Error Installing a Driver

[Jimcando]

I'm trying to install a driver for a Jetway ADPE4S Daughterboard on Ubuntu 10.04 but coming up against some problems.

When I use 'make', I get this error:

make ARCH=x86_64 CC=cc LD=ld CROSS_COMPILE= V= -C /usr/src/linux-source-2.6.32 M=`pwd` modules
make[1]: Entering directory `/usr/src/linux-source-2.6.32'

ERROR: Kernel configuration is invalid.
include/linux/autoconf.h or include/config/auto.conf are missing.
Run 'make oldconfig && make prepare' on kernel src to fix it.

make[1]: *** No rule to make target `code'. Stop.
make[1]: Leaving directory `/usr/src/linux-source-2.6.32'
make: *** [all] Error 2

Any ideas on how to fix this?
Not knowing what to do, I've been playing around with it, and copied the files autoconf.h and auto.conf from a folder '/usr/src/linux-headers-2.6.32-25-generic', but that didn't help, it still says "No rule to make target `code'. Stop."

Thanks for any help.

In a traditional *NIX install admin unpacked kernel sources into /usr/src, configured, built and installed kernel. This left behind sources with header files and Makefile. Adding a new driver was simple, additional module was built against same kernel sources.

Nowadays generic kernels are pre-built and come with distro. Thus you do not have prepared kernel sources and get all those errors.
I'm still using traditional method myself hence cannot tell you how exactly to proceed, installing kernel sources seems like good idea. Maybe they come with Makefile and are ready for your module build.

It's true that my Ubuntu install didn't come with the kernel source. It did have a folder called '/usr/src/linux-headers-2.6.32-25-generic', which didn't work. I then downloaded the source and put in in a folder '/usr/src/linux-source-2.6.32'.

It still doesn't work. Giving me the above error.

Well, the thing here is it has to be exactly the source that was used to build your kernel. I suspect there might be a procedure in Ubuntu to get correct sources.
Digging in Ubuntu docs may help.

[Jimcando]

I don't know if there's any other way, but I'm doing it on the source downloaded using
'apt-get install linux-source' which apparently gets the "Linux kernel source with Ubuntu patches"

[Segfault]

Well, sounds like right thing. Too bad I have no Ubuntu around to check it out, but if you run make prepare on sources as suggested in error message you got ... would it fix it?

[Jimcando]

Sorry, I should have mentioned.

I just deleted and redownloaded the source, just to make sure. I tried running the make command on it and I get this error:

Clearly somethings wrong here :/ I just don't know how to fix it.

How does one normally install a driver such as this for Ubuntu? I've never done it before and would like to actually know what is supposed to happen.

[Segfault]

Look, && will run the second command only if first one didn't error, as you did it make prepare was never run.

Operators

[Jimcando]

Duh, just ran them as sudo separately and it seemed to work

$ sudo make prepare
scripts/kconfig/conf -s arch/x86/Kconfig
CHK include/linux/version.h
UPD include/linux/version.h
CHK include/linux/utsrelease.h
UPD include/linux/utsrelease.h
SYMLINK include/asm -> include/asm-x86
CC kernel/bounds.s
GEN include/linux/bounds.h
CC arch/x86/kernel/asm-offsets.s
GEN include/asm/asm-offsets.h
CALL scripts/checksyscalls.sh

$ sudo make oldconfig
scripts/kconfig/conf -o arch/x86/Kconfig
#
# configuration written to .config
#

Thought I'd tried that before, but it seems to have worked now, yes?

[Segfault]

Will your driver build now?
