1 21) perf build 3============= 4The perf build process consists of several separated building blocks, 5which 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 11Several 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 30Please refer to tools/build/Documentation/Build.txt for more 31information about build framework. 32 33 342) perf build 35============= 36The Makefile.perf triggers the build framework for build objects: 37 perf, libperf, gtk 38 39resulting in following objects: 40 $ ls *-in.o 41 gtk-in.o libperf-in.o perf-in.o 42 43Those 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 47 48NOTE this description is omitting other libraries involved, only 49 focusing on build framework outcomes 50
