Can't compile a driver without header files present?

Background info

I'm working with a GuruPlug...maybe you've heard of them.

I'm trying to get EasyCap DC60 drivers installed on it
(easycap_dc60.0.9.tar.gz), but in the README file I see that the "header files" must be present.

Unfortunately they are not. This little wall wart runs Debian/Lenny, probably some server oriented build.

uname -r reports:

2.6.32-00007-g56678ec

It boots to RunLevel 2 and stays there, incidentally.

I tried apt-get install linux-headers-$(uname -r) but I am told "file not found" or something similar.

Does anyone have ideas about how to proceed?

Kernel headers should be in /usr/include/linux, mainly.
Have you includes? can't you copy them in?

The GuruPlug only has 500 Mb of flash nand for a "hard drive"
the debian/lenny distro is "horribly foreshortened" and I don't
have any access to "includes".

My head is spinning with all the advice I've seen on the net about
"cross compiling" on a different machine and copying the driver files
manually to the GuruPlug.

I DOESN'T HELP ONE BIT that Xmarks keeps eating all my bookmarks in Firefox either.

If you can grab/find some kernel source (2.6.32.x or near it) and cd into the top source dir, there are 2 commands
make headers_check
make headers_install

One of which installs a set of headers. The worrying thing is, though, that you compile with 3 tools
1. gcc
2. glibc (libraries & includes)
3. kernel headers

Now if you haven't got headers, they didn't set your distro up to compile, so I'd wonder about the other 2. Check
ls -l /usr/bin/cc

Hi,

Maybe this will help: Building ARM GNU Cross compiler …

Compiling Linux Kernel for the Plug Computer - PlugWiki especially: 2 Crosscompiling the kernel

I'm giving up on Google; duckduckgo

BTW, builds for ARM are done all the time. Why depend on the plug to do the compile when you can build on a faster system with more resource(s)?

Thanks for all this good info. I'm amazed not only how much there is to learn,
but that Linux/Ubuntu makes all this functionality available.

This is how I usually learn...I have a goal in mind and I learn what I need
to achieve it--asking questions along the way of course.

Thanks again for sharing your expertise with me.
