Actionscript 3 Actionscript项目的ByteArray问题

我正试图在FDT5IDE中为这个库创建一个项目 我创建了一个新项目：

文件->新建FDT项目->Web->AS3，然后点击完成

已在此处复制文件表单：

但是，IDE显示出项目中的问题：

我对AS开发非常陌生，我只想重新编译sa库

希望有人能帮忙

您需要先学习FDT设置教程。如果我没记错的话，你需要Flash Player 9+才能使用ByteArray类。不过，Flash Player 11是您最安全的赌注。下载Flex SDK并使用以下两个教程之一进行设置：

希望有帮助。

我尝试使用mxlmc，它会针对AS文件生成SWF，但是有很多警告，我不确定是否也编译了所有依赖项？
