF */ +# EOF --6bvVJ++yQa4K7L69-- ]
