编译现有的C++代码以在DOS中运行
Compile existing C++ code to run in DOS
我目前在C++中有一个应用程序，可以将一些文件复制到用户的硬盘上。我在闪存驱动器上使用Hiren的BootCD来启动MiniXP并在其下运行我的应用程序，但是加载时间有点慢，因此我想将我的应用程序添加到磁盘附带的DOS映像中。我的问题是该应用程序无法运行，因为"此应用程序无法在DOS模式下运行"。
如何在DOS或任何其他可以从USB驱动器足够快的操作系统下运行此应用程序？
我的应用是一个控制台应用程序，其代码为：
#include <iostream>
#include <fstream>
#include <windows.h>
#include <string.h>
#include <sys/stat.h>
#include <stdio.h>
#include <io.h>
#define MAX 256

bool exists(const std::string& dirName_in)
{
DWORD ftyp = GetFileAttributesA(dirName_in.c_str());
if (ftyp == INVALID_FILE_ATTRIBUTES)
return false; //something is wrong with your path!
if (ftyp & FILE_ATTRIBUTE_DIRECTORY)
return true; // this is a directory!
return false; // this is not a directory!
}
bool fileexists (const std::string& name) {
struct stat buffer;
return (stat (name.c_str(), &buffer) == 0);
}

dr_type=GetDriveType(temp);
switch(dr_type) {

checkdrive(temp);
break;
}
temp += lstrlen(temp) +1; // incriment the buffer

首先，你需要一个可以生成DOS代码的编译器，比如watcom c++http://www.openwatcom.org/index.php/Main_Page：
您的程序使用Windows api调用（它包括windows.h），您需要将所有这些函数替换为它们的DOS等效项或自己编写替代项。
