My compile shell script can't work when using flex4 sdk beta2

Question

I worked with flex4 sdk beta 1, and the compile script worked well. for example:
mxmlc -debug=true -output=../main.swf -source-path ./src /usr/local/software/flash/open_source -- ./src/main.as
But, when i chang into beta2, it shows some errors which are about  RSL things as the follows:
D:\setup_bak\flashbuilder4beta2\testFlex4.as: 警告: 此编译单元不包含在 Frame 元
数据中指定的 factoryClass，无法加载配置的运行时共享库。要在没有运行时共享库的情
况下进行编译，请将 -static-link-runtime-shared-libraries 选项设置为 true，或删除
-runtime-shared-libraries 选项。
So I use -dump-config option to generate a config xml, when i using the config xml, i got an error as the follows:
错误: 必须指定目标文件
使用“mxmlc -help”可获得有关如何使用命令行的信息。
Any one can tell me why?
sorry for my english, i don't known whether i describe my problem clearly. Thank for reading this thread.

Answer 1

Compile success when i set -static-link-runtime-shared-libraries=true.
I thought that the size of swf would increase a lot because of a static link, but the size is 727 byte..
yes, it is a pure AS app extends Sprite. The code is so simple:
package
     import flash.display.Sprite;
     public class testFlex4 extends Sprite
         public function testFlex4()
the compile cmd which got an error is simple too:
mxmlc -debug=true -output=testFlex4.swf -source-path ./ -- testFlex4.as
the compile cmd which works find is:
mxmlc -debug=true -static-link-runtime-shared-libraries=true -output=testFlex4.swf -source-path ./ -- testFlex4.as
