autoconf.h

[upc0d3]

Hi,
I'm trying to make my wireless driver.
It's the I'm getting the driver from: http://www.broadcom.com/docs/linux_s...0_82_38.tar.gz

Well, my problem happens when I'm do the "make" to build the driver.

The error is that "autoconf.h" was not found.

I've already install the linux source and headers.

What else do I need ?!

Hi, the correct way to get Broadcom drivers to work on BT5 is the following:

1. Download the Broadcom drivers: http://www.broadcom.com/support/802.11/linux_sta.php
2. Unpack and modify the ‘src/wl/sys/wl_linux.c‘:
Line 35 (after #include <linux/etherdevice.h>) add:

#include < linux/sched.h >

3. Compile the code with: make
4. Copy the new driver: sudo mv wl.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless
5. Update dependencies: sudo depmod -a
6. Modify the blacklist to include the ‘b43′ and ’ssb’ drivers /etc/modprobe.d/blacklist.conf (Add below the bcm43xx blacklist)

The part above you probably have seen a few times while googling for the answer. But there is a small problem, as you would have noticed, the ‘ssb‘ driver cannot be blacklisted. It is included in the initrd as I remember from the ubuntuforums. To solve this issue modify the /etc/rc.local to include before the exit(0):

Code:

rmmod ssb
modprobe wl

Now on startup the ssb gets removed and after that the new wl gets inserted. Adding wl to the /etc/modules will not help because the removing needs to be done first.
So with the /etc/rc.local modification everything happens in the correct order for perfect WiFi.

This was tested multiple times on a MacBook Pro with the Broadcom 4328 chipset and should work for all chipsets not supported by the b43 drivers.

Update:
Not all systems include the 'linux/sched.h' file. Install the 'linux-headers-generic' package if you get errors. The generic package is a meta package that should install the propper package for your kernel. If it isn't working install with
Code:

sudo apt-get install linux-headers-$(uname -r)

Good Luck

Didn't work:

And I've installed the headers:

Well, If anyone knows anything about this, I appreciate the help.

Make worked for me after changing line 485 in src/wl/sys/wl_linux.c from

init_MUTEX(&wl->sem);

to

sema_init(&wl->sem, 1);

I found this solution at: http://bugs.gentoo.org/350196

Hi @Astrobyte,

I've done what did you say. But didn't work, look:

Output when I load the module: ( #insmod wl.ko )

# tail -f /var/log/messages

I didn't see an error in that. Moving on:

As you can see, the wireless interface seems work, but the light of my wireless remains red, which means the wireless didn't actually turn on.

I've had unload b43, ssb and the wl that came with the distribution.

I'm doing something wrong ? or what ?

Thanks for the help.
