This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
not have time to include it here (see ChangeLog).
Significant pkgsrc-related changes:
- ffmpeg plugin now builds (see new SUBST_* declarations). Use
ffmpeg-devel instead of ffmpeg.
- DESTDIR support
- GNU TLS option (enabled by default, evidently used by XML parser (?))
- Include graphics/gd, as its dependencies completely overlap and it
doesn't take too long to build.
- Add x11/libXi to get Xinput functionality.
- Yet another header patch (patch-am)
- TODO file (place reading it on your TODO list today!)
