any idea ??

[dlech]

Remove the conflicting definitions from include/byteorder/swab.h in this repository?

[reboutte]

how can i do that ??

[dlech]

Edit the file in the directory that was created were checked out when you did git clone. Then run the dkms commands again.

[reboutte]

but i don't know how to remove the conflicting definitions ... edit a file, no problem, but , i don't "speak C++ fluently"

[reboutte]

Hello, the problem come from the ppc kernel, it work perfectly with intel kernel.... any idea?

[dlech]

You could try replacing

#include <byteorder/swab.h>

with

#include <linux/swab.h>

in include/byteorder/little_endian.h
