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

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。
