PE 文件 - 缺少什么? [英] PE file - what's missing?

问题描述

我正在尝试生成 PE 格式的可执行文件 - Windows 7，64 位，最初是用于测试目的的最小文件，仅用于

I'm trying to generate an executable in PE format - Windows 7, 64 bit, initially a minimal file for testing purposes that does nothing more than

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过，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；谁能从中看出我错过了什么?

I've got one that dumpbin seems happy with and contains apparently valid values for all the fields the various sources I can find say are actually used, but when I try to run it, Windows says 'not a valid Win32 application'. dumpbin output follows; can anyone see from this what I'm missing?

  Summary

        1000 .text

推荐答案

您的图像大小"仅包含标题区域；.text 部分和入口点位于它之外.将其设置为至少 1006，该文件应该可以工作.

Your "size of image" covers only the header area; the .text section and the entry point lies outside of it. Set it to at least 1006 and the file should work.

我是如何找到它的:

1. 制作了一个最小的 C 程序:

1. Made a minimal C program:

int entry(){返回 42；}

int entry() { return 42; }

在没有库和自定义条目的情况下编译它:

Compiled it without libraries and with custom entry:

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

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

开始编辑标题以匹配您的列表，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.

Started editing the header to match your listing, and run the exe after each change. Once I changed the SizeOfImage to 1000, I got the "not a valid Win32 application" message.
