Xcode cannot run using the selected device after upgrade to Xcode 5.0
It appears that the problem is not related to the architecture in the build settings as the error might suggest. Rather, I found that the problem seems to be related to the Build Options Compiler for C/C++/Objective C. I was using a gcc compiler (com.apple.compilers.llvmgcc42) and Xcode 5 has marked this as unsupported.
If I change the compiler to apple's default Apple LLVM 5.0, the project builds and it can now run in the simulator. The downside is that I have a lot of compiler warnings from code related to cocos2D v1.0 source code. But, at least I have a way forward.
Please follow below step
1>Go to Project Build setting
2>Change compiler for c/c++/objective c as Default compiler(Apple LLVM 5.0) (see in below image)
I had to change compiler for Default compiler (Apple LLVM 5.0) at two places:
- Build Settings > Build Options > Compiler for C/C++/Objective-C (change to LLVM)
- Build Rules > Files *.mc using GCC (change to LLVM)
Hard to find because code compiles even if Build Rules point to an undefined compiler.
