Hi,
I have compiled and installed an RT_PREEMPT patched kernel (2.6.33.7-rt29) on a AT91SAM9260 board.
I'd like to test latencies using cyclictest software (obtained from git repository).
My cross compile environment is gcc-4.2.3 with glibc-2.3.3 (obtained from the producer of the board).
This is the error I get when I try to compile:
$ make CROSS_COMPILE=arm-unknown-linux-gnu- librttest.a

Thank you for any suggestions and help.
