WLAN newbie question (Airport cards, ndiswrapper, etc.)

**JoeyJoeJoe** · 11-27-2006, 01:45 AM

I think I know part of why it the AirPort2 driver did not work. lspci reports the following Ethernet controllers

01:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 22)
02:00.0 Ethernet controller: Atheros Communications, Inc. Unknown device 001c (rev 01)

The Marvell is my wired NIC, the Atheros my wireless so mine is an AirPort card that is not Broadcom (??). After a bit of digging around I came across http://madwifi.org/ and pulled down madwifi.0.9.2.

It took me a while to figure out where the kernel source files were. Once I found them, I ran make with the KERNELPATH indicated and go the following error:

[root@localhost madwifi-0.9.2]# make KERNELPATH=/usr/src/kernels/2.6.18-1.2849.fc6-i686
/bin/sh: cc: command not found
Checking requirements... ok.
Checking kernel configuration... FAILED
Only kernel versions 2.4.x and above are supported.
You have .
make: *** [configcheck] Error 1

Anyone had luck with madwifi?

Checking kernel configuration... FAILED

You need the appropriate configuration file, your current kernel was build with, located in /usr/src/kernels/2.6.18-1.2849.fc6-i686 and named .config (remember startign with a dot) I dont know how FC does it, but some distribs places it as /boot/config-version

/bin/sh: cc: command not found

This however seems to be a more severe issue... Since you need the right develop tools in order to compile madwifi.

Here's the reply I got back from the mad-wifi mailing list. Sorry to crosspost it here, but I they were less informative and helpful due to my "noobishness"

The build system would probably do it much faster.

Generally, you shouldn't need to override anything unless the build
system fails to find the necessary parameters automatically. The
INSTALL file suggest running "make" without arguments before it
discusses how to specify the path to the kernel sources.

cc is "C compiler". Apparently you don't have one, or it's not called
cc. In the former case, installe the compiler. In the later case, try
specifying the compiler on the command line, e.g.

make CC=gcc34

if gcc34 is your compiler. Note following requirement from INSTALL:

- gcc of same version that was used to compile the kernel (ignoring this
will cause "Invalid module format" errors during module load).

To find out the compile version used for the kernel, run dmesg to see
the kernel messages. It can also be saved in /var/log/dmesg.

It's a shame the error message wasn't not helpful at all. I have fixed
the build system to provide more helpful output if the compiler is
broken or missing.

For starters, I need to know where my C compiler resides in FC6. I thought I pulled down the development tools and the compiler would be included in that, no?

Where did you mail it to? I don't remember seeing it on the develop list, naturaly I'm not subscribing to the users maillinglist..

Here are a few hints:

> cat /proc/version

look for GCC version <some version> to see if you have it installed run

> gcc --version

Else look for /usr/bin/gcc or something similar... It usualy comes with the gcc package, other packages required would be cpp and libc-dev

By the way, I'm usualy to find in #madwifi on irc.freenode.net if you're in need of emidiate consultance.

//edit
I just remembered a few other packages which could be useful these are make, kernel-kbuild and kernel-package.

Hi redhead.

FYI I am subscribed to the Madwifi-users@lists.sourceforge.net mailing list

My gcc version is
[Joe@localhost ~]$ gcc --version

gcc (GCC) 4.1.1 20061011 (Red Hat 4.1.1-30)
Copyright (C) 2006 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO

I ran pirut and downloaded the following packages which had not been
installed:

gcc - 4.1.1-30.I386
gcc-c++ - 4.1.1-30.I386
libgcc - 4.1.1-30.I386
libgcj - 4.1.1-30.I386
libgomp - 4.1.1-30.I386
libstdc++ - 4.1.1-30.I386

Now I got a little further, but still errors:

I will look for and download the other packages you mentioned.

Thanks,
