Lua中無法加載VC++ DLL

我編我的litertools使用Visual Studio C/C++工具鏈項目作爲一個.dll並正確導出lua_openlitertools功能：Lua中無法加載VC++ DLL

PS> dumpbin /exports .\bin\lib\litertools.dll 
Microsoft (R) COFF/PE Dumper Version 14.00.22013.1 

Dump of file .\bin\lib\litertools.dll  

    Section contains the following exports for litertools.dll

當我設置配置package.cpath和然後通過執行要求litertools DLL：

CMD> lua -e "package.cpath=\".\\bin\\lib\\?.dll\"; require(\"litertools\")"

我收到以下錯誤

lua: error loading module 'litertools' from file '.\bin\lib\litertools.dll': 
     The specified module could not be found. 

stack traceback: 
     [C]: in ? 
     [C]: in function 'require' 
     (command line):1: in main chunk 
     [C]: in ?

尋找到它，我調試通過電話要求（loadlib.c），並得到了到這裏：

static void *ll_load (lua_State *L, const char *path, int seeglb) { 
    HMODULE lib = LoadLibraryExA(path, NULL, LUA_LLE_FLAGS); 
    (void)(seeglb); /* not used: symbols are 'global' by default */ 
    if (lib == NULL) pusherror(L); 
    return lib; 
}

的調用LoadLibraryExA回報NULL。我不確定爲什麼發生這種情況，儘管我已經使用mingw-gcc編譯了相同的庫並且能夠要求dll。
