 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.

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

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