You pass all other options as you would when you open the command-line compilers. The following example sets
the locale and source path when compiling MyApp:
java -jar ../lib/mxmlc.jar +flexlib c:/flex_3_sdk/frameworks -locale en_US -source-path
locale/{locale} c:/flex3/MyApp.mxml
About configuration files
Configuration files can be used by the command-line utilities and Flex Builder compilers.
Flex includes a default configuration file named flex-config.xml. This configuration file contains most of the
default compiler settings for the application and component compilers. You can customize this file or create your
own custom configuration file.
Flex SDK includes the flex-config.xml file in the flex_install_dir/frameworks directory.
The Flex Builder compilers do not use a flex-config.xml file by default. The default settings are stored internally.
You can, however, create a custom configuration file and pass it to the Flex Builder compilers by using the
load-
config
option. Flex Builder includes a copy of the flex-config.xml file that you can use as a template for your
custom configuration file. This file located in the flex_builder_install_dir/sdks/sdk_version/frameworks directory.
You can generate a configuration file with the current settings by using the dump-config option, as the following
example shows:
mxmlc -dump-config myapp-config.xml
Locating configuration files
You can specify the location of a configuration file by using the load-config option. The target configuration
file can be the default flex-config.xml file, or it can be a custom configuration file. The following example loads a
custom configuration file:
compc -load-config=myconfig.xml
If you specify the filename with the += operator, your loaded configuration file is used in addition to and not
instead of the flex-config.xml file:
compc -load-config+=myconfig.xml
With the mxmlc compiler, you can also use a local configuration file. A local configuration file does not require
you to point to it on the command line. Rather, Flex examines the same directory as the target MXML file for a
configuration file with the same name (one that matches the filename-config.xml filename). If it finds a file, it uses
it in conjunction with the flex-config.xml file. You can also specify a configuration file by using the
load-config
option with the
+= operator.
