Building the madwifi driver with kernel 2.6.20

dracolich · 02-07-2007, 04:23 PM

I've had my Netgear WG511U (AR5212) since the days of kernel 2.6.17. I've been using the madwifi-old driver, latest being r1417, because I've never been able to compile the other. I've tried 0.9.1, 0.9.2 and now 0.9.2.1. I've double and triple checked the required kernel options with my config and everything checks. Now, with kernel 2.6.20, I can't build either. When configuring my kernel I imported the config from my previous 2.6.19.2 and reviewed the menuconfig to make sure everything is ok.

This is the output from make when trying madwifi-0.9.2.1

Code:

And this is make from madwifi-old-r1417-20060128 that has worked until now

Code:

Any help is appreciated.

"I've double and triple checked the required kernel options with my config and everything checks. Now, with kernel 2.6.20, I can't build either."

As I've posted in the past, they're changing the workqueue interface in 2.6.20, and at the very least, it breaks madwifi. I've read somewhere that there is or may be a porting effort going on, but I have no idea what the status is.

Hey all. They say 0.9.3 should work when it comes, which should be any time now. I've tried the current svn as of a few minutes ago, it compiles fine but the module doesn't load. According to somebody on the mailing list it works if you compile it builtin as opposed to a module, but I haven't tried that.

SVN does work, just make && make install as usual

Sorry for not replying sooner. I've been on spring break away from wireless access. Now I'm back and using my card with the SVN driver. Thanks for the tips.
