CoronaSDK 2015.2722 - Unable to build for iOS when Vungle plugin enabled

Solar2D Daily Builds and Public Releases
#1

Environment 

Code: Sample code attached

CoronaSDK: 2015.2722

OSX: 10.10.5

XCode: 7.0 (7A220)

I hope the community can help with this particular issue. When the Vungle Ad plugin is enabled, Corona was unable to build for iOS. Android is fine. I have been consistently able to reproduce this on my Mac laptop and a fresh laptop which did not previously have XCode and Corona SDK installed.

Conditions

Full build.settings attached. iOS Build fails when Vungle plugin is defined. Build is fine when disabled. Note that my app depends on Vungle for income and so cannot be disabled.

plugins = 

    {

        [“CoronaProvider.ads.vungle”] =

        {

            publisherId = “com.vungle”,

        },

    }

Try building with a blank main.lua and the attached build.settings.

Error

Specifically, the error I am seeing when building for iphone+ipad:

Can anyone identify if this is a bug with Corona? This issue also occurs with the last 5 nightly builds.

Many thanks

Rob,

I am having the same exact problem. So, I went back to build 2646 which had previously been successful when building. But, now it no longer builds. I’m getting the same build error: There is a problem linking the app. If I comment out the Vungle plugin in my build settings it builds just fine. I was hoping to release an update to my app this weekend but with this problem I’ll not be able to do so. Please let us know when you find a solution.

Thanks,

Guy

#4

Vungle pushed a plugin yesterday that’s causing the issue. It doesnt matter what version of Corona you’re using. It’s Sunday so this may not get fixed until Vungle can fix this on Monday.

#5

Thanks Rob! Hopefully they’ll get right on it first thing Monday.

#6

Thanks for the feedback Rob (especially on a Saturday!). I’ll retest once Vungle issues a fix and I’ll report back to this thread.

#7

I reported this to Vungle today. Chris Mock from Vungle got back to me with this –

Thanks for writing in about the build error with Corona. This error ““Undefined symbols” and “linker command failed” error” has been identified and the issue has been fixed. The plug-in configuration was missing reference to WebKit framework, which has now been adjusted in the configuration and submitted. Please do let us know if you continue to experience a build error. I will reply to the post on the forums this has been identified and fix pushed.

I can now successfully build my apps. Haven’t gotten around to testing the actual Vungle Ads though. Will report back with my findings tomorrow.

#8

Unfortunately, the new Vungle SDK fails to initalize (ads.init) on iOS 6. iOS versions 7 and above don’t have this problem.

I’ve reported this to Vungle again.

#9

Chris Mock from Vungle has confirmed that they’ve now dropped support for iOS 6. Going forward, Vungle ads will only work on iOS 7+ devices.

Just to be clear -

If you’re still supporting iOS 6 in any of your apps, and if you’re using Vungle ads in those apps, and they’re already available on the App Store, they will continue to work fine on iOS 6 devices as long as you don’t update those apps. Going forward, if you update them, you’ll automatically pull the latest Vungle plugin for your builds because of which those apps will fail on iOS 6 devices. iOS 7+ devices are unaffected altogether.

#10

Apple officially supports the current release of iOS and two versions back. If you’re building with iOS 9, then only iOS 8 and iOS 7 are supported. If you want to still support iOS 6 (under 5% of installed devices), you’re going to have to stay on an older version of Corona, but by February, Apple will probably require everything submitted to be based on iOS 9 anyway. They did this last year with iOS 8.

#11

Many thanks to everyone involved in contacting Vungle for the recent fix. I can confirm Vungle Ads are working for iOS (version 7+)

#12

Thanks for fixing this guys - Its solved my problem too.

I raised a bug (Case No. 43109) and it can now be closed :slight_smile:
