I am trying to install the Google maps SDK and I am running through this error when running:

Answer 1

I noticed the following changes when I upgraded an app that was using the older Google maps SDK that had been installed manually:

• Need to link to CoreBluetooth.framework and Accelerate.framework in Build Phases -> Link Bundle with Libraries.
• The -all_load flag under "Other Linker Flags" will cause "duplicate symbol" errors. (Use -ObjC instead.)

If you use the CocoaPods method of installation (per their current instructions), it should take of the required frameworks but it'll still get messed up by -all_load.

Answer 2

make sure following are included

GoogleMaps SDK framework and bundle

GoogleMaps (with .framework extension) is present at your root directory (where your .xcodeproj is)

GoogleMaps (with .bundle extension) is referenced in your xcode project

Following Frameworks

Accelerate.framework

AVFoundation.framework

CoreBluetooth.framework

CoreData.framework

CoreGraphics.framework

CoreLocation.framework

CoreText.framework

GLKit.framework

ImageIO.framework

libc++.dylib

libicucore.dylib

libz.dylib

OpenGLES.framework

QuartzCore.framework

Security.framework

SystemConfiguration.framework

Build Settings

Architecture value in your project settings includes armv7.

Other Linker Flags has -ObjC , if not present add it

Answer 3

**_vImageBoxConvolve_Planar8, referenced from: (anonymous namespace)::CreateBlurredImage(CGImage*, double, double) in GoogleMaps(GLWaterGroup.o)**

This required "Accelerate.framework". So, please add it.

Steps:
1)Build Phases -> Link Bundle with Libraries.
2)Click "+",
3)Select "Accelerate.framework". Finish.

===================================

Others errors required "CoreBluetooth.framework. So, please add it also in similar way.

Answer 4

It looks like Google's API needs CoreBluetooth for Beacon location. Link against CoreBluetooth.framework in your build phases and everything should be fine.

EDIT: Make sure to install GoogleMaps through those instructions to avoid any issue: https://developers.google.com/maps/documentation/ios/start
