如何从 Objective-C 代码中提取 AST? [英] How to extract AST from Objective-C code?

问题描述

我需要分析Objective-C静态代码，主要是AST，在查看可能的工具后发现LLVM的Clang工具可以转储AST，所以我用终端用这个命令测试它:

I need to analyze Objective-C static code, mainly AST, after looking into the possible tools I found out that Clang tool from LLVM can dump the AST, so I used the terminal to test it using this command:

clang -cc1 -ast-dump ~/SomeTest.m

但我收到此错误:

In file included from /Users/myusername/SomeTest.m:9:
/Users/myusername/SomeTest.h:9:9: fatal error: 'UIKit/UIKit.h' file not found
#import <UIKit/UIKit.h>

struct __va_list_tag {
    unsigned int gp_offset;
    unsigned int fp_offset;
    void *overflow_arg_area;
    void *reg_save_area;
};
typedef struct __va_list_tag __va_list_tag;
typedef __va_list_tag __builtin_va_list[1];

@end

知道为什么我会得到这个吗?我不介意使用任何工具从 Objective-C 代码中提取 AST，只要它可靠并提供输出文档

Any idea why I'm getting this? I don't mind using any tool to extract AST from Objective-C code as long as it is reliable and provide documentation for the output

推荐答案

编译器没有找到 UIKit 框架.你必须告诉它使用它:

The compiler does not find the UIKit framework. You have to tell it to use it:

clang -framework UIKit -cc1 -ast-dump ~/SomeTest.m
