linker command failed with exit code 1 (use -v to see invocation) (armv7) xcode

Question

I tried to compile my xcode project (i use xcode 4.5) and i have installed cordova 1,5 and the plugin BarecodeScanner on my project.

When i try to compile on iOs 6 ipod devices, i have the following error :

This error message is very complicated to understand... i searched on the web but found anything... Have you got any idea of the origin of this message ?

Thanks a lot,

Answer 1

What worked for me, was to set "Enable Bitcode" to "No" in the Build Settings > Build options.

Use the search on the top: http://screencast.com/t/xSCnqHGkhh

The error I was getting was:

XXX does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64

Also see this Question.

1. Make sure your Build Settings "Architectures" setting includes the target architecture (the processor chip) - armv7 for iOS 6, armv7s for iOS 7, etc.
2. If you have any third party libraries you link in, make sure they are built with the proper architecture support. Otherwise rebuild those libraries or check the developer for update downloads.
3. Finally, reopen the project with updated libraries, Clean, and Build.
4. You may also want to verify you have an up-to-date XCode with the right iOS supporting environments.

Answer 3

You might not have included any framework in your project. Go to

Project > targets > build phases > link binary with libraries

and add your missing framework.

Answer 4

I was getting the same error as well.

I resolved the issue on my end by using the following steps:

1. Going to the Build Settings for the Project.
2. Under the Settings > Valid Architecture settings, I had the values for Debug set to armv7 and armv7s. And I had the values for Release set to armv7 and armv7s.
3. I realized that the armv7s items were causing the problem. So I removed armv7s from both entries.

After that, I was able to archive my project with no issues.

Answer 5

Your project may be configured to target armv7 which is hindering the linker.

1. Select your project
2. Go to info tab
3. Remove Required Device Capability item if existing (may be armv7 called)
