我跟着http://brandontreb.com/beginning-jailbroken-ios-development-building-and-deployment
做一个调整。
但在我成功完成了helloworld的调整之后
我使用fopen
来挂钩MSHookFunction
然后我遇到链接错误
Making all for tweak hw...
Preprocessing Tweak.xm...
Compiling Tweak.xm...
Linking tweak hw...
Undefined symbols for architecture armv7:
"_MSHookFunction", referenced from:

make[1]: *** [internal-library-all_] Error 2

这是Tweak.xm
#import "substrate.h"
static FILE * (*s_orig_fopen) ( const char * filename, const char * mode );
static FILE * my_fopen ( const char * filename, const char * mode ){
return s_orig_fopen(filename, mode);
}
static void entry(void) __attribute__ ((constructor));
static void entry(void) {
MSHookFunction(fopen, my_fopen, &s_orig_fopen);
}
有谁知道如何修复它?
答案 0 :(得分:0)
你可以试试这个:
#import "substrate.h"
static FILE * (*s_orig_fopen) ( const char * filename, const char * mode );
static FILE * my_fopen ( const char * filename, const char * mode ){
return s_orig_fopen(filename, mode);
}
%ctor {
MSHookFunction(fopen, my_fopen, &s_orig_fopen);
}
