Subject: [Bluez-users] turning OFF dbus and other extras support?

It appears that the autoconf process is a little wonky at the present. Are
these known issues?

Specifically, autoconf doesn't seem to listen to the negative-versions of
--enable (i.e. disable support), and the pkg-config output is taken as
gospel.

I can't disable fuse support with --enable-fuse=no or --disable-fuse (nor
cups, haven't tried others). I'm running Slackware 10.2 which does have
pkg-config, and which does respond correctly. I did not install bluez-libs
as a package, but it *is* installed; the environment variable overrides are
not heeded, so I have to mangle the Makefile or configure script manually to
get the thing to compile.

I was also hoping that you'd hear my plea for the ability to make dbus support
*optional* -- I'm using bluez in an embedded system and have to thus stick
with an older (and non-supported) version. dbus support adds a LOT of
additional requirements, including XML, and that's a significant addition to
any small system.

you might wanna try to set PKG_CONFIG_PATH to make it find the needed
bluez.pc file. Check "man pkg-config" for more details.

If these libraries are not found, none of them get build. You might see
make entering these subdirectories, but that's it.

It is more than simple notification thingy. You can control all needed
functionality. And this is why it is 3.x now and no longer 2.x.

Then go with expat. It is small and lightweight.

Nobody said, that it is easy, but even the Nokia 770 for example is
happy with D-Bus and I know that a lot of embedded people actually use
D-Bus instead inventing a message bus over and over.

Seems like a weak way to check for a library, but I imagine that only the
slackware and slackware-derived distros would have this particular issue:

checking pkg-config is at least version 0.9.0... yes
checking for BLUEZ... Package bluez was not found in the pkg-config search
path.
Perhaps you should add the directory containing `bluez.pc'
to the PKG_CONFIG_PATH environment variable
No package 'bluez' found
configure: error: Bluetooth library is required

$ BLUEZ_CFLAGS=-I~/files/bluez-libs-3.2/include
BLUEZ_LIBS="-L~/files/bluez-libs/src/.libs -lbluetooth" ./configure

This lets it work, so there's a viable workaround for us old coots. :-)

No, I was mistaken here. I reran the configuration with the command line
above and pkg-config told the configure script that fuse, openobex and libusb
weren't found, but let it build regardless.

A complete separate protocol to do what? v2.25 seems to get by fine without a
notification subsystem.

Regarding dbus and an xml requirement -- the dbus wiki page seems to disagree
with you on this. From http://www.freedesktop.org/wiki/Software/dbus:

"D-Bus' only *required* dependency is an XML parser (either libxml or expat)."

I will make another attempt at building dbus and bluez-3.2 under my embedded
environment. I may have been overly impatient in trying to get it to work.

the pkg-config part only sets *_found and you need *_enable to actually
activate an optional feature.

You should have. The sample calls for configure can be found in the
README and I simply don't see any problem at the moment. I need some
more input here.

I am not going to change this back. Otherwise we would have needed a
complete separate protocol and this would have bloated the Bluetooth
code. And the requirement of XML is a myth. It brings its own XML parser
with it.
