Can't Compile Apps for iOS6 using XCode 4.5 because of JMC

Question

This is the error I am getting:-

ld: file is universal (3 slices) but does not contain a(n) armv7s slice: /Users/sikosis/Dropbox/Code/Back2BackFM/Back2BackFM/JIRAConnect/JMCClasses/Libraries/CrashReporter.framework/CrashReporter for architecture armv7s

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

It's to do with JMC's CrashReporter.

You can download the PLCrashReporter source and build rev 454 or newer and replace the existing CrashReporter library that is bundled with JMC.  This has been working for me for without any issues using the current tip of JMC.

Warning: I don't actually know what ramifications that this will cause as I did this blindly without really looking at if this something that is acceptable.  ;-)  Perform at your own risk.

But building on the active architecture only, doesn't it mean that we will be unable to build for iPhone 5 ?

Phil Greenway · Answer

In Xcode's Targets, Build Settings ... I found a section called "Build Active Architecture Only" which was set to No.

I set it to Yes and then I was able to compile the app.
