What is causing "No rule to make target `modules'. Stop"?

[XEyedBear]

I submitted this problem to this forum earlier last week but it elicited no response in a forum environment where reaction to forum posts is outstandingly quick. I guess it was perhaps the thread Title which was off-putting as well as misleading, so I am submitting the problem again (please!) with a more relevant title.

I am trying to compile and install the driver which supports older Philips Web Cam (which my Logitech Quick Cam 3000 Pro needs). I am following the instructions that are part of the PWC package from Luc Saillard. The 'make' step fails and I cannot understand why this script is accessing the directories that it is.

I believe the kernel source is in /lib/modules/2.6.27.23-0.1-pae

But the make script seems to be accessing /usr/src/linux-2.6.27.23-0.1-obj/i386/pae which contains only the file Module.symvers (which I am guessing contains the headers for the kernel source ?)

The output from make says:

make -C /lib/modules/2.6.27.23-0.1-pae/build SUBDIRS=/home/tony/install_temp/pwc-10.0.11 modules
make[1]: Entering directory `/usr/src/linux-2.6.27.23-0.1-obj/i386/pae'
make[1]: *** No rule to make target `modules'. Stop.
make[1]: Leaving directory `/usr/src/linux-2.6.27.23-0.1-obj/i386/pae'
make: *** [all] Error 2


Can somebody please advise me what is causing this error to be invoked adn, by implication, what changes to the make script are required?


I have Googled the error message from make and followed the many 'hits' that are presented from this unique error text. None of the advice given fixes the problem. I am unable to progress beyond this point.

No, kernel sources are always in /usr/src. the stuff in /lib/modules/<kernel>/source and /lib/modules/<kernel>/build is just a symlink to /usr/src/linux source directory, besides the actual modules which are also in /lib/modules. If you have installed the kernel source package, then do as follows which may solve the problem

1) login as root on console
2) cp /boot/config-$(uname -r) /usr/src/linux/.config (note the . (point) in .config)
3) cd /usr/src/linux && make prepare && make modules_prepare

and try compiling your module again

I think I need a little more help here because things do not add up.

There is only one file in usr/src/linux... - Module.symvers. Perhaps this means that I have not got the kernel source installed? However Yast tells me that the package kernel-pae is already installed - in lib/modules/2.6.27.23-0.1-pae. This folder contains 2770+ files which do not appear to be symbolic links,, with a total size about 64 MB.

So do I have the source installed or not? If not, which source pacakge should I install?

[microchip8]

kernel-pae is the kernel *itself* and *not* the kernel source. Search for package kernel-source and install it

[XEyedBear]

OK; I found and installed the kernel files, followed your previous instructions (which appeared to work wthout any problem) and then re-invoked the make. The reult is a lengthy collection of erros, which I assume are caused by the developer of the make file making invalid assumptions. My probelm is that I do not understand what is causing this many erros and so do not understand how to fix the problem.

This is the output from 'make':

Hi
Looks like the OP will need to patch the header files,
it's linux/semaphore.h not asm.

@OP, you do realize the pwc module is part of the kernel?

Hi
Also see that the uvc module may be of use?

In response to the two last questions:

1. Re the UVC module: I am lead to believe that this is not relevant to my older web-cam (Logitech Quick Cam Pro 3000), which is supported, I'm told, only by the PWC driver. Is my understanding correct?


2. Re PWC being part of the kernel: no, I was not aware of this and the reading I have done so far, looking at the web-cam sensors that are supported, also lead me to believe that I had to add the PWC driver to the kernel (and hence the mess that I have managed to get myself into thus far). In fact I have not been able to find an applications with which the camera will work (for example AMSN), so I took this as good evidence that there is currently no support for this web-cam in my version of the kernel. Am I mistaken in this belief?

Yes, If I have understood it correctly, your previous post gave me directions on how to do this. I copied your instructions (i.e. didn't retype them) into a terminal session, logged in as root. Both commands seemed to work without error. But I note that the first command you suggested creates a file called .config in usr/src/linux and not a file called .config.h

Is this intended? There is no .config.h file in the usr/src/linux directory, so I do not understand how the 'make' process can work
