ionic app build fails with error 'linker comma

Question

When attempting to build using ionic run ios -lc I am seeing the following error in terminal:

** BUILD FAILED **


The following build commands failed:
    Ld build/emulator/xXxXxXx.app/xXxXxXx normal i386
(1 failure)
Error code 65 for command: xcodebuild with args: -xcconfig,/Users/xXxXxXx/Projects/xXxXxXx/platforms/ios/cordova/build-debug.xcconfig,-project,xXxXxXx.xcodeproj,ARCHS=i386,-target,xXxXxXx,-configuration,Debug,-sdk,iphonesimulator,build,VALID_ARCHS=i386,CONFIGURATION_BUILD_DIR=/Users/xXxXxXx/Projects/xXxXxXx/platforms/ios/build/emulator,SHARED_PRECOMPS_DIR=/Users/xXxXxXx/Projects/xXxXxXx/platforms/ios/build/sharedpch

When attempting to build the same app in xCode I am seeing the error linker command failed with exit code 1 (use -v to see invocation)

• I've removed and added the ios platform
• I've updated ios-deploy
• I've updated ios-sim
• I've restarted Xcode
• I've restarted my machine Xcode is up to date
• I can build other projects successfully

Answer 1

The Xcode error linker command failed with exit code 1 (use -v to see invocation) led me to this stack overflow answer

The second answer there suggests a check for multiple / duplicate .m files in the Xcode project Compile Resources:

That can happen if the same .m file is referenced multiple times in your target's "Compile Sources" section in "Build Phases". Remove duplicate entries and you should be fine.

So I had a check in Xcode and there was indeed a duplicate call to a plugin resource.

After checking package.json I found the same plugin was referenced in two ways (with two paths).

Removing one of the two plugins resolved the issue.

Answer 2

the solution for my case was simply

cd platforms/ios

then:

pod install

Answer 3

I found the solution on github

the solution for me was open the .xcworkspace file insted of .xcodeproj located inside my '/platforms/ios' folder.
