我正在尝试生成一个 PE 格式的可执行文件 - Windows 7，64 位，最初是一个用于测试目的的最小文件，仅执行以下操作

mov eax, 42
ret

我有一个 dumpbin 似乎很满意并且包含所有字段的明显有效值我可以找到的各种来源说实际使用了，但是当我尝试运行它时，Windows 说“不是有效的 Win32 应用程序” . dumpbin 输出如下；谁能从中看出我缺少什么？

  Summary

        1000 .text

最佳答案

您的“图片大小”仅涵盖标题区域； .text 部分和入口点位于其外部。至少将其设置为 1006，文件应该可以工作。

我是怎么找到它的:

1. 制作了一个最小的 C 程序:

   整型条目() { 返回 42；

2. 在没有库和自定义条目的情况下编译它:

   cl test.cpp/link/nodefaultlib/entry:entry/subsystem:console

3. 开始编辑 header 以匹配您的列表，并在每次更改后运行 exe。将 SizeOfImage 更改为 1000 后，我收到“不是有效的 Win32 应用程序”消息。
