难道说是LuaPlus不支持多线程程序吗

难道是LuaPlus不支持多线程程序吗?我成功编译了LuaPlus5.01,写了一个简单的lua文件——TestLua.lua:health

难道是LuaPlus不支持多线程程序吗?
我成功编译了LuaPlus5.01,写了一个简单的lua文件——TestLua.lua:

health = 200; 



然后编了一个控制台程序来测试它,代码如下:

C/C++ code
#include <stdlib.h>#include <windows.h>#include <tchar.h>#include <iostream>using namespace std;#include <string>#include "../LuaPlus/LuaPlus.h"using namespace LuaPlus;int main(){        TCHAR szModulePath[_MAX_PATH];    ::GetModuleFileName(NULL,szModulePath,_MAX_PATH);    std::string strBinPath = szModulePath;    strBinPath = strBinPath.substr(0,strBinPath.rfind('\\')+1);    std::string LusFilePath = strBinPath + std::string(_T("TestLua.lua"));    LuaStateOwner state;    // 执行Lua脚本,返回值表示执行成功    int iret = state->DoFile(LusFilePath.c_str());    if (0!=iret)    {        return 1;    }    // 获取生命值    int nMyHealth = state->GetGlobal("health").GetInteger();    cout<<_T("玩家的生命值还有")<<nMyHealth<<std::endl;    system("pause");    return 0;}


  然后可以成功测试通过。接着我写了一个Win32 GUI程序,代码大致如下(这里主要是WinMain函数的代码):

C/C++ code
#include <windows.h>#include <tchar.h>using namespace std;#include <string>#include "../LuaPlus/LuaPlus.h"using namespace LuaPlus;/*  Declare Windows procedure  */LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);/*  Make the class name into a global variable  */char szClassName[ ] = "CodeBlocksWindowsApp";int WINAPI WinMain (HINSTANCE hThisInstance,                     HINSTANCE hPrevInstance,                     LPSTR lpszArgument,                     int nCmdShow){    TCHAR szModulePath[_MAX_PATH];    ::GetModuleFileName(NULL,szModulePath,_MAX_PATH);    std::string strBinPath = szModulePath;    strBinPath = strBinPath.substr(0,strBinPath.rfind('\\')+1);    std::string LusFilePath = strBinPath + std::string(_T("TestLua.lua"));    LuaStateOwner state;    // 执行Lua脚本,返回值表示执行成功    int iret = state->DoFile(LusFilePath.c_str());    if (0!=iret)    {        return 1;    }    // 获取生命值    int nMyHealth = state->GetGlobal("health").GetInteger();    HWND hwnd;               /* This is the handle for our window */    MSG messages;            /* Here messages to the application are saved */    WNDCLASSEX wincl;        /* Data structure for the windowclass */    /* The Window structure */    wincl.hInstance = hThisInstance;    wincl.lpszClassName = szClassName;    wincl.lpfnWndProc = WindowProcedure;      /* This function is called by windows */    wincl.style = CS_DBLCLKS;                 /* Catch double-clicks */    wincl.cbSize = sizeof (WNDCLASSEX);    /* Use default icon and mouse-pointer */    wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);    wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);    wincl.hCursor = LoadCursor (NULL, IDC_ARROW);    wincl.lpszMenuName = NULL;                 /* No menu */    wincl.cbClsExtra = 0;                      /* No extra bytes after the window class */    wincl.cbWndExtra = 0;                      /* structure or the window instance */    /* Use Windows's default colour as the background of the window */    wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;    /* Register the window class, and if it fails quit the program */    if (!RegisterClassEx (&wincl))        return 0;    /* The class is registered, let's create the program*/    hwnd = CreateWindowEx (           0,                   /* Extended possibilites for variation */           szClassName,         /* Classname */           "Code::Blocks Template Windows App",       /* Title Text */           WS_OVERLAPPEDWINDOW, /* default window */           CW_USEDEFAULT,       /* Windows decides the position */           CW_USEDEFAULT,       /* where the window ends up on the screen */           544,                 /* The programs width */           375,                 /* and height in pixels */           HWND_DESKTOP,        /* The window is a child-window to desktop */           NULL,                /* No menu */           hThisInstance,       /* Program Instance handler */           NULL                 /* No Window Creation data */           );    /* Make the window visible on the screen */    ShowWindow (hwnd, nCmdShow);    /* Run the message loop. It will run until GetMessage() returns 0 */    while (GetMessage (&messages, NULL, 0, 0))    {        /* Translate virtual-key messages into character messages */        TranslateMessage(&messages);        /* Send message to WindowProcedure */        DispatchMessage(&messages);    }    /* The program return-value is 0 - The value that PostQuitMessage() gave */    return messages.wParam;}/*  This function is called by the Windows function DispatchMessage()  */LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam){    switch (message)                  /* handle the messages */    {        case WM_DESTROY:            PostQuitMessage (0);       /* send a WM_QUIT to the message queue */            break;        default:                      /* for messages that we don't deal with */            return DefWindowProc (hwnd, message, wParam, lParam);    }    return 0;} 




  结果程序可以编译链接成功,但运行不起来。在调试运行时无法进入WinMain函数,只出现下面的Lua命令行界面:



  难道是LuaPlus不支持多线程程序吗?

  我的编译环境是:

Win 7家庭版,CodeBlocks V10.05, mingw32 v4.4.1


   


[解决办法]
没看你的代码.
不过lua本身是不支持多线程的.所以,要想在多线程环境下用lua就必须自己处理线程的问题.不知道你用的库有没有这方面的考虑.按理说,它应该不会考虑这个问题.因为加入多线程的支持对lua行为会有一些影响.会显得比较不"兼容"
