Can't compile the driver!

[gres]

I am trying to compile the driver for web cam Logitech 4000 pro. I have installed kernel-headers and kernel-devel i686 & i86_64 and lots of another development software. I used this link to install proper soft
http://forums.fedoraforum.org/forum/...cc+compilation
But the compilation doesn't work. It worked well on FC5_64! What's wrong with FC6?

The error message is below:

Your driver needs revision. Drivers aren't supposed to use linux.config.h - it's been deprecated for some time and recently removed. Some of the syntax erorr are due to use of the GCC4.1.x compiler which does tighter checking.

You could reduce the error/warning count by using the lagacy compiler (from the rpm repo) but you'll still have a little work to do.

BTW it appears to me that a pwc-if driver is included in the 2.6.19 kernel source. It should be trivial to rebuild a kernel with pwc-if enabled (it's not enabled in the FC releases, but it is in the FCn kernel sources).

[[[edit]]]
Oops - mybad.

The module already appears in the modules tree.
/lib/modules/2.6.19-1.2911.fc6/kernel/drivers/media/video/pwc/pwc.ko
/lib/modules/2.6.19-1.2911.6.4.fc6/kernel/drivers/media/video/pwc/pwc.ko

Not certain, but see if this is the driver module you want.
Try "modprobe pwc" and see what happens.
---
driver for the pwc.ko that comes with your kernel is self-described as
webcams:
* Philips PCA645, PCA646
* Philips PCVC675, PCVC680, PCVC690
* Philips PCVC720/40, PCVC730, PCVC740, PCVC750
* Philips SPC900NC
* Askey VC010
* Logitech QuickCam Pro 3000, 4000, 'Zoom', 'Notebook Pro'
and 'Orbit'/'Sphere'
* Samsung MPC-C10, MPC-C30
* Creative Webcam 5, Pro Ex
* SOTEC Afina Eye
* Visionite VCS-UC300, VCS-UM100

The PCA635, PCVC665 and PCVC720/20 are not supported by this driver
and never will be, but the 665 and 720/20 are supported by other
drivers.

Some newer logitech webcams are not handled by this driver but by the
Usb Video Class driver (linux-uvc).

The built-in microphone is enabled by selecting USB Audio support.

FATAL: Error inserting pwc (/lib/modules/2.6.19-1.2911.6.5.fc6/kernel/drivers/media/video/pwc/pwc.ko): Unknown symbol in module, or unknown parameter (see dmesg)

What does that means?

Same problem with Logitech 4000 and have been trying to get it right for quite a while. Running FC6 and kernel latest but how do I get the kernel source as I need it to get it right. Been looking but can't find how I can get source files for kernel and as a relative newbie, I assumed they would be installed with the kernel?

Hello:
Normally all you require is the matching kernel-devel and kernel-headers rpms(s)
yum install kernel-devel kernel-headers
then you should be good to go

Here's what I get when I try to c ompile the module. Thanks Seve, I installed kernel devel and headers as you directed. I tried same as root, same result.

In /lib/modules, I see three directories: 2.6.10-1.727_FC3, 2.6.19-1.2911.6.5.fc6, 2.6.19-1.2911.fc6 Each directory has similar content. In the two newest, the "build" and "Source" are flashing red.

I have deleted the old fc3 directory. Should I delete the older directory from the two remaining and then do a "make" to compile the module?

Well forget all the foregoing. I downloaded the latest test Fedora and it recognizes my Logitech Pro 4000 and driver pwc. But in Kopete, I can't get a picture and I can't send and receive video from other webcams. By the way, in downloaded the new test FC6 preceding what will be FC7, when booted it told me I had 254 program updates. DL failed as there were errors, however, when I downloaded and installed a new kernel from the list, I was able to download and install ALL the updates with no problem - for all those who await Fedora 7!!
So now that pwc is recognized, I still get no picture.
