7 | This examples shows how to use LTTng-UST in a project that uses |
| 8 | CMake as the build system generator. | |
| 9 | ||
| 10 | Build the libraries and applications | |
| 11 | ===== | |
| 12 | ||
| 13 | ```bash | |
| 14 | mkdir build | |
| 15 | cd build | |
| 16 | cmake .. | |
| 17 | make | |
| 18 | ``` | |
| 19 | ||
| 20 | 3 shared libraries will be generated | |
| 21 | ||
| 22 | ``` | |
| 23 | libaligner-lib.so | |
| 24 | libtester-lib.so | |
| 25 | libtracepoint-provider.so | |
| 26 | ``` | |
| 27 | ||
| 28 | ||
| 29 | and 2 executables will be generated | |
| 30 | ||
| 31 | ``` | |
| 32 | aligner | |
| 33 | tester | |
| 34 | ``` | |
| 35 | ||
| 36 | ||
| 37 | ||
| 38 | Trace the application tester | |
| 39 | ============================ | |
| 40 | ||
| 41 | The script trace.sh can be used. | |
| 42 | ||
| 43 | ```bash | |
| 44 | lttng create | |
| 45 | lttng enable-event -u 'gydle_om:*' | |
| 46 | lttng start | |
| 47 | ./tester | |
| 48 | lttng stop | |
| 49 | lttng view > trace.txt | |
| 50 | cat trace.txt | |
| 51 | ``` | |
| 52 | ||
| 53 | The content of trace.txt should be: | |
