I'm trying to install LTTng on a Raspberry Pi 3 running Raspian Jessie (Debian). The directions say that with that distribution, I need to build it from source. When I do, and try to execute the make, I get the following error:

/usr/bin/make -C /lib/modules/4.4.34-v7+/build M=/tmp/tmp.tHMTTCom3X/lttng-modules-2.9.0 CONFIG_LTTNG=m CONFIG_LTTNG_CLOCK_PLUGIN_TEST=m modules
make[1]: Entering directory '/lib/modules/4.4.34-v7+/build'
make[1]: *** No rule to make target 'modules'.  Stop.
make[1]: Leaving directory '/lib/modules/4.4.34-v7+/build'
Makefile:110: recipe for target 'modules' failed
make: *** [modules] Error 2

(It looks to me that there is a rule for that target.)

Has anyone done this, or have any tips or ideas on how to do this?

Thanks!

You might be missing the headers for the running kernel, try installing the raspberrypi-kernel-headers package :

sudo apt-get install raspberrypi-kernel-headers

  • I see you are running a 4.4.34 kernel which is pretty recent with and older lttng-modules 2.5.1, that's not supported. You'll need to get a newer version of lttng, either 2.8 or 2.9. You can rebuild the source packages from debian testing on jessie or build from source. – Michael Jeanson Mar 01 '17 at 16:18
  • When I try to install, I can only seem to get heads/stable-2.5.0; I don't know why. I was trying to build from source when I ran into the original issue at the start of this thread. – jmk85204 Mar 02 '17 at 22:45
  • (meaning, when I use apt-get install, I can't get anything newer than that) – jmk85204 Mar 02 '17 at 22:58
  • You'll need to get the source packages from a newer debian release because your kernel is much more recent than the one shipped with a normal jessie system. – Michael Jeanson Mar 03 '17 at 18:57
