Unable to deploy Unity3d project on iPhone device because of linking errors - xcode

I have created a xcode project using unity3d tool, while building the project for iOS my Player settings are like this:
1. Target Device: iPhone Only
2. Target Platform: Universal armv6+armv7 (OpenGL ES1.1+2.0) & I have tried it with armv6(OpenGL ES1.1)
3. SDK Version: iOS 4.3 & I have tried it with iOS Latest
4. Target iOS Version: 4.0
Api Compatibility Level: .Net 2.0 Subset, when I am trying to run it in iPhone I am getting the below mentioned error:
"__GetLookupStatus", referenced from:
Undefined symbols for architecture armv6: "__GetLookupStatus", referenced from: __Z19RegisterMonoModulesv in RegisterMonoModules.o
ld: symbol(s) not found for architecture armv6 clang: error: linker
command failed with exit code 1 (use -v to see invocation)
& my Unity 3 version is 3.4.2f3 & my Xcode version is 4.2.1.
How can I resolve this issue?

It is working now. I forgot to add my Objevtive-c files into Xcode project.

Switched Firebase Crashlytics from CocoaPods to Swift Package now Simulator won't build on a M1 Mac

Just removed Crashlytics from the podfile, then added it as a Swift Package. Built for an actual device just fine. But when I switch to the Simulator, no go (and tried deleting Derived folders etc - no change).
Another dev using Xcode 13.2.1 on an Intel Mac can build for the Simulator just fine.
Doesn't matter if I delete DerivedFolder then build first for Simulaor or for device - when I get to Simulator it always fails same errors.

I posted to Firebase Issues but this issue didn't ring a bell. However, I did trip on an Apple TN on M1 Mac build issues, and doing what they suggested revolved the issue.
It appears that when Xcode builds Packages the rules it follows may not use the target's build settings. I believe the issue was related to Excluded Architectures.
For me the issue was fixed by making sure Xcode was running in Rosetta mode.

Link error with Xcode 7 beta, address sanitization and CocoaPods + adMob

I successfully converted an iOS project to Xcode 7 beta + Swift 2 (it runs and the tests work).
However, when I turn on the new Address Sanitizer (option+run -> run -> Diagnostics -> Enable Address Sanitizer, I get the following message from the linker:
Undefined symbols for architecture x86_64:
"___asan_init_v5", referenced from:
_asan.module_ctor in libPods.a(Pods-dummy.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Seems to reference to CocoaPods which I use for the adMob pod.
I updated CocoaPods itself to the latest version and I updated the adMob Pod to the latest version.
Any hints how to get Address Sanitizer to work together with CocoaPods or the AdMob CocoaPod whichever causes this?

I am using latest Xcode and iOS version in my App.
Any help much appreciated!
I was able to build a universal library with support for the simulator by following the instructions here: Build fat static library (device + simulator) using Xcode and SDK 4+
I hope that helps you too.

USING PODS
pod 'ZBarSDK'
OR
Recompile ZBar for iphone 5. You can download recompiled ZBAR from here to skip the following
Steps
Download the source code (you must have Mercurial for mac):
Open Terminal and run following commands
a. hg clone http://zbar.hg.sourceforge.net:8000/hgroot/zbar/zbar
b. cd zbar
c. hg checkout iPhoneSDK-1.3.1
d. open iphone/zbar.xcodeproj
In the xcode project edit the "libzbar" scheme and select Release in Build configuration
Go to Build Settings set following Architectures
a. Architectures - >Standard architectures(armv7,armv72,arm64)
b. Valid Architectures -> arm64,armv7 armv7s
Compile libzbar for device AND for simulator, here the configuration:
Find the compiled libzbar.a and go in the folder using Teminal.app,
In My Case : /Users/kappe/Library/Developer/Xcode/DerivedData/zbar-gyozyrpbqzvslmfoadhqkwskcesd/Build/Products
In this folder you you should have two sub folder Release-iphoneos and Release-iphonesimulator
using xcode command line tools build your universal lib:
lipo -create Release-iphoneos/libzbar.a Release-iphonesimulator/libzbar.a -o libzbar.a
Now you can use the libzbar.a created, both in device and simulator.

xcode 4.5 - symbols not found for architecture i386 (zbar)

I have a project which uses the zbar-sdk (a barcode scanning library).
After updating my machine to xcode 4.5 and ios6sdk I am having some troubles.
I was able to build to the simulator without touching anything about my project. This is using the latest zbar 1.2 library.
I then wanted to build to my ios6 device for testing, and thats when I got an error.
After some googling on the zbar developer forum, I seen that I needed to get the zbar source and build the libzbar.a for armv7 and armv7s as this has not yet been done by the zbar developer.
See - http://sourceforge.net/projects/zbar/forums/forum/1072195/topic/5728912
So I did this, re-imported the updated libzbar.a into my project. I then built for my device, and it worked! I was able to get my app onto my testing device and the zbar barcode library worked fine.
I thought that was the end of it, but unfortunately not.
I then tried to build to the simulator (ios6) again, and thats when it fails.
No matter what I cannot get this project to build for both the device and simualtor at the same time and with the same settings :(
My libzbar.a project settings when building my own libzbar.a file:
Architecture: Standard (armv7, armv7s) $(ARCHS_STANDARD_32_BIT)
Build Active Architecture Only: No
Valid Architectures: armv7 armv7s
And my project settings (for myapp) as:
Architecture: Standard (armv7, armv7s) $(ARCHS_STANDARD_32_BIT)
Build Active Architecture Only: No
Valid Architectures: armv7 armv7s
Base SDK: iOS6
iOS Deployment Target: iOS 5.0
And the error when trying to build to the simulator:
ld: warning: ignoring file /Users/blah/iOS App/myapp/ZBarSDK/libzbar.a, missing required architecture i386 in file /Users/blah/iOS App/myapp/ZBarSDK/libzbar.a (2 slices)
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_ZBarReaderViewController", referenced from:
objc-class-ref in mycontroller.o
"_ZBarReaderControllerResults", referenced from:
-[mycontroller imagePickerController:didFinishPickingMediaWithInfo:] in mycontroller.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I have tried tweaking the libzbar.a project settings (e.g. build active architecture set to "YES") but this just results in neither the simulator or device working.
The fact that it works on the device but not the simulator makes me thing there is some weird architecture/project setting causing this.
Any help much appreciated!
I doubt this is the right answer but it worked for me, I compiled the new libzber.a using architectures: i386 armv6 armv7 armv7s in that order you also need to specify valid architectures as the same values. Again this is what worked for me with a recent release I needed to get out A.S.A.P. Both are found in Target -> Build Settings -> Architecures.
Also note: $(ARCHS_STANDARD_32_BIT) needed to be removed from the settings.
I fixed a similar issue by setting the iOS6 simulator architecture under OTHER_LDFLAGS in Target->Build Settings.
I forgot that I had a different command line argument for separated archituctures so I had to manually state the simulator

SDL in XCode 4.3.2 SDLMain.o undefined symbols

I have started trying to use SDL in Xcode 4.3.2 so I started up a Cocoa application for Mac OS X and connected all my frameworks : OpenGL, SDL etc. I don't have SDL_Image, SDL_Mixer etc. (Do I need these?) When I try to compile the project that just has SDLmain.h and SDLmain.m I get this error:
Undefined symbols for architecture x86_64: "_SDL_main", referenced from: -[SDLMain applicationDidFinishLaunching:] in SDLMain.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
I was having the same issue with SDL 1.2.15 on Xcode 4.5 and OS X 10.7, turned out the problem was that I added SDLMain.m and SDLMain.h (according to a suggestion on the libSDL website about OS X frameworks) to an existing SDL project which messed up with main. Bottom line is that you don't need those files just because you are using Cocoa -- SDL's own test apps don't use it either and run just fine on OS X.
