为架构'armv7'选择了不支持的编译器'GCC 4.2'

Question

Just installed new version XCode 4.2 onto my Mac. I tried compiling my project but got the following error:

Unsupported compiler 'GCC 4.2' selected for architecture 'armv7'

Tried selecting arm7 in drop down for architechture in project and target settings. (The list actually shows just arm 7) still no use.

Please help.

Thanks

Answer 1

你应该实际选择“编译器版本”下的LLVM编译器，而不是试图设置“有效的架构”

Answer 2

xcode build errors:

Unsupported compiler ‘GCC 4.2′ selected for architecture ‘i386′

Solution:

This can be caused by importing a project for a pre- iOS 5 SDK into a copy of xcode with iOS 5 SDK only.

To fix, click your

Project -> Build Settings.  

Then under Build Options, there is an entry for Compiler for C/C++/Objective-C. Choose Apple LLVM compiler 3.0.

There is a chance this could effect other aspects of your binaries as you are using a new compiler, so YMMV. That being said, it's so far caused no issues for me.

Answer 3

If you have multiple projects included within a single xCode project, go to editor>Validate project settings . This will set the compiler to LLVM 5.0 even if you don't see that option normally

Answer 4

转到BuildSettings-> BuildOptions-> CompilerFor c / c ++ / Objective C并从'Unsupported Compiler GCC4.2'更改为LLVM GCC 4.2
