Ubuntu Networking :: How I Fixed Asus USB-N13 Compile Errors In Ubuntu 10.10

It seems with the newer linux headers, two functions changed their names slightly and caused a crash when attempting to build the Asus-provided USB-N13 drivers.

I'm still in the middle of getting the device to work, but actually compiling the driver was a major problem for me and others I've seen that complained of the breakage in 10.10.

Here's the fix:
Within the include/os/rt_linux.h and os/linux/rt_usb_util.c files, the usb_buffer_alloc and usb_buffer_free functions are part of an internal macro. These functions do not exist anymore and are replaced by the usb_alloc_coherent and usb_free_coherent respectively. Input parameters did not change, just the names.

The macro is defined in rt_linux.h and the functions are used in a symbol export within rt_usb_util.c. Simply renaming the functions should allow it to build.

As I said, I'm still in the process of getting the wireless to work, just wanted to let everyone know of the quick fix.

This issue will probably be addressed with a macro fix somewhere eventually.


#define usb_alloc_coherent(a, b, c, d) usb_buffer_alloc(a, b, c, d)
#define usb_free_coherent(a, b, c, d) usb_buffer_free(a, b, c, d)
