NAME

6       meson - a high productivity build system
7

DESCRIPTION

9       Meson  is  a build system designed to optimize programmer productivity.
10       It aims to do this by providing simple, out-of-the-box support for mod‐
11       ern  software development tools and practices, such as unit tests, cov‐
12       erage reports, Valgrind, Ccache and the like.
13
14       The main Meson executable provides many subcommands to access  all  the
15       functionality.

17

The setup command

19       Using  Meson is simple and follows the common two-phase process of most
20       build systems. First you run Meson to configure your build:
21
22       meson setup [ options ] [ build directory ] [ source directory ]
23
24       Note that the build directory must be different from the source  direc‐
25       tory.  Meson  does not support building inside the source directory and
26       attempting to do that leads to an error.
27
28       After a successful configuration step you can build the source by  run‐
29       ning the actual build command in the build directory. The default back‐
30       end of Meson is Ninja, which can be invoked like this.
31
32       ninja [ target ]
33
34       You only need to run the Meson command once: when you  first  configure
35       your  build  dir. After that you just run the build command. Meson will
36       autodetect changes in your source tree and regenerate all files  needed
37       to build the project.
38
39       The  setup  command  is  the default operation. If no actual command is
40       specified, Meson will assume you meant to do a setup. That  means  that
41       you can set up a build directory without the setup command like this:
42
43       meson [ options ] [ build directory ] [ source directory ]
44
45
46   options:
47       --version
48              print version number
49
50       --help print command line help
51
52

The configure command

54       meson  configure  provides  a way to configure a Meson project from the
55       command line.  Its usage is simple:
56
57       meson configure [ build directory ] [ options to set ]
58
59       If build directory is omitted, the current directory is used instead.
60
61       If no parameters are set, meson configure will print the value  of  all
62       build options to the console.
63
64       To set values, use the -D command line argument like this.
65
66       meson configure -Dopt1=value1 -Dopt2=value2
67
68

The introspect command

70       Meson  introspect is a command designed to make it simple to  integrate
71       with other tools, such as IDEs. The output of this command is in JSON.
72
73       meson introspect [ build directory ] [ option ]
74
75       If build directory is omitted, the current directory is used instead.
76
77
78   options:
79       --targets
80              print all top level targets (executables, libraries, etc)
81
82       --target-files
83              print the source files of the given target
84
85       --buildsystem-files
86              print all files that make  up  the  build  system  (meson.build,
87              meson_options.txt etc)
88
89       --tests
90              print all unit tests
91
92       --help print command line help
93
94

The test command

96       meson  test  is a helper tool for running test suites of projects using
97       Meson.  The default way of running tests is to invoke the default build
98       command:
99
100       ninja [ test ]
101
102       meson test provides a richer set of tools for invoking tests.
103
104       meson  test  automatically  rebuilds the necessary targets to run tests
105       when used with the Ninja backend.  Upon build failure, meson test  will
106       return  an  exit code of 125.  This return code tells git bisect run to
107       skip the current commit.  Thus bisecting using git can be  done  conve‐
108       niently like this.
109
110       git bisect run meson test -C build_dir
111
112
113   options:
114       --repeat
115              run tests as many times as specified
116
117       --gdb  run tests under gdb
118
119       --list list all available tests
120
121       --wrapper
122              invoke all tests via the given wrapper (e.g. valgrind)
123
124       -C     Change  into  the  given directory before running tests (must be
125              root of build directory).
126
127       --suite
128              run tests in this suite
129
130       --no-suite
131              do not run tests in this suite
132
133       --no-stdsplit
134              do not split stderr and stdout in test logs
135
136       --benchmark
137              run benchmarks instead of tests
138
139       --logbase
140              base of file name to use for writing test logs
141
142       --num-processes
143              how many parallel processes to use to run tests
144
145       --verbose
146              do not redirect stdout and stderr
147
148       -t     a multiplier to use for test timeout values  (usually  something
149              like 100 for Valgrind)
150
151       --setup
152              use the specified test setup
153
154

The wrap command

156       Wraptool  is  a  helper utility to manage source dependencies using the
157       online wrapdb service.
158
159       meson wrap < command > [ options ]

161       You should run this command in the top level source directory  of  your
162       project.
