Hi,

We've run into some strange problems getting the latest wacom drivers
(0.7.4.2 + .3) to work on Fedora Core 4, running kernel 2.6.11 and also
with 2.6.12.

We're using specific software on the system, which requires some
modifications to the src/kernel.spec file for other modules required,
before we recompile the kernel.

Here's the process (example):

$ rpm -ivh kernel-2.6.12-1.1456_FC4.src.rpm
$ rpmbuild -bp --target=i686 /usr/src/redhat/SPECS/kernel-2.6.spec 
$ vi /usr/src/redhat/SOURCES/kernel-2.6.12-i686-smp.config

Because we're using an SMP kernel, this is where we set the
CONFIG_USB_HID=y parameter to CONFIG_USB_HID=m in the kernel-2.6.spec,
WACOM_USB_HID=m is left as default.

$ cd /usr/src
$ ln -s redhat/BUILD/kernel-2.6.12/linux-2.6.12 linux

$ cd /var/tmp ; tar -xvf linuxwacom-0.7.4-2.tar
$ cd linuxwacom-0.7.4-2
$ cp src/2.6.11/wacom.c /usr/src/linux/drivers/usb/input/
$ cp src/2.6.11/hid-core.c /usr/src/linux/drivers/usb/input/

$ rpmbuild -bb --target=i686 /usr/src/redhat/SPECS/kernel-2.6.spec 
$ rpmbuild -bs --target=i686 /usr/src/redhat/SPECS/kernel-2.6.spec

$ rpm -ivh
/usr/src/redhat/RPMS/i686/kernel-smp-2.6.12-1.1456_FC4.newkernel.i686.rpm
$ rpm -ivh
/usr/src/redhat/RPMS/i686/kernel-smp-devel-2.6.12-1.1456_FC4.newkernel.i686.rpm

$ reboot 

$ yum install tcl
$ yum install tk
$ yum install tcl-devel
$ yum install tk-devel
$ yum install xorg-x11-sdk
 
$ cd /usr/tmp/linuxwacom-0.7.4-2

$ ./configure
--with-kernel=/usr/src/redhat/BUILD/kernel-2.6.12/linux-2.6.12/
 --enable-hid --enable-wacom --with-xlib=/usr/X11R6/lib/
 --with-xorg-sdk=/usr/X11R6/lib/Server

$ make

!!! Here we get the following warning !!!

" ... Building linuxwacom drivers for 2.6 kernel.
***Note: Drivers not enabled as modules in your kernel
config but requested 
through configure are NOT built ... "

Even though both CONFIG_USB_HID and WACOM_USB_HID are both set to =m

modprobe seems to recognize the modules, and is able to unload them,
but the make script claims they're not there!  At least, as far as I
understand it.  Either way, the driver isn't installed, and "more
/proc/bus/usb/devices" doesn't show the wacom driver loaded.  But make
doesn't let me get anywhere further...


So why not follow the instructions in the mini-how-to on the linuxwacom
website?  Because following these leaves me with a new UP kernel named
...-prep, which is utterly useless for an SMP machine.

Any ideas?  Thanks,

-jan.
