253 | Instead of building a new perl binary, you can also build a standalone |
|

254 | application: |

255 | |
|
|
256 | # build the app |

333 | After writing out the bundle files, try to link a new standalone |
|
|
334 | program. It will be called C<name>, and the bundle files get removed after |
|
|
335 | linking it. |
|
|
336 | |
|
|
337 | The difference to the (mutually exclusive) C<--perl> option is that the |
|
|
338 | binary created by this option will not try to act as a perl interpreter - |
|
|
339 | instead it will simply initialise the perl interpreter, clean it up and |
|
|
340 | exit. |
|
|
341 | |
|
|
342 | This switch is automatically used when F<staticperl> is invoked with the |

|
343 | C<mkapp> command (instead of C<mkbundle>): |

344 | |
|
|
345 | To let it do something useful you I<must> add some boot code, e.g. with |
|
|
346 | the C<--boot> option. |
|
|
347 | |
|
|
348 | Example: create a standalone perl binary that will execute F<appfile> when |
|
|
349 | it is started. |
