compat-wireless can't compile under kernel 3.2.0 both 3.3-rc1-2 and 2012-01-26 - error: missing binary operator before token "("

Hi,

I'm facing a bug you fixed in compat-wireless-3.3-rc1-2: rt2800pci:
fix spurious interrupts generation
But I must run a 3.2.0 kernel with some patches for my display driver
(cause I'm greedy and I want both to see the screen and access
internet)

I tested in kernel 3.0.0 and I can compile and see the bug is fixed.

but when I try to compile under 3.2.0 I get the following error:

$ make
./scripts/gen-compat-autoconf.sh config.mk > include/linux/compat_autoconf.h

Re: compat-wireless can't compile under kernel 3.2.0 both 3.3-rc1-2 and 2012-01-26 - error: missing binary operator before token "("

Luis needs to apply "compat: use kconfig.h in compat-2.6.h for 3.1
and later kernels" that I posted earlier.

Hi John,

thank you.

sorry for jumping the gun, but I've been fighting various driver
problems for weeks and now I feel so close...

I tried to apply your patch and I imagine I did right since the error changed...

I created a text file patch.txt and then from the folder of
compat-wireless I did:
patch -p1 < patch.txt
patching file include/linux/compat-2.6.h (output)

Hi Rick,

Yes, I think so. But I tried again with make clean to be sure and I
get the same (new) error.

thank you,

Regarding carl9170 wifi linux driver

Hi,

We are planning to use the below wifi dongle as station and AP.

https://www.thinkpenguin.com/gnu-linux/penguin-wireless-n-usb-adapter

We got the linux driver from the below path

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-testing.git

We found the driver source in drivers/net/wireless/ath/carl9170.

Our Question:

Is the carl9170 driver present in the above folder is a complete open
source driver?

Or is it not complete driver and is there any NON-GPL code that is not
provided as an open source?

Please clarify it. Your immediate response would be really appreciated.

Also it would be great if there is any design document or programmer’s
document for the above mentioned Wifi dongle chipset available.

Regards,

Prashant

You need to change the mac address of the second device once you create it.

Apologies for the delay, and thanks a lot, applied and pushed!
