Use the target-player compiler option
to specify the version of Flash Player that you want to target with
the application. Features requiring a later version of Flash Player
are not compiled into the application.
One reason for setting the target Player version is if you are
unsure of Player usage penetration rates and want to choose a Player
version that is lower than the most recent one. Another reason is
if your users are locked in to a particular Player version, such
as when they are on an intranet and cannot upgrade.
The target-player option has the following syntax:
The major_version is required while minor_version and revision are
optional. If you do not specify the minor_version or revision,
the compiler uses zero.
For Flex 4.0, the only supported value of the target-player option
is 10.0.0. For Flex 4.1, the default value is 10.1.0. For Flex 4.5,
the default value is 10.2.0. For Flex 4.6, the default value is
The minimum value for Flex 4.6 is 11.1. The minimum value for
Flex 4.5 is 10.2.0. For Flex 4.0 and 4.1, the minimum value is 10.0.0
(although Flex 4.1 included Player 10.1).
If you do not explicitly set the value of this option, the compiler
uses the default from the flex-config.xml file.
SWF version (advanced)
The swf-version compiler option specifies the
SWF file format version of the output SWF file. Features requiring
a later version of the SWF file format are not compiled into the
application. This is different from the Player version in that it refers
to the SWF specification versioning scheme.
For example, to compile an application to version 10 of the SWF
specification, use the following:
This is an advanced option that you should only use if you have
an understanding of the SWF specification that you are targeting.
