[Libusb-devel] OpenUSB 1.1.0 and svn failed to be built under Ubuntu 9.10

[Xiaofan C. <xia...@gm...>]

There must be something wrong with the auto-tools that it generates a
problematic configure file (same for the configure files in the release
package 1.1.0 (extra "else" in line 24720 for configure file in 1.1.0).

It will generate the following error (both the svn version and 1.1.0).

//////////////////////////////
checking for GLIB... configure: error: in
`/home/mcuee/Desktop/build/openusb/libopenusb-1.1.0':
configure: error: The pkg-config script could not be found or is too
old.  Make sure it
is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.

Alternatively, you may set the environment variables GLIB_CFLAGS
and GLIB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

To get pkg-config, see <http://pkg-config.freedesktop.org/>.
See `config.log' for more details.

Removing the extra line will help. But then the generated Makefile
has not got the following critical flags. So I have to modify the
Makefile manually by copying the flags generated by 1.0.2.

DBUSGLIB_CFLAGS = -I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include
-I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
DBUSGLIB_LIBS = -L/lib -ldbus-glib-1 -ldbus-1 -lpthread -lrt
-lgobject-2.0 -lglib-2.0
DBUS_CFLAGS = -I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include
DBUS_LIBS = -L/lib -ldbus-1 -lpthread -lrt

GLIB_CFLAGS = -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
GLIB_LIBS = -lglib-2.0
GTHREADS_CFLAGS = -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
GTHREADS_LIBS = -pthread -lgthread-2.0 -lrt -lglib-2.0
HAL_CFLAGS = -DDBUS_API_SUBJECT_TO_CHANGE -I/usr/include/hal
-I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include
HAL_LIBS = -L/lib -lhal -ldbus-1 -lpthread -lrt

Moreover, the definitions in emulation.c do not match usb-0.1 so
it has to be changed to get through the building process.
