XCode Static Analyzer: Analyzer skipped this file due to parse errors

Question

I have been able to run the Static Analyzer on my code fine for months. All of a sudden now I am getting the error:

<command line>:0:0 Analyzer skipped this file due to parse errors

Not sure how to diagnose.

The first tile it skips is:

/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.1.sdk/System/Library/Frameworks/CoreGraphics.framework/Headers/CGPDFContext.h:0:0 Analyzer skipped this file due to parse errors

Answer 1

如果我在目标设置为模拟器时尝试使用它，我也会收到这些错误，但是如果我将目标切换到设备那么它就可以工作了。

Answer 2

Typically, this is a result of a syntax error or something else that is preventing your code from compiling.

Because you are only seeing errors when you go to analyze your code, not when it compiles, I bet that you are using the GCC compiler for your main application builds. Clang / LLVM has a bug in the iOS 4.1 SDK that causes compilation errors when targeting the Simulator, but not the device. The Clang Static Analyzer is probably exhibiting this same bug.

The solution I provide in my answer to the above-linked question should work to fix this as well. However, it may lead to compilation errors when you switch back to build your application with GCC, so I recommend switching your compiler over to LLVM. Unless you are using C++ code, I recommend using LLVM for iPhone projects anyway, due to the minor performance boosts you can get in your compiled application with it.
