Compat-wireless editing/compiling *** plz help ***

[seza]

Hi,
I have a RASPI equiped with Alfa USB Adptr AWUS036NH and loaded with Arch ver:
$this->bbcode_second_pass_code('', 'Uname -a
Linux alarmpi 3.2.27+ #307 PREEMPT Mon Nov 26 23:22:29 GMT 2012 armv6l ')
Following various tut's I am trying to edit the compat driver to remove the TX power limit
(I am aware of the legal issues related to this - its only a temporary setup for educational purposes)

I attempted different versions of the driver but it always fail when I run 'make'

any ideas please - am struggling here.

thanks

I haven't had any success building it a while ago as well. AFAIK linux-headers doesn't have some necessary headers to build it, but when i copied the necessery files it still errored out. What is the kernel and the error that you get?

All sorts of compilations errors,
mostly missing files - now I've given up on that.
am trying to to use aircrack-ng to see if that helps with using 'iw reg set BO'

cheers

OK, it does build
You have to edit PKGBUILD
First I think you need matching source to you kernel version
http://wireless.kernel.org/en/users/Download/stable/#compat-wireless_3.2_stable_releases

I had to add these
CFLAGS=""
CXXFLAGS=""
it complained that hard and soft float both set, where it gets soft from I don't know

Next, and I don't like this, had to remove this line to stop compile errors
-Werror-implicit-function-declaration
from /root/crrpi/usr/src/linux-3.2.27-16-ARCH+/Makefile
And this is going to need a 1Gb swap file to build

Plus other changes to PKGBUILD

Plus more changes needed in package section
Here is my PKGBUILD so far, let someone else have a go, it builds but doesn't package
Even though I'm in a rpi rootfs chroot, it's seeing the kernel version of the system I'm building on
