bpkg-cfg-create - Man Page

create configuration


bpkg cfg-create|create [options] [cfg-args]
bpkg cfg-create|create [options] --existing|-e

cfg-args = (module | cfg-var)...


The cfg-create command creates a new bpkg configuration with the specified build2 modules and configuration variables (the first form) or initializes one based on an existing build system configuration (the second form). The bpkg configuration itself is a build system configuration; see build system driver (b(1)) create meta-operation for details.

Unless the --existing|-e or --wipe option is specified, cfg-create expects the configuration directory to be empty or to not exist (in which case it will be created).

By default, the configuration created with the first form loads the config, test, dist, and install modules. However, additional modules and, if required, their configuration variables can be specified as the cfg-create arguments. For example:

bpkg create cxx config.cxx=clang++ config.install.root=/usr/local

By default, bpkg appends .config to the names of the modules that you specify so that only their configurations are loaded. You can override this behavior by specifying the period (.) after the module name. You can also instruct bpkg to use the optional module load by prefixing the module name with the question mark (?). For example:

bpkg create cxx. "?cli"

Cfg-Create Options

--directory|-d dir

Create the configuration in dir rather than in the current working directory.


Initialize a bpkg configuration based on an existing build system configuration.


Wipe the configuration directory clean before creating the new configuration. For safety, this option requires that you specify the configuration directory explicitly with --directory|-d.

Default Options Files

See bpkg-default-options-files(1) for an overview of the default options files. For the cfg-create command the search start directory is the parent directory of the new configuration. The following options files are searched for in each directory and, if found, loaded in the order listed:
