Hi,

Running Slack 12, I've been trying to compile a kerneldriver for the
ACX100 Wificard. According to the sf.net page for ACX, this should be
possible despite ACX not being a kerneloption. I've installed and
compiled 3 times now according to their directions (create
drivers/net/wireless/acx, untar into drivers/net/wireless/acx, make
menuconfig, make && make modules_install) but it doesn't deliver the acx.ko
Now I want to create the acx.ko myself, but how should I do that? I've
tried to find it on the net, but found no clear directions.

Thank you.

Did you remember to make the modification to the Makefile in the
directory above the one you made for acx, as they describe in their HOWTO?

Just as a refresher, the modification is:

echo 'obj-m += acx/' >> Makefile

They have a description of how to build the module outside of the kernel
tree in their HOWTO, did you try that?

Does/did anything in the acx directory compile? Any object files (*.o)
in there after the make?

Yes, I did.

Will try.

Nothing compiled so far, but will try the 'outside' version.

That's very strange. Does the compiler exit with an error message? If
it can't even create one object file you'd think it would
have the courtesy to cough up an error message...

Yes, it ends with an error message, but I haven't written it down.
Before trying the 'outside' version, I'll recompile and give it. Given
time, will do so tomorrow.

As promised the error:

Will try outside-kernel compilation now.

No /usr/bin/cmp? It's part of the diffutil packages, what do you get
from `ls /var/log/packages/diffutil*'

Likely to get the same thing if the the diffutils package isn't
installed though...

OK, installed the diffutils package. make && make modules_config (inside
kernel) didnt give the acx.ko. So I did the outside version. This
compiling ends with this:

Well then I think the obvious question becomes, IS there a file
/usr/src/acx-20080210/acx/Makefile ??

I just tried building it myself and got:

$ make -C /lib/modules/`uname -r`/build M=`pwd`
make: Entering directory `/usr/src/linux-2.6.22.6'

Ok, this is my directory listing:

Looks to me like Makefile actually is there. But this line looks odd to me:

scripts/Makefile.build:17: /usr/src/acx-20080210/acx/Makefile: No such
file or directory

There is a directory "script", not "scripts". Any clue about that?
