compat-wireless 2.6.35_rc2 build errors

compat-wireless 2.6.35_rc2 build errors

[Richard Farina]

I realize we are still pretty early in the rc process but there are some 
seemingly significant problems building compat-wireless 2.6.35_rc2 
(which should be very close if not identical to the linus tree). I have 
copied the rt2x00 team because of the first error and Luiz for the second.

First and foremost this won't build at all:

Error 1


Additionally but likely less important this driver seems to be defining 
variables overriding kernel headers, I can't imagine that is good.  Not 
sure if this is something that the driver needs to fix or needs to be 
fixed in compat-wireless but here it is:

I'll try to build the rc2 kernel and see if these errors are the same.

After talking to Hauke2 on irc it seems that this outcome is very 
expected when you try to build a mips driver for x86_64.  I shouldn't be 
trying to build this at all.  Compat-wireless has a bunch of ifneq 
statements which seem to be how this type of stupidity is prevented, 
however, I can't exactly grok how to make this work.  I know this driver 
should dep RALINK_RT288X || RALINK_RT305X but I can't figure out how to 
modify the section of config.mk to do that properly:

ifneq ($(CONFIG_CRC_CCITT),)
CONFIG_RT2800PCI=m
CONFIG_RT2800PCI_PCI=y
CONFIG_RT2800PCI_RT30XX=y
CONFIG_RT2800PCI_RT35XX=y
# CONFIG_RT2800PCI_SOC=y
endif
NEED_RT2X00=y

Currently it is just commented out which allows me to build but really 
it should be uncommented and have a proper check to see if it should be 
built or not. Luiz can you do this? Or someone hint me on how in the 
world I would do it? I'd spend more time trying to figure this out but 
the grass isn't going to cut itself.

Thanks,
Rick Farina
