Question

在我2010年视觉演播室,有2个项目。一种是静态的校准(如果有人问的话,为2.3),另一种是DL。两者均将汇编成一份/MT文件。

mhook project has two functions in its mhook.h:

BOOL Mhook_SetHook(PVOID *ppSystemFunction, PVOID pHookFunction);
BOOL Mhook_Unhook(PVOID *ppHookedFunction);

dll项目参考了红.项目,并利用Mhook_SetHook和Mhook_Unhook。使用了Same mhook.h。当我汇编粉碎项目时,我有以下错误:

1>hookdll.obj : error LNK2001: unresolved external symbol _Mhook_Unhook

请注意,链接成功发现Mhook_SetHook。如果我评论Mhook_Unhook的使用情况,该方案将成功地汇编成册。

Dumpbin建议,两个标志都存在于静态图书馆:

>dumpbin /symbols mhook-test.lib|find "Mhook"
015 00000000 SECT4  notype ()    External     | ?Mhook_SetHook@@YAHPAPAXPAX@Z (i
nt __cdecl Mhook_SetHook(void * *,void *))
122 00000000 SECT3B notype ()    External     | ?Mhook_Unhook@@YAHPAPAX@Z (int _
_cdecl Mhook_Unhook(void * *))
>

我丢失和混淆,请帮助。

Answer 1

Answer: I was apparently mixing C++ and C code - the library at hand was in C++ and my program in C.

我不得不在周围添加外围的C,从Using C++ Library in Ccode:

#ifdef __cplusplus
extern "C" {
#endif
BOOL Mhook_SetHook(PVOID *ppSystemFunction, PVOID pHookFunction);
BOOL Mhook_Unhook(PVOID *ppHookedFunction);
#ifdef __cplusplus
} // extern "C"
#endif

一旦我这样做,我的象征出口开始看好:
