FLATPAK BUILD-INIT(1)

NAME
flatpak-build-init - Initialize a build directory

SYNOPSIS

flatpak build-init [OPTION...] DIRECTORY APPNAME SDK RUNTIME [BRANCH]

DESCRIPTION

Initializes a separate build directory. DIRECTORY is the name of the directory. APPNAME is the application id of the app that will be built. SDK and RUNTIME specify the sdk and runtime that the application should be built against and run in. BRANCH specify the version of sdk and runtime

Initializes a directory as build directory which can be used as target directory of flatpak build. It creates a metadata inside the given directory. Additionally, empty files and var subdirectories are created.

It is an error to run build-init on a directory that has already been initialized as a build directory.

OPTIONS

The following options are understood:

-h, --help
    Show help options and exit.

--arch=ARCH
    The architecture to use. See flatpak --supported-arches for architectures supported by the host.

-v, --var=RUNTIME
    Initialize var from the named runtime.

-w, --writable-sdk
    Initialize /usr with a copy of the sdk, which is writable during flatpak build. This can be used if you need to install build tools in /usr during the build. This is stored in the usr subdirectory of the app dir, but will not be part of the final app.

--tag=TAG
    Add a tag to the metadata file. This option can be used multiple times.

--sdk-extension=EXTENSION
    When using --writable-sdk, in addition to the sdk, also install the specified extension. This option can be used multiple times.

--extension=NAME=VARIABLE[=VALUE]
    Add extension point info.

--sdk-dir
    Specify a custom subdirectory to use instead of usr for --writable-sdk.

--update
    Re-initialize the sdk and var, don't fail if already initialized.

--base=APP
    Initialize the application with files from another specified application.

--base-version=VERSION
    Specify the version to use for --base. If not specified, will default to "master".

--base-extension=EXTENSION
    When using --base, also install the specified extension from the app. This option can be used multiple times.

--type=TYPE
    This can be used to build different types of things. The default is "app" which is a regular app, but "runtime" creates a runtime based on an existing runtime, and "extension" creates an extension for an app or runtime.

--extension-tag=EXTENSION_TAG
    If building an extension, the tag to use when searching for the mount point of the extension.

--verbose
    Print debug information during command processing.

--ostree-verbose
    Print OSTree debug information during command processing.
