[ltt-dev] ltt/ltt-relay-alloc.c:46: error: 'cpu' undeclared

[Alan D. Brunelle]

I'm attempting to try out LTTng, but ran into this error after the
following steps:

(1) Git tree w/ Linus' "latest" tree - 2.6.27-rc8 (commit
4a7703582836f55a1cbad0e2c1c6ebbee3f9b3a7)

(2) Expanded patch-2.6.27-rc7-lttng-0.27.tar.bz2 into 'patches' directory

(3) Ran 'quilt push -a' which seemed to make a lot of patches...

(4) ran make:

  CC      ltt/ltt-tracer.o
ltt/ltt-tracer.c: In function ‘ltt_control’:
ltt/ltt-tracer.c:386: warning: ‘trace’ may be used uninitialized in this
function
ltt/ltt-tracer.c:386: note: ‘trace’ was declared here
  CC      ltt/ltt-relay.o
  CC      ltt/ltt-relay-alloc.o
ltt/ltt-relay-alloc.c: In function ‘relay_alloc_buf’:
ltt/ltt-relay-alloc.c:46: error: ‘cpu’ undeclared (first use in this
function)
ltt/ltt-relay-alloc.c:46: error: (Each undeclared identifier is reported
only once
ltt/ltt-relay-alloc.c:46: error: for each function it appears in.)
make[1]: *** [ltt/ltt-relay-alloc.o] Error 1
make: *** [ltt] Error 2


Looking at the patch patches/lttng-relay-alloc.patch shows that the
problem is in the patch.

Is this an issue w/ 2.6.27-rc8, and I should go back down to 2.6.27-rc7
- or is there just a bad patch?

Thanks,
Alan
