Hi Marco,

Can you tell me which version of Mali DDK you're using, and the exact
command line to build it? My guts feeling is that the generated argument
for -I gcc flag is a file not a directory. The scons is not nicest to
debug.

Perhaps, I am going to hit the same problems, as I see that Ainol Novi is
quite cool, and I've started to look into this.

Did you try the Linaro distribution for the kernel?
