Web cam driver GSPCA trouble compiling

dasy2k1 · 07-13-2009, 01:17 PM

I have a new webcam that gives the following output from lsusb

Code:

Bus 002 Device 007: ID 0c45:600d Microdia TwinkleCam USB camera

a quick google search suggested that the GSPCA kernel module would be appropiate and could be insalled in gspca-source from apt (ubuntu 9.04)

the readme file gives the following instructions to insatll the module

Code:

   m-a prepare
   m-a a-i gspca

the first stage working fine but the secoond command fails with this as the output log

Code:

gspca-source.buildlog.2.6.28-13-generic.1247507635

any ideas what i need to do to get this webcam woriking??

It does not appear to be finding your kernel source in /usr/src/linux-2.6.28-13-generic/asm . You only downloaded the kernel headers.
Compile your kernel. Use the boot/config-<your_kernel>.
Run 'make headers check' if your /usr/src/linux-2.6.28-13-generic/asm directory is empty.
Do not run make clean
Make sure the link in /lib/modules/2.6.28-13-generic/build points to your kernel - not the headers.

Then, try to compile again. If it craps out, usu8ally hitting the uop arrow and return gives the error we need to see

ok lets take this one step at a time....
the closest ive come to building kernels is installing the NVIDIA modules (before apt did it for you) and that only needed the headers,

serched synaptic for the source code for my kernel (i just had headers before)

the closest was linux-source that gave me a tar.bz2 file called linux-source-2.6.28 and was versioned as 2.6.28.13.7 in apt.

unpacking this archive gives me /usr/src/linux-source-2.6.28 which has no ASM directory inside

running /boot/config-2.6.28-13-generic gives me no output at all and just returns me to the prompt

what do i do now?

You can get kernel source from ftp://ftp.xx.kernel org, where 'xx' is your country code. Thge config file is a settings file - it should not run.

On the asm directory. My bad. It's actually include/asm. Change into the linux-2.6.28.7/ directory run these commands

cp /boot/config-2.6.28-13-generic ./.config (fullstops important)
make clean
make

This will run for a while and add about 200 megs of compiled files Grab a coffee. Your new kernel will be 2.6.28.13.7-generic
Now you are on 2.6.28.13. Make sure the /lib/modules/2.6.28.13-generic/build symlink points at your compiled kernel source.

NOW build the module

Ok i have compleated that step....
how do i point the module towards the sources to allow it to build

business_kid · 07-16-2009, 03:59 AM

Your module will get the kernel version by

1 running uname -r
2 Following the /lib/modules/2.6.28.13-generic/build symlink

make sure that when it does, it finds your kernel source. Then just build the module
