Problem building gspca module

Problem building gspca module

[Dave Fine]

I'm trying to build the gspca module and insmod into my current
running system. I can compile the module, but can't insmod it.

steps I take to build:

$ cd /usr/src/linux-source-2.6.38
$ sudo cp /boot/config-2.6.38-8-generic .config
$ sudo make oldconfig
$ sudo make prepare
$ sudo make modules_prepare
$ sudo make scripts
$ sudo make SUBDIRS=drivers/media/video/gspca
$ cd drivers/media/video/gspca
$ sudo insmod gspca_main.ko
$ insmod: error inserting 'gspca_main.ko': -1 Invalid module format
$ dmesg | tail
[995219.523934] gspca_main: no symbol version for module_layout


when compiling the module, I get the following warning, which I feel
is related to problem of not being able to insmod it, but don't know
how to fix it:

  WARNING: Symbol version dump /usr/src/linux-source-2.6.38/Module.symvers
           is missing; modules will have no dependencies and modversions.


Does anyone know what I'm doing wrong?

Thanks,
Dave

Hi Dave,

You must either
- generate a full kernel,
- or build the video stuff from a linuxtv git repository,
- or get and build the last gspca tarball from my web site.

In the two last cases, the linux headers of your kernel must
be installed (in Debian, these are splitted into three packages
'linux-headers-2.6.38-..' and 'linux-kbuild-2.6.38').
