Native extension - compiler issue

Hi,

First, I compile an iOS app with a native extension developped by ADOBE : http://www.adobe.com/devnet/air/native-extensions-for-air/extensions/vibration.html#articlecontentAdobe_numberedheader_3

It's work well

Then, I made myself the iOS library on xcode. It's OK as well

Then, I made the ANE file following the tutorial http://custardbelly.com/blog/2011/09/21/air-native-extension-example-ibattery-for-ios/. It's seem OK

I create my air app with Flash Builder. I load ANE, SWC...everything seem ok

When I compile my Iphone Application with Flex, there is this error :

An erreor appears during the application packaging (my translation):

ld warning: in C:\\Users\\Tony\\AppData\\Local\\Temp\\c6468656-be35-4f05-8d51-0dd54063cefd/libcom.adobe.LEDTorch.a, file is not of required architecture

Undefined symbols:

  "_ExtInitializer", referenced from:

      _g_com_adobe_air_fre_fmap in extensionglue.o

ld: symbol(s) not found

Compilation failed while executing : ld64

.

Someone could help me?

I'm working on this bug for 2 days

Thanks in advance !
