我已经问过类似的问题,"PE Header requirements" ,但我对它的答案并不满意。
我正在用 Java SE 1.6 构建一个汇编器/链接器。我已经阅读了大约 5 个关于 PE/COFF header 和文件格式的不同文档/规范,但我遇到了一个问题:
我生成的文件无效,Windows 说: “X 不是有效的 Win32 应用程序。” 我不知道什么是错的;我已经仔细检查了 PE Header 和 PE Optional Header 中的每个条目,一切似乎都是正确的。
我有三个部分:
code
(RVA 0x1000
,文件 0x400
)data
(RVA 0x2000
,文件 0x600
)import
(RVA 0x3000
,文件 0x800
)我的入口点值为
0x1000
( code
的开头),我的图像库是 0x400000
.部分对齐方式为 0x1000
和文件对齐是 0x200
.查看此问题的修订以查看整个文件。
所以:我获取了一个有效的 PE 文件(一个简单的“Hello World”消息框应用程序),并开始使用十六进制编辑器 (HxD) 对其进行修改。我收到了很多不同的错误消息,而不是“X 不是有效的 Win32 应用程序。”:
我知道我的
code
content 不是“有效”代码,但我已经对其进行了测试:无效代码会导致应用程序崩溃错误。如果“Hello World”PE 文件中的导入部分内容无效,则会出现错误“在 [...] 中找不到过程点”或“应用程序无法启动,因为 [..] dll 是未找到。”,或应用程序崩溃。这些错误都非常有用;他们都给了我一些线索,出了什么问题。
但是我的 PE 文件出现错误“X 不是有效的 Win32 应用程序。”,让我发疯:我的 PE 文件有什么问题?

最佳答案
你肯定是从错误的一端解决这个问题的。破解十六进制永远不会得到你想要的东西,PE 文件结构太复杂了。你需要两件事。
编写代码以根据它们的声明创建结构,这是获得有效可执行文件的唯一方法。
PS:您的十六进制转储挂断了任何试图查看您的问题的人的浏览器。
