From: Simon Marchi Date: Mon, 6 Sep 2021 13:45:35 +0000 (-0400) Subject: tests: compile some tools/tests as C++ X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=729c1fec5976af17fded2f026725a08ef1924290 tests: compile some tools/tests as C++ These tests use things from the common libs, or at least include header files from src/common. These files are going to contain C++-specific things in a following commit, so it's easier if we compile them tools/tests as C++.
