6 bpkg-cfg-create - create configuration
7
9 bpkg cfg-create|create [options] [cfg-args]
10 bpkg cfg-create|create [options] --existing|-e
11 cfg-args = (module | cfg-var)...
13
15 The cfg-create command creates a new bpkg configuration with the speci‐
16 fied build2 modules and configuration variables (the first form) or
17 initializes one based on an existing build system configuration (the
18 second form). The bpkg configuration itself is a build system configu‐
19 ration; see build system driver (b(1)) create meta-operation for de‐
20 tails.
21 Unless the --existing|-e or --wipe option is specified, cfg-create ex‐
23 pects the configuration directory to be empty or to not exist (in which
24 case it will be created).
25 By default, the configuration created with the first form loads the
27 config, test, dist, and install modules. However, additional modules
28 and, if required, their configuration variables can be specified as the
29 cfg-create arguments. For example:
30 bpkg create cxx config.cxx=clang++ config.install.root=/usr/local
32 By default, bpkg appends .config to the names of the modules that you
34 specify so that only their configurations are loaded. You can override
35 this behavior by specifying the period (.) after the module name. You
36 can also instruct bpkg to use the optional module load by prefixing the
37 module name with the question mark (?). For example:
38 bpkg create cxx. "?cli"
40 Configurations can be linked with each other to allow a package to be
42 built in one configuration while its dependencies in one or more linked
43 configurations. This can be used to create a "base" configuration with
44 common dependencies that are shared between multiple configurations.
45 This mechanism is also used to provide a host configuration that is
46 used to build build-time dependencies.
47 Each configuration is assigned an automatically-generated UUID unless
49 one is specified with the --uuid option. This UUID is used to check the
50 integrity of configuration links. For convenience of referring to
51 linked configurations, a configuration can also be assigned a name with
52 the --name option.
53 A configuration also has a type specified with the --type option. Three
55 predefined types are target, host, and build2. If the type is not spec‐
56 ified explicitly, then target is assumed. When satisfying a dependency
57 of one package on another, a linked configuration will only be consid‐
58 ered if (1) it has the same type as the other configuration for run-
59 time dependencies, (2) it has the host type for regular build-time de‐
60 pendencies, and (3) it has the build2 type for build system module
61 build-time dependencies. Note that a host configuration is a target
62 configuration for the host machine. So to create a self-hosted configu‐
63 ration, use type host.
64 To link a configuration we use the bpkg-cfg-link(1) command. As a
66 shortcut, host and build system module configurations can also be
67 linked during the configuration creation with the --host-config and
68 --build2-config options, respectively. If a build-time dependency is
69 encountered in a configuration that has no linked configuration of a
70 suitable type (host or build2, nor is itself of a suitable type), then
71 a private host or build system module configuration named host or
72 build2, respectively, is created automatically inside the configura‐
73 tion's .bpkg/ subdirectory.
74
76 --directory|-d dir
77 Create the configuration in dir rather than in the current work‐
78 ing directory.
79 --existing|-e
81 Initialize a bpkg configuration based on an existing build sys‐
82 tem configuration.
83 --wipe Wipe the configuration directory clean before creating the new
85 configuration. For safety, this option requires that you spec‐
86 ify the configuration directory explicitly with --directory|-d.
87 --host-config dir
89 Link the specified host configuration with the configuration be‐
90 ing created as if by running the bpkg-cfg-link(1) command.
91 --no-host-config
93 Ignore any specified --host-config options.
94 --build2-config dir
96 Link the specified build system module configuration with the
97 configuration being created as if by running the bpkg-cfg-
98 link(1) command.
99 --no-build2-config
101 Ignore any specified --build2-config options.
102 --name name
104 The name of the configuration being created. If this configura‐
105 tion is linked with another configuration using bpkg-cfg-
106 link(1), this name will be used as the link name unless overrid‐
107 den. By default the configuration is created unnamed.
108 --type type
110 The type of the configuration being created. By default, config‐
111 uration of type target is created.
112 --uuid uuid
114 Use the specified UUID as the configuration id instead of gener‐
115 ating one automatically.
116
118 The common options are summarized below with a more detailed descrip‐
119 tion available in bpkg-common-options(1).

225 See bpkg-default-options-files(1) for an overview of the default op‐
226 tions files. For the cfg-create command the search start directory is
227 the parent directory of the new configuration. The following options
228 files are searched for in each directory and, if found, loaded in the
229 order listed:
230 bpkg.options
232 bpkg-cfg-create.options
233 The following cfg-create command options cannot be specified in the de‐
235 fault options files:
236 --directory|-d
