Flex 4.6 AIR 19 iOS 9 ADT package fail: library not found for -ISystem.B

[stolennickname]

Immediately upon upgrading to Xcode 7 and trying to debug my Flex AIR project, it fails to package for iOS. This is occurring when attempting to debug on device (iPad 2 iOS 9). Alert:

---------------------------------------

Create iOS Package

Id: library not found for -ISystem.B

Id: library not found for -Igcc_s.1

Compilation failed while executing : Id64

…

---------------------------------------

Both Adobe Flex 4.6.0 overlaid with AIR 18.0.0.199 and Adobe Flex 4.6.0 overlaid with AIR 19.0.0.193 fail with the same error.

In addition, debugging in the Simulator yields another warning upon launch:

---------------------------------------

Launch iOS Application

[MT] DVTAssertions: Warning in /Library/Caches/com.apple.xbs/Sources/DVTFrameworks/DVTFrameworks-8201/DVTFoundation/PlugInArchitecture/PlugInManager/DVTPlugInManager.m:257

Details: Requested but did not find extension point with identifier Xcode.DVTFoundation.DevicePlatformMapping

Object:

Method: -extensionPointWithIdentifier:

Thread: {number = 1, name = main}

Please file a bug at http://bugreport.apple.com with this warning message and any useful information you can provide.

---------------------------------------

The first failure is really the block. I can't meaningfully work on the project until this is addressed. Any fix suggestions welcome, TIA.

This issue seems to be an old bug that has resurfaced, tied to the old Adobe Flex compiler, Java, and Xcode: Compilation failed while executing : ld64

For the record, I'm on OS X 10.10.5, with Java 1.8.0_25. Error occurs in both IntelliJ IDEA 15 and Flash Builder 4.7.

Hi, I have exactly the same problem. Tried to update Adobe AIr to the newest version 19. Overlaid over Flex 4.6 in Flash Builder. Tried different settings inside the Platform Option file to package ANE.

I'm still getting the missing lib while trying to run the Application on my Iphone 6.

I added in the Platform Option :

<option>-lSystem.B</option>

<option>-lgcc_s.1</option>

But It didn't work.

Workaround: Use an earlier iOS SDK, such as 8.1.

I have a separate iOS 8.1 SDK folder that I saved out, and use as the SDK source for the compile. It gives no problems.

This remains a serious open bug with the current release version of AIR 19.0.0.190 and the current beta version of AIR 19.0.0.193 for legacy compiler Flex projects targeting iOS 9 SDK. I haven't yet tested it against a pure ActionScript ASC 2 project, so the problem may be present there as well. I would like to get my AIR project compiled with the iOS 9 SDK as it is headed to the App Store in just a couple of weeks.

The Simulator warning I posted above has gone away after a run of Xcode and a reboot. Possibly a vestigial issue with a fresh Xcode install.

Compiling with iOS SDK 8.4 also works.

iOS SDK 9.0 remains problematic.

Xcode 7 has changed the enclosed library file format from .dylib to .tbd. This may be part of the issue. How do I link against .tbd files in Xcode 7? | Apple Developer Forums

The old dylibs seem to still be around in /usr/lib, but I lack the savvy to know how to link to them with AIR.

[Roshan_Chhetri · Accepted solution]

Please follow the following Workaround  [Applicable only for MAC]

1. Download and install Latest Xcode version 7 (we tried on xcode7.2 beta )

2. Create a soft link or Copy the ld from Xcode path : /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bi n/ld  to <FLEX_SDK_PATH>/lib/aot/bin/ld64/ld64

I hope it solves the issue.

[stolennickname]

Thanks so much Roshan. Copying the file from Xcode 7 (current release version) to the Flex + AIR SDK and renaming it did the trick. I can now debug on device as well as package release builds.

The resulting ld64 is 0.5 MB smaller than the AIR version and doesn't include the Adobe patch modifications, but it is working.

Hopefully this will be addressed as an updated ld64 in a future update to AIR.

[Roshan_Chhetri]

Yes for sure

I did all the steps you listed. Now when trying to debug through the iOS Simulator I got the following message:

Error occurred while packaging the application:

ld: building for iOS, but linking in object file built for OSX, file 'extensionglue.o' for architecture i386

Compilation failed while executing : ld64

The "fix" listed here feels like a real hack. I continue to get anomalous compiling errors using the iOS SDK included with Xcode 7.x. I've given up on this hack and wish I could revoke the "answered" status of this post.

Workaround: I strongly recommend compiling against the SDK included with Xcode 6.4. It's obscured, but you can download older versions of Xcode from the Apple Developer site. Some links listed at ios - How to download Xcode 4 / 5 / 6 / 7 and get the DMG file? - Stack Overflow

You can have two versions of Xcode installed at the same time, just segregate them by name or folder placement. You may also have to run the xcode-select command to mark which version is the active one you are targeting. Terminal psuedocommand:

sudo xcode-select -switch /Applications/PathToTargetXcode.app

Adobe AIR seems like it needs a lot of work to compile against the up-to-date iOS 9.1 SDK. We eagerly await a new version of AIR that is capable.

Does AIR 20 beta solved the bug?

[ivanp2689695]

Yes, it does!

[Aymeric-]

Does this bug makes dylib linking issues like this one?

[ivanp2689695]

Have to do this procedure with every AIR build update. What's up Adobe, can't you fix it?

[Calibrae]

Ok, so, with AIR 21, it's still a bug? Seriously? And as said earlier, you can't compile to the simulator anymore...

[Roshan_Chhetri]

Hi Calibrae‌,

Kindly let us know the issue you face with respect to SDK 21 such that we can help you on the same.

I'm seeing this issue in Air 27 when including iOS 11

ld: library not found for -lgcc_s.1

Compilation failed while executing : ld64

I've tried the workaround.  Replacing ld64 in the ld64 directory within AIR with the one from xCode-beta (9.0 beta 6) - nothing changes, I'm seeing the same error..

Thank you el111​ that did the trick!

I am still having issues with Flash Builder 4.7, Mac OS X High Sierra 10.13.6 and latest AIR SDK 31.

I have copied to ld file to AIR SDK  aot bin folder and renamed it as ld64 and that error is gone.

BUT I HAVE NEW ERROR:

Error occurred while packaging the application:

Compilation failed while executing : ld64

This only happens when I try to run iOS application on iOS Simulator.

When I debug application normally everything is fine.

How to resolve this issue?
