I tried to install madwifi, so I could get my TEW-441PC working, but when I went to make, this is the error I got:

/bin/sh: line 0: cd: /lib/modules/2.6.18-5-486/build: No such file or directory
Makefile.inc:66: *** /lib/modules/2.6.18-5-486/build is missing, please set KERNELPATH. Stop.

I echoed kernelpath, and it wasn't set to anything! I tried to figure out what to set it to, but I can't figure out how to find "build".

So instead I went and tried to install ndiswrapper after that, but when I tried to make that, it gave a gazillion errors, but basically acted like it didn't understand basic C commands. Some examples are:

loadndisdriver.c:527: warning: implicit declaration of function ‘atoi’
loadndisdriver.c:542: warning: implicit declaration of function ‘atof’
loadndisdriver.c:549: warning: implicit declaration of function ‘strcmp’

I know that I have gcc 4.1 installed (I checked with gnome-apt). I'm not even really sure where to start in this problem... Anyone have any ideas for me?

Install the kernel source package for the kernel you're running. You'll probably want the headers as well.

I loaded linux-header, but I couldn't find a linux-source or kernel-source anywhere. I tried downloading linux-image and that changed things, but now when I try to make madwifi, it couldn't find the headers, so it of course gave a bunch of errors like ndiswrapper did. How do I tell it where to find the proper header files? Or did I download the wrong thing?

Looks like something's gone wrong, as you're missing some headers you definitely should have.

So no one knows what might be the problem here? Whatever is going on, I can't seem to install anything except what I use aptitude to get. Is there some path that I need to set? Or a header file or something that I'm missing? This seems like a fairly fundamental problem, so I'm sure that someone else has run across this before...

Those C header files are part of libc6-dev. Do you have it installed?

Norm

Yes, I have "libc6-dev" installed. I also have "libc6" and "libc6-i686" installed. I'm running an Intel dual core processor, so the "i686" should apply to me (I think).

Anything else I could check?

From the gcc docs:
So make sure those C headers reside in one of those directories. On my system they're in /usr/include.

Try running in your madwifi directory and post the results.

Norm

I managed to get it to make properly. I went and installed "linux-headers 2.18-5" rather than "linux-headers 2.18-5-686", and it installed without error.

Now I just have to get it to work... I try to follow the instructions on the madwifi website, and it breaks down when I get to trying to scan. It simply says:

ioctl[unknown???]: No such device
wlanconfig: unable to get scan results

I try to create a ath0 device, (which shouldn't be necessary wit hthe newer build, but I tried anyway) and it said:

wlanconfig: ioctl: No such device

So I went to check what devices are in the system, and all there were was eth0, eth1, and lo. Shouldn't there be a wifi0 or a device like that in the system already? Or is this another patch that I need to install?

If you're running Debian, in the future, you'll find it better to use Module-Assistant to compile and install kernel modules. As root, just type Module-Assistant or m-a. There will be an ncurses-type graphical interface to walk you through installing available kernel modules. You might have to install the package first using apt-get install module-assistant. It's the "Debian Way".

Try an lsmod and see if the ath_pci module is installed. If not, you'll have to install using modprobe ath_pci.

Check the madwifi docs - they are pretty good.

The modprobe ath_pci did put a couple modules on the list when I typed lsmod, but it didn't seem to make a difference. I have tried reading through the madwifi documentation. It's quite extensive, but I can't find where it address any problems like what I'm seeing here.

Here's what I tried; Any more suggestions?

Post the results of lsmod as well as ifconfig.

Does the computer have two different wired Ethernet NICs? There's an eth1 and eth2. Don't see the expected wlan0 or ath0 or something similar.

Is the wifi card a PCI card or what? Try lspci to see what it is reporting.

There is a Wireless networking forum here. You might want to post a question listing the details of your computer, wifi card, and the results of what you've done so far.

I suspect there may be some installation issues with the madwifi module installation.

*nods* Yes, there are 2 ethernet ports built into the motherboard. I'll post a question over on the wireless forum. The lspci says that I have a "unknown device" so you're probably right about it being a installation issue.
