- (see tracepoint.h and tests/hello/tp.h).
- - Link application with -lust.
- - (TODO: start tracing with the "lttng" command from lttng-tools)
+ See lttng/tracepoint.h, and examples.
+ - Either compile the Tracepoint probes with the application:
+ - Use "-I." for the compilation unit containing the tracepoint
+ provider include (e.g. tp.c).
+ - Link application with "-ldl -llttng-ust".
+ - Example:
+ tests/hello/ hello.c tp.c ust_tests_hello.h Makefile.example
+ - Or compile the Tracepoint probes separately from the application,
+ using dynamic linking:
+ - Compile the tracepoint provider with "-I.".
+ - Link the tracepoint provider with "-llttng-ust".
+ - Link application with "-ldl".
+ - Set a LD_PRELOAD environment to preload the tracepoint provider
+ shared object before starting the application when tracing is
+ needed.
+ - Example:
+ - tests/demo/ demo.c tp*.c ust_tests_demo*.h demo-trace
+ - Enable instrumentation and control tracing with the "lttng" command
+ from lttng-tools. See lttng-tools doc/quickstart.txt.
