这里是源代码的zip文件:http: //cfile218.uf.daum.net/attach/254F2D4F5211EF93107910
,或底部可见的源代码。
我刚刚在我的 PC 上编译并运行它:在调试和发布模式下都运行良好。
但是,如果我尝试在另一台 PC 上运行它(安装了 Windows XP),它会显示一个错误,指出我没有“jvm.dll”,因此无法运行它。
因此我从地址“ http://java.com/en/download/index.jsp ”安装了java并运行了它。但是,它仍然说同样的错误。
是我的问题......
如何让它在没有 JDK 或 MSVC 的其他普通 PC 上运行?因为普通用户肯定没有JDK ..
