Hi Evgeniy,
After r184405 I get compilation errors when building
"compiler-rt/trunk/lib/sanitizer_common/sanitizer_platform_limits_posix.cc".
The problem is caused by the lack of definition for `struct
input_keymap_entry' in my version of <linux/input.h>.
In my understanding, the problem is that r184405 requires at least a Linux
2.6.37.
To be more specific, it requires the following change:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/include/uapi/linux/input.h?id=607ca46e97a1b6594b29647d98a32d545c24bdff
I have a Ubuntu 10.04 with a linux 2.6.32-48-generic and a clean build of
the llvm compiler-rt (make && make install) fails for me.
I fixed the problem on my machine applying the patch in attachment to this
email which checks for the value of macro EV_VERSION (which should be the
version of the event structure; defined by input.h).
However I don't know enough about the sanitizer. I hope that this patch
can be of help.
Cheers,
Andrea Di Biagio
