I guess the problems are related to the data types in the stats collection.

I am using the ARMEL target, just to be clear on this :). So is there a way to 
fix
this, ie. does the ARM architecture support atomic64_t structures or such?

I just pushed changes that should fix it. Can you pull again and try?

Weird. I'm not getting any error when cross compiling on ARM (kernel:
2.6.30.10-105.2.4.fc11). Whats the kernel version you are compiling against?

Anyway, I now pushed changes which explicitly includes spinlock.h which should 
solve
this. Can you please try again? Thanks.

If you still get any errors, please post full compiler output (not just error 
part)
in verbose mode (make V=1).

I believe that the kernel is 2.6.28-omap1, for the N900.

I'll try the new version.

GoogleCodeExporter commented 9 years ago 
Hmm the Maemo 5 headers do not contain the spinlock.h file, so the compilation 
still
fails ...

I don't understand Maemo installation setup but on Fedora, you need to have
kernel-devel (not kernel-headers) package in order to compile any module against
running kernel. This package also provides spinlock.h.

So, maybe you are missing corresponding package on Maemo?

Ok, it works now, thanks :). I did a wrong kind of merge and had to revert it 
to the
mercurial repository default.

Ok, at least the original bug due to atomic64_t is fixed. Thanks for reporting 
this :)
