Installation instructions

This post describes gumstix uvc driver installation for a Logitech QuickCam? Pro 9000. It follows this wiki page as a guideline.
It requires that the steps in this wiki have been performed.
Firstly check-out the old driver sources from:


svn co svn://svn.berlios.de/linux-uvc/linux-uvc/trunk

After file checkout, one should change the Makefile.
Change the KERNEL_DIR var to point to your gumstix kernel path, as in:

KERNEL_DIR :=
/home/developer/gumstix/gumstix-oe/tmp/work/gumstix-custom-verdex-angstrom-linux-gnueabi/gumstix-kernel-2.6.21-r1/linux-2.6.21/

Define the CROSS_COMPILE var:

CROSS_COMPILE := /home/developer/gumstix/gumstix-oe/tmp/cross/bin/arm-angstrom-linux-gnueabi-

Change make lines so that they include your CROSS_COMPILE and ARCH=arm vars:
From:
@(make -C $(KERNEL_DIR) M=$(PWD) CROSS_COMPILE=$(CROSS_COMPILE) modules)

to:

@(make -C $(KERNEL_DIR) M=$(PWD) ARCH=arm CROSS_COMPILE=$(CROSS_COMPILE) modules)

And from:
@(make -C $(KERNEL_DIR) M=$(PWD) INSTALL_MOD_DIR=$(INSTALL_MOD_DIR) INSTALL_MOD_PATH=$(INSTALL_MOD_PATH) modules_install)
to:
@(make -C $(KERNEL_DIR) M=$(PWD) ARCH=arm
INSTALL_MOD_DIR=$(INSTALL_MOD_DIR) INSTALL_MOD_PATH=$(INSTALL_MOD_PATH)
modules_install)

Now, type make uvcvideo
The file uvcvideo.ko is built. This file should be copied to /lib/modules/2.6.21/kernel/drivers/media/video/uvcvideo.ko

Nevertheless, if you type make, you'll notice a message like:

---

The USB Video Class driver has moved to http://linuxtv.org/.
Using the Berlios SVN repository is now deprecated.
Please check http://linux-uvc.berlios.de/ for download instructions.
If you really want to compile this historical version, run 'make uvcvideo'.

---

which tells us that we are using deprecated files for the driver.
I've tried to use the latest drivers from the Mercurial clone repository, but I'm getting this error:

"/home/developer/uvc-new/uvcvideo-90c7dc24fb4d/v4l/cx18-driver.h:65:4: error: #error "This driver requires kernel PCI support." "

In order to build it, I've changed the root Makefile to:

CROSS_COMPILE := /home/developer/gumstix/gumstix-oe/tmp/cross/bin/arm-angstrom-linux-gnueabi-

install:
$(MAKE) -C $(BUILD_DIR) ARCH=arm CROSS_COMPILE=$(CROSS_COMPILE) install

%::
$(MAKE) -C $(BUILD_DIR) ARCH=arm CROSS_COMPILE=$(CROSS_COMPILE) $(MAKECMDGOALS)

And the v4l/Makefile to:

OUTDIR ?= /home/developer/gumstix/gumstix-oe/tmp/work/gumstix-custom-verdex-angstrom-linux-gnueabi/gumstix-kernel-2.6.21-r1/image/lib/modules/2.6.21/build
SRCDIR ?= /home/developer/gumstix/gumstix-oe/tmp/work/gumstix-custom-verdex-angstrom-linux-gnueabi/gumstix-kernel-2.6.21-r1/image/lib/modules/2.6.21/source

I've tried to issue some "make -i" command, but I doubt it will work. If you've made any progress with the new drivers, feel free to comment.
The old drivers have worked pretty fine as well.
