我已经问过类似的问题,
"PE Header requirements"
,但我不太满意这个答案。
我在JavaSE 1.6中构建了一个汇编器/链接器。我已经阅读了关于pe/coff头和文件格式的5个不同的文档/规范,但是我遇到了一个问题:
我生成的文件无效,Windows说:
“x不是有效的win32应用程序。”
我不知道什么是错误的;我已经仔细检查了pe头和pe可选头中的每个条目,所有的似乎都是正确的。
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
(开始
代码
)我的图像库是
0x400000
. 断面线形为
0x1000
文件对齐是
0x200
.
请参阅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),并使用hex编辑器(hxd)开始修改它。我收到了很多不同的错误信息,
不
“x不是有效的win32应用程序。”:
我知道
代码
内容不是“有效”代码,但我已经测试过了:无效代码会导致应用程序崩溃错误。
如果“hello world”pe文件中的导入节内容无效,则会出现错误“在[…]中找不到过程点”,或“由于找不到[…]dll,应用程序无法启动”,或应用程序崩溃。这些错误都是非常有用的,它们都给了我一些错误的线索。
但是我的pe文件,错误是“x不是有效的win32应用程序。”,让我疯狂:
我的体育档案怎么了?
