1 | This examples shows how to use LTTng-UST in a project that uses |
| 2 | CMake as the build system generator. | |
| 3 | ||
| 4 | Build the libraries and applications | |
| 5 | ===== | |
| 6 | ||
| 7 | ```bash | |
| 8 | mkdir build | |
| 9 | cd build | |
| 10 | cmake .. | |
| 11 | make | |
| 12 | ``` | |
| 13 | ||
| 14 | 3 shared libraries will be generated | |
| 15 | ||
| 16 | ``` | |
| 17 | libaligner-lib.so | |
| 18 | libtester-lib.so | |
| 19 | libtracepoint-provider.so | |
| 20 | ``` | |
| 21 | ||
| 22 | ||
| 23 | and 2 executables will be generated | |
| 24 | ||
| 25 | ``` | |
| 26 | aligner | |
| 27 | tester | |
| 28 | ``` | |
| 29 | ||
| 30 | ||
| 31 | ||
| 32 | Trace the application tester | |
| 33 | ============================ | |
| 34 | ||
| 35 | The script trace.sh can be used. | |
| 36 | ||
| 37 | ```bash | |
| 38 | lttng create | |
| 39 | lttng enable-event -u 'gydle_om:*' | |
| 40 | lttng start | |
| 41 | ./tester | |
| 42 | lttng stop | |
| 43 | lttng view > trace.txt | |
| 44 | cat trace.txt | |
| 45 | ``` | |
| 46 | ||
| 47 | The content of trace.txt should be: | |
