* libXp was used by Xaw8, but it had been obsolated, and in pkgsrc,
x11/libXaw/buildlink3.mk had been switched to pick up Xaw7 by default.
* With x11/xorg-cf-files, libXp was offered with XawClientLibs,
but updated to 1.0.4, it was removed.
* And pkgsrc had been switched to use always xorg-cf-files and imake from pkgsrc,
so all platforms should not require libXp from libXaw with Imake.
Bump PKGREVISION.
or USE_X11BASE set, but don't include mk/x11.buildlink3.mk directly or
via buildlink3.mks
- introduce BUILDLINK_PREFIX.libXpm as alias for BUILDLINK_PREFIX.xpm
in the !modular case
- fix some cases where the check for libX11 couldn't work at all by using
C++ for compilation without including the proper headers
Verified using a full X11_TYPE=xorg bulk build without additional
breakage. Discussed with salo@, wiz@ and send to packages@ for feedback.
