Flex 4.6 IOS Compiler


I've recently updated my Flex SDK version to 4.6 in the hopes that my IOS application's performance will improve. Unfortunately I cannot successfully compile my application in the "standard" compile mode (The super slow one). From what I can see from the error log produced by Java (The ADL compiler from adobe is written in Java) I'm running out of memory.

The compiler is using a lot of memory (1.5GB) but that is not near the physical limit of my PC which has 4GB installed. I'm running a 64bit version of Windows 7 (Edit: Problem is reproducable using the 32 and 64bit java runtimes).

Any idea folks? Posted below is the error log:

Your VM arguments are:

jvm_args: -Xss1500K -Xms256m -Xmx1024m

which is probably why you're running out of heap space.

Try tweaking your memory settings when you start Flex.

I'm running a 64bit version of Windows 7.

Try to use Java x64 binaries for compiling.

answered on Stack Overflow Jan 23, 2012 by focus

There is such kind of tool like http://visualvm.java.net/

Similar to Apple's profiler utilities, you can use it to connect to your Eclipse session and record the memory usage to prove previous posts or you could determine the point of fail during compilation into the ARM binaries.

Alternative way could be to try ANT compiler with specific options.

Or at least make a proof-of-fail project and make it public, so people could test it too.

Even if you have big physical RAM it not means that it is enough. The Flex using a lot of memory to compile and size may (or may not) depends on the size of project you made. Windows have good technics for swapping memory to use hard disk space to extend RAM. Please ensure that you have enough free disk space and setup swapping to use that disk. Please check swap/paging settings in windows using this instruction: http://helpx.adobe.com/x-productkb/global/set-virtual-memory-paging-default.html

P.S. I had same issue and to solve it I just free up several gigabytes of space in system drive, after which compilation in Flex for iOS was fine.
