   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 ```

  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:
  48
  49 ```
  50 [21:45:34.940246019] (+?.?????????) osiris gydle_om:alignQuery: { cpu_id = 2 }, { queryName = "moleculeX" }
  51 [21:45:34.940263188] (+0.000017169) osiris gydle_om:testAlignment: { cpu_id = 2 }, { alignment = "my-alignment" }
  52 ```
