Add Things - Legato Docs

After you've created your executable and turned it into an app (.adef), you can add others things you might need (e.g., a third-party library, some data files, a script or a legacy program built on another system).

To add other files to applications, you add other sections to your application's .adef file.

Here's a sample of how to add an audio file and a third-party library:

bundles:
{
    file:
    {
        [r]     audio/alert.wav     /usr/share/sounds/
 
        [r]     third-party/foo/lib/foo.so.1 /lib
    }
}

The file: subsection of the bundles: section will copy the file ./audio/alert.wav from the build host's file system (relative to the current working directory in which mkapp is run), and bundle it into the application such that it appears under /usr/share/sounds (from the application's point-of-view when it runs on the target).

The letter inside the square brackets (e.g., [r]) contain the permissions flags for the file on the target:

'r' = readable
'w' = writeable
'x' = executable

If you want to have a script or other executable run when the application starts, add that file to

the "file:" subsection of a "bundles:" section (with the executable flag [x] set), and
the list of executables in the processes section, "run:" subsection.

bundles:
{
    file:
    {
        [x]     otherProject/bin/bar    /usr/bin/bar
    }
}
 
processes:
{
    run:
    {
        (/usr/bin/bar)
    }
}

This grabs a copy of ./otherProject/bin/bar (relative to the directory where mkapp is run), puts it in the application sandbox's /usr/bin/bar directory, and starts one instance of it when the application starts.
