R – Compiling ActionScript 3 Files from the Command Prompt

actionscript-3apache-flex

I have a file Employee.as with the following source code. I am unable to compile it from the command prompt.

package Office{
    public class Employee{
        private var _firstName:String = "";

        public function get FirstName():String{
            return _firstName;
        }

        public function set FirstName(value:String):String{
            _firstName = value;
        }
    }
}

The error which I get is:

Error: A file found in a source- path must have the same package structure
'', as the definition's package, 'Office'.

Also, I want to know how to compile multiple files in a folder from the command line. I am planning to create a package with multiple files to form a library which I can use in my flex projects.

I was actually using the wrong command line options. I was earlier using mxmlc but on googling I found that for compiling libraries we have to use compc.

compc -source-path . c:/flexdeploy/comps/mypackage/ 
    -output c:/jrun4/servers/flex2/flex/WEB-INF/flex/user_classes/MyButtonComp.swc 
    -include-classes mypackage.MyButton

This solved my purpose.

Actionscript – compiling actionscript from command line using MXMLC

This is a two part question, so I will answer both separately.

Compiling two class files into one SWF

MXMLC will automagiclly compile all classes it finds from the entry point you give it (your main class). It finds classes from your import statements, and full class path definitions.

Here is a really good guide for using MXMLC command line to compile your AS3 projects. The article is a bit dated, but the information is still good. He goes into detail about the things you need to know when using the command line compiler, including the MXMLC options, writing BAT scripts, and a bit about AS3 that you can probably skip if you know what your doing.

Having more than one class in a file

AS3 allows you to have one class per file, plus as much "helper" classes as you like. It does not support protected and private classes like Java does. Helper classes are only visible in the file they are defined.

Helper classes sit outside the package declaration (which is a little weird to me). Here is an example:

package com.mynamespace
{
     public class Foo 
     {
          private var _fooHelper:FooHelper = new FooHelper();
     }
}

// helper class imports also go outside the package.
import com.example.xml.SaxHandler;
class FooHelper
{
     private var bar:Number = Math.random();
}

R – Lots of “incompatible signature” errors on Windows but not on Mac OS X with Flex 4 Gumbo

Are you sure it also compiles on Mac OS X? If you recently changed your build scripts but you are using the "incremental" compiler option, it might be building successfully on your Mac simply because of the cached build. Try removing any *.cache files and rebuild on your Mac to see if you get the same errors.

One way that you can get strange "incompatible signature" errors is if you place your output directory in the library path; for example, if you are outputting a *.swc file into $(MAINFOLDER)/lib and you also have $(MAINFOLDER)/lib listed in your library path. I suspect the reason for this is that, initially, the interfaces in your code will be used, but halfway through the build, the (incompatible) compiled interfaces will be used.
