Part of my point is that the Ubuntu distribution is broken because it does
not install the easy-ust files. I have neither /usr/share/doc/lttng-ust/ nor
/usr/local/share/doc/ directories on my machines.
Note that Googling for "easy-ust" finds no git repositories except for the
one I quoted.
The Ubuntu distribution (liblttng-ust0) is 2.0.2, but it is nevertheless not
self-consistent because the man pages it installs for lttng-ust(3) mention
easy-ust. Could it be an lttng-ust distribution was (is) planned for Ubuntu
but hasn't made it "out there" yet, and the lttng-ust man pages were included
in liblttng-ust0 by accident?
There is a nearly complete mismatch between the Ubuntu lttng packages and
the lttng.org git repository, which is not conducive to one adding the contents
of the latter to what's installed by the former:
Ubuntu lttng.org git
liblttng-ctl-dev
liblttng-ctl0
liblttng-ust-dev
liblttng-ust0
liburcu-dev
liburcu1
lttng-modules-dkms lttng-modules.git
lttng-tools lttng-tools.git
lttng-ust.git
lttngtop lttngtop.git (2.0?)
I tried lttng-ust 2.0.2 (a367ee6) 2013-Apr-18 from http://git.lttng.org/.
Although lttng-ust itself compiles correctly (I only omitted the last step,
'sudo make install', in order to use the existing liblttng-ust 2.0.2
installation), easy-ust's make yields precisely the same error:
gcc -I. -c -o sample.o sample.c
gcc -I. -c -o tp.o tp.c
