- Enable instrumentation and control tracing with the "lttng" command
from lttng-tools. See lttng-tools doc/quickstart.txt.
- - Note for C++ support: although an application instrumented with
- tracepoints can be compiled with g++, tracepoint probes should be
- compiled with gcc (only tested with gcc so far).
+ - Note for C++ support: since LTTng-UST 2.3, both tracepoints and
+ tracepoint probes can be compiled in C++. To compile tracepoint probes
+ in C++, you need g++ >= 4.7 or Clang.
