Re: LTTng 0.62 on omap 1611

Hi Mathieu,

I have tried to compile LTTng version 0.6.41, but unfortunately I got this
error message:

  CC      arch/arm/kernel/asm-offsets.s
In file included from include/linux/spinlock_types.h:13,
                 from include/linux/spinlock.h:79,

                 from include/linux/sched.h:45,

make: *** [prepare0] Error 2

  HOSTLD  scripts/mod/modpost

So I've tried, disabling Toolkit and Facility Locking and then it shows
problems during linking process, as follows:

  LD      init/built-in.o
  LD      .tmp_vmlinux1
ltt/built-in.o: In function `ltt_force_switch':
ltt/ltt-relay.c:649: undefined reference to `cmpxchg'
ltt/built-in.o: In function `ltt_ioctl':

ltt/built-in.o: In function `ltt_relay_reserve_slot':
ltt/ltt-relay.c:966: undefined reference to `cmpxchg'
ltt/ltt-relay.c:990: undefined reference to `cmpxchg'
make: *** [.tmp_vmlinux1] Error 1

Do you have a suggest where might be the problem?

Liselene
