Xcode 5 "Missing compiler spec LLVM 4.2" error

I am currently trying to build my project in Xcode 5. Build fails with error:

Dependency Analysis Error: missing compiler specification <XCCompilerSpecification: Some memory address here :'com.apple.compilers.llvmgcc42':MISSING:Default> for file

for all code files in project.

The project used to be built in Xcode 4.6 with LLVM 4.2 and now Xcode 5 only supports LLVM 5. So there is obviously something related to that here.

I have set the build settings in Xcode 5 to use LLVM 5 and the build still fails for the same reason. Has anyone encountered this before and know how to stop Xcode 5 from looking for LLVM 4.2 which it no longer supports?

This question is as a result of iOS 6 vs 7 appearance build settings

I had a same problem and I found that under Project-> Build Rules, gcc compiler was being used which no longer exist with Xcode 5.

first, if you use virtual machine, maybe it's the problem when it doesn't have grant to access into your project if not check your file Maybe you miss any file?

I found something similar in an old project I have today. What happened is that there was a subproject in my project and that one wasn't set to llvm5.

You may want to do a search in your directory to find a file specifying llvm 4.2, like such:

MyMac:~/path/to/my/project $ grep -rHin llvm *

MyProject.xcodeproj/project.pbxproj:334: GCC_VERSION = com.apple.compilers.llvmgcc42;
MyProject.xcodeproj/project.pbxproj:348: GCC_VERSION = com.apple.compilers.llvmgcc42;

If that's the case, try updating that subproject or removing it altogether, see if you can at least clean your build.

Hope this helps.
