problems building kdenetwork

I'm having trouble trying to build kdenetwork:

/usr/pkgsrc/net/kdenetwork3/work/.buildlink/include/X11/Xmd.h:152: error: confli
cting declaration 'typedef long unsigned int CARD32'
../../krfb/libvncserver/rfb.h:43: error: 'CARD32' has a previous declaration as 
'typedef unsigned int CARD32'
rfbcontroller.cc: In member function 'virtual void KNotifyEvent::exec()':

This is on a i386-4.x machine running xorg.  I refreshed pkgsrc from HEAD,
used lintpkgsrc to find out what packages were out of date, and pkgdepgraph
to generate a rebuild script.  Everything but kde3 rebuilt without
any trouble.

/usr/pkg/include/X11/Xmd.h comes from xproto, which seems to be
a dependency of kdenetwork3, though I don't see just where it's
being requested.

As part of a two-week-long pkg_rolling-replace I rebuild kde a few
days ago; I was just about to hit the Return key with the above when I
remembered I had the same problem; I "solved" it on the spot by
duplicating the definition in Xmd.h.

confusion regarding .include vs DEPENDS

Greetings,

When reading chapter 10 of the pkgsrc doco, I am confused about including
the buildlink3 file vs having DEPENDS in the makefile.  The doco seems to
indicate a preference to using buildlink3 files, but how do you specify a
minimum version for the dependency that way?  I don't want to force
dependencies to be updated when it's not necessary.

Thanks,
Tim

The buildlink3 file has some lines to specify API and ABI minimum
versions, but if you want to specify another minimum version in a
package, you can use something like:

BUILDLINK_API_DEPENDS.foo+= foo>=2.10

You want to include a dependency's buildlink3.mk files *only* if the 
package links against libraries provided by the dependency.  Otherwise, 
use DEPENDS.

See Juan's reply for how to set the version for a buildlink3.mk file.

So, when is it important to specify a version (with either method) and when
is it not?  I'm not completely sure I understand the distinction between
them (better explanation in the doco would be great), and also am still
unsure if this mistake is what caused the unwanted updating.

That works if you want to say "the version in the buildlink3.mk file
is too small; use this instead".  It doesn't work if you want to say
"the version in the buildlink3 file is unnecessarily large; use this
instead".

It's often the case that pkg X depends on pkg Y, and in reality X could
work with a very old version of Y, but the buildlink3.mk files say that
*anything* that depends on Y has to use a recent version of Y.

My understanding is that the versions in the buildlink3.mk files are
the way they are because of concerns about what happens to people who
install binary packages that they downloaded from somewhere.  However,
if you use pkgsrc the way I do:

	update pkgsrc;
	build and install some stuff;
	wait some days/weeks/months;
	update pkgsrc;
	build and install more stuff;

then you will often have to perform unnecessary updates.

It is also one of the few ways to preserve sanity. We already have
issues with partial updates, allowing even more of that doesn't help.

Re: rtorrent & xmlrpc

Yes, I've tried. The problem is that it requires a newer version of  
"xmlrpc-c"
than the one which is currently in "pkgsrc". I tried updating the  
package
and failed because "xmlrpc-c"'s build system is a mess. It is so broken
that I haven't even managed to get the current version to build under
Mac OS X, see PR pkg/38071.

If somebody sorts out the "xmlrpc-c" package I will add "xmlrpc"  
support to
the "rtorrent" package.

	Kind regards
