You will then need to build and install lttng-modules against each of your
kernels.
lttng-modules (as any kernel module) installs under /lib/modules/$(uname -r),
where $(uname -r) evaluates to the kernel version you build against.
When building, it looks for your kernel headers by following
/lib/modules/$(uname -r)/build
or /lib/modules/$(uname -r)/source (I don't recall which).
You can override the directory it builds against by using the KERNELDIR
environment
variable.
Thanks,
Mathieu
