34-

25+
There are 2 output directories - one for the build output and another for
26+
the installation of the build results, that is the utility, library,
27+
man pages, etc...
28+
29+
default directory
30+
-----------------
31+
32+
In the case of default directory, build and install process requires no
33+
additional parameters:
34+
35+
build
36+
-----
37+
38+
$ make
39+
40+
The output directory for the 'make' command is the current directory and
41+
its subdirs in the kernel tree:
42+
tools/power/cpupower
43+
44+
install
45+
-------
46+
47+
$ sudo make install
48+
49+
'make install' command puts targets to default system dirs:
50+
51+
-----------------------------------------------------------------------
52+
| Installing file | System dir |
53+
-----------------------------------------------------------------------
54+
| libcpupower | /usr/lib |
55+
-----------------------------------------------------------------------
56+
| cpupower | /usr/bin |
57+
-----------------------------------------------------------------------
58+
| cpufreq-bench_plot.sh | /usr/bin |
59+
-----------------------------------------------------------------------
60+
| man pages | /usr/man |
61+
-----------------------------------------------------------------------
62+
63+
To put it in other words it makes build results available system-wide,
64+
enabling any user to simply start using it without any additional steps
65+
66+
custom directory
67+
----------------
68+
69+
There are 2 make's command-line variables 'O' and 'DESTDIR' that setup
70+
appropriate dirs:
71+
'O' - build directory
72+
'DESTDIR' - installation directory. This variable could also be setup in
73+
the 'CONFIGURATION' block of the "Makefile"
74+
75+
build
76+
-----
77+
78+
$ make O=<your_custom_build_catalog>
79+
80+
Example:
81+
$ make O=/home/hedin/prj/cpupower/build
82+
83+
install
84+
-------
85+
86+
$ make O=<your_custom_build_catalog> DESTDIR=<your_custom_install_catalog>
87+
88+
Example:
89+
$ make O=/home/hedin/prj/cpupower/build DESTDIR=/home/hedin/prj/cpupower \
90+
> install
91+
92+
Notice that both variables 'O' and 'DESTDIR' have been provided. The reason
93+
is that the build results are saved in the custom output dir defined by 'O'
94+
variable. So, this dir is the source for the installation step. If only
95+
'DESTDIR' were provided then the 'install' target would assume that the
96+
build directory is the current one, build everything there and install
97+
from the current dir.
98+
99+
The files will be installed to the following dirs:
100+
101+
-----------------------------------------------------------------------
102+
| Installing file | System dir |
103+
-----------------------------------------------------------------------
104+
| libcpupower | ${DESTDIR}/usr/lib |
105+
-----------------------------------------------------------------------
106+
| cpupower | ${DESTDIR}/usr/bin |
107+
-----------------------------------------------------------------------
108+
| cpufreq-bench_plot.sh | ${DESTDIR}/usr/bin |
109+
-----------------------------------------------------------------------
110+
| man pages | ${DESTDIR}/usr/man |
111+
-----------------------------------------------------------------------
112+
113+
If you look at the table for the default 'make' output dirs you will
114+
notice that the only difference with the non-default case is the
115+
${DESTDIR} prefix. So, the structure of the output dirs remains the same
116+
regardles of the root output directory.
117+
118+
119+
clean and uninstall
120+
-------------------
121+
122+
'clean' target is intended for cleanup the build catalog from build results
123+
'uninstall' target is intended for removing installed files from the
124+
installation directory
125+
126+
default directory
127+
-----------------
128+
129+
This case is a straightforward one:
130+
$ make clean
131+
$ make uninstall
132+
133+
custom directory
134+
----------------
135+
136+
Use 'O' command line variable to remove previously built files from the
137+
build dir:
138+
$ make O=<your_custom_build_catalog> clean
139+
140+
Example:
141+
$ make O=/home/hedin/prj/cpupower/build clean
142+
143+
Use 'DESTDIR' command line variable to uninstall previously installed files
144+
from the given dir:
145+
$ make DESTDIR=<your_custom_install_catalog>
146+
147+
Example:
148+
make DESTDIR=/home/hedin/prj/cpupower uninstall
149+
150+
151+
running the tool
152+
----------------
153+
154+
default directory
155+
-----------------
156+
157+
$ sudo cpupower
158+
159+
custom directory
160+
----------------
161+
162+
When it comes to run the utility from the custom build catalog things
163+
become a little bit complicated as 'just run' approach doesn't work.
164+
Assuming that the current dir is '<your_custom_install_catalog>/usr',
165+
issuing the following command:
166+
167+
$ sudo ./bin/cpupower
168+
will produce the following error output:
169+
./bin/cpupower: error while loading shared libraries: libcpupower.so.1:
170+
cannot open shared object file: No such file or directory
171+
172+
The issue is that binary cannot find the 'libcpupower' library. So, we
173+
shall point to the lib dir:
174+
sudo LD_LIBRARY_PATH=lib64/ ./bin/cpupower
