I just upgraded the FreeBSD buildbot machine from 6.4 to 8.0, and I
ran across some interesting differences.
The libusb API that we use (0.1) is available in /usr/include/usb.h
and /usr/lib/libusb.* as before, but it seems to be the compatibility
layer from libusb 1.0.
However, it doesn't include the libusb-config binary.
This is from the 'ports' Makefile for NUT:
########## - - 8< - - cut here - - ##############
.if !defined(WITHOUT_USB)
. if ${OSVERSION} < 800069
LIB_DEPENDS+= usb-0.1.8:${PORTSDIR}/devel/libusb
. else
EXTRA_PATCHES= ${FILESDIR}/extra-patch-m4_nut_check_libusb.m4
. endif
CONFIGURE_ARGS+= --with-usb=auto
MAN8+= bcmxcp_usb.8 megatec_usb.8 richcomm_usb.8 tripplite_usb.8 \
usbhid-ups.8
PLIST_SUB+= NUT_USB=""
.else
CONFIGURE_ARGS+= --without-usb
PLIST_SUB+= NUT_USB="@comment "
.endif
########## - - 8< - - cut here - - ##############
The full text of the m4 patch is here:
http://www.freebsd.org/cgi/cvsweb.cgi/ports/sysutils/nut/files/extra-patch-m4_nut_check_libusb.m4?rev=1.1;content-type=text%2Fx-cvsweb-markup
But the gist of it is that they just hardcode "" and "-lusb"
for
$CFLAGS and $LDFLAGS, respectively.
For many FreeBSD 8.0 users, this will be a non-issue, since they can
just run 'make install' in the ports directory. However, given all of
the USB stack changes, I suspect we might have to ask some users to
test against a SVN version of NUT, so it might be nice to enable USB
support out-of-the-box.
Suggestions?
Arjen: if you don't have much free time, I can do some local testing
here, but I am not sure which of the autoconf library search routines
I should use as a model.

But I really feel that this is a regression in FreeBSD and that not including libusb-config is really hurting. I fail to understand why the FreeBSD maintainers choose this is easier to fix in all packages that use libusb, than to just include a 'libusb-config' that simply returns these values.> Arjen: if you don't have much free time, I can do some local testing > here, but I am not sure which of the autoconf library search routines > I should use as a model.I've submitted something. Once you get the hang of it, the autoconf tools are remarkably easy to use. Best regards, Arjen -- Please keep list traffic on the list
