-Subject: [PATCH 1/1] don't build C++ example if a C++ compiler isn't
- available
-
-By default lttng-ust builds a hello.cxx C++ example that demonstrates
-the usage of the userspace tracing library in a C++ program.
-Unfortunately, when no C++ support is available, the build of lttng-ust
-fails just because of this example code. So we make the compilation of
-this code conditional on whether a working C++ compiler was found.
