| 2 | 1) perf build | |
| 3 | ============= | |
| 4 | The perf build process consists of several separated building blocks, | |
| 5 | which are linked together to form the perf binary: | |
| 6 | - libperf library (static) | |
| 7 | - perf builtin commands | |
| 8 | - traceevent library (static) | |
| 9 | - GTK ui library | |
| 10 | ||
| 11 | Several makefiles govern the perf build: | |
| 12 | ||
| 13 | - Makefile | |
| 14 | top level Makefile working as a wrapper that calls the main | |
| 15 | Makefile.perf with a -j option to do parallel builds. | |
| 16 | ||
| 17 | - Makefile.perf | |
| 18 | main makefile that triggers build of all perf objects including | |
| 19 | installation and documentation processing. | |
| 20 | ||
| 21 | - tools/build/Makefile.build | |
| 22 | main makefile of the build framework | |
| 23 | ||
| 24 | - tools/build/Build.include | |
| 25 | build framework generic definitions | |
| 26 | ||
| 27 | - Build makefiles | |
| 28 | makefiles that defines build objects | |
| 29 | ||
| 30 | Please refer to tools/build/Documentation/Build.txt for more | |
| 31 | information about build framework. | |

| 34 | 2) perf build | |
| 35 | ============= | |
| 36 | The Makefile.perf triggers the build framework for build objects: | |
| 37 | perf, libperf, gtk | |
| 38 | ||
| 39 | resulting in following objects: | |
| 40 | $ ls *-in.o | |
| 41 | gtk-in.o libperf-in.o perf-in.o | |
| 42 | ||
| 43 | Those objects are then used in final linking: | |
| 44 | libperf-gtk.so <- gtk-in.o libperf-in.o | |
| 45 | perf <- perf-in.o libperf-in.o | |
| 46 | ||

| 48 | NOTE this description is omitting other libraries involved, only | |
| 49 | focusing on build framework outcomes |
