Hi,

I've got a WiFi USB key with an antena which i want to use with my efika mx smartbook. The driver is better in compat-wireless than in actual kernel.

when i run make (after ./script/driver select rt2x00), the header file mach/memory.h can't be found. I've searched with find all my disk without sucess.

Help greatly appreciated.

I ran into this as well when trying compat-wireless. I didn't find a solution either. I think that compat-wireless does not work at all with 2.6.31 kernels though for some reason.

Ok, but why the file mach/memory.h is included in the /usr/src/linux-headers-2.6.31.14.20-efikamx/arch/arm/include/asm/memory.h file if mach/memory.h doesn't exist?

Sorry if this is a stupid question, i'm a noob c programmer.

I really don't know the answer either. I ended up trying an experimental 2.6.38 kernel built from 3 different git trees to test my wireless stuff so I didn't look into this too closely.

I'm not really a kernel hacker so I'm not sure whats going on with compat-wireless.

Thanks very much for your help.

I may try later...

Hi.

The reason for this is a missing directory in the sources package (it's a known bug).
Just get and symlink/copy the /arch/arm/plat-mxc/include/mach directory from the Git repo to your headers under a mach/ directory.


Best regards,
Johan
