If compiling from the git repository, run ./bootstrap before running
the configure script, to generate it.
+ Note that configure sets '/usr/local' as the default prefix for files it
+ installs. However, this path is not part of most distributions' default
+ library path which will cause builds depending on liblttng-ust to fail unless
+ '-L/usr/local/lib' is added to LDFLAGS. You may provide a custom prefix to
+ configure by using the --prefix switch.
USAGE:
object.
- 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.
