It builds for me on Ubuntu. It looks like your 32-bit build setup is broken. The line that's failing to compile is: #include <time.h> Are you missing 32-bit headers? This test *can't* be run as a 64-bit binary. We could enable it to work as a 64-bit binary by merging this: http://lkml.iu.edu/hypermail/linux/kernel/1407.1/03739.html but it would still be nice to build the 32-bit version. I could try to rig up some makefile magic to skip building it if 32-bit headers are missing. --Andy > > :-/ > > Thanks, > > Ingo -- Andy Lutomirski AMA Capital Management, LLC -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
