PE文件 - 缺少什么?

标签: windows portable-executable

我正在尝试以PE格式生成可执行文件 - Windows 7,64位,最初是用于测试目的的最小文件,只执行

mov eax, 42
ret

我有一个dumpbin看起来很满意并且包含我可以找到的各种来源实际使用的所有字段的显然有效值,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;任何人都可以从中看到我所缺少的东西吗?

答案 0 :(得分:4)

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。将它设置为至少1006,文件应该可以工作。


我是如何找到的:

  1. 制作了一个最小的C程序:

    int entry() {   返回42; }

  2. 编译它没有库和自定义条目:

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

  3. 开始编辑标题以匹配您的商家信息,并在每次更改后运行exe。一旦我将SizeOfImage更改为1000,我就得到了“不是有效的Win32应用程序”消息。

我无法通过查看您的dumpbin输出来判断,但是有一个很好的实用工具,CFF Explorer可用于检查PE文件的几乎所有细节。它是交互式的并显示各种表格,您还可以动态编辑大部分值来试验它。

我发现过去比较容易将值与CFF资源管理器中的PE规范进行比较,而不是使用dumpbin。
