Ahh, that explains it. I did a little bit of a dirty hack in r336026 to install the needed libnv headers with libnv- otherwise, we'd still be relying on the host libnv headers since sys/ bits don't normally get pulled in with `make includes` (from the look of it). It feels wrong to have a userland lib installing headers into ${INCLUDEDIR}/sys, but I think that's a libnv problem. This should fix the observed problem with CI for the time being. _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
