Hello,

I have a Unity project that built fine on XCode, and once adding GoogleMobileAds it will not build.

I am devloping on

Windows 10 PC,

Unity vers 2017.4.301f

I have been successfully compiling 64bit aab files using IL2CPP for several months now,

Using gradle default builder, not experimental, with no custom gradle template.

I installed GooglePlayGPlugin-0.9.50/. unitypackage

and running Play-services-resolver-1.2.135.0 as well

Both have been working fine, and have successfully compiled 64 bit aab files for Google Play.

Installed GoogleMobileAds v4.1.0.unitypackage

Yesterday, I exported XCode project with GoogleMobile AdsSDK for the first time on this project.

We transfer and compile on Mac:

Mac OS Sierra 10.13.6 running
XCode v10.1 (10B61)

We do not use Cocopods, so we add frameworks manually.

I manually installed the following frameworks for sharing, game center, and ads, we typically

require these frameworks for GooogleMobileAds.framework to build with our other assets:

Gamekit.framework
MessageUI.framework
Metal.framework
Webkit.framework
Social.framework
CoreLocation.framework
AdSupport.framework
CoreTelephony.framework
GLKit.framework
MobileCoreServices.framework
Security.framework
Storekit.framework

Our workflow lists those as resolving many of the previous Mach-O linker errors for GMAD 3.13.0.

Also, we followed the instructions listed here:

https://developers.google.com/ad-manager/mobile-ads-sdk/ios/quick-start

In XCode we added:

And added the OtherLinker flags -ObjC
And added plist key: GADIsAdManagerApp = bool Yes

For this project we Installed Google IOS SDK 7.53.0

From GoogleMobileAdssdkios-7.53.0.zip file we added the following frameworks:

GoogleMobileAds.framework (we're accustomed to this file from GMAds 3.13.1)
GoogleAppMeasurement.framework (new to us)
GoogleUtilities.framework (new to us)
nanopb.framework (new to us)

We are assuming all 4 frameworks must be included in the XCode project.

We are getting the following build errors:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Are these 3 new additional frameworks required for base functionality of banners, interstitial, and rewarded ads?

GoogleAppMeasurement.framework (new to us)
GoogleUtilities.framework (new to us)
nanopb.framework (new to us)

Is this caused by the new version of GoogleMobileAds4.1.0 not being incompatible with our version of XCode 10.1.?

Can anyone please assist in resolving this build error?

Thank you for your time, please let me know if additional information is required.

Hi there,

Thank you for providing an extensive rundown of your concern

Since you mentioned that you installed GoogleMobileAds v4.1.0.unitypackage, then all of the required dependencies should be added automatically upon exporting it to iOS project; there is no need for you to add those dependencies you mentioned manually. With this, could you please re-export your Unity project to iOS project again, then immediately build and run it on your device?

Regards,
