只是好奇.对于实际编程来说,这显然不是一个很好的解决方案,但是我想在Bless(十六进制编辑器)中创建一个可执行文件.

我的架构是x86.我能制作一个非常简单的程序是什么？你好世界？无限循环？类似于this问题,但在Linux中.

解决方法:

正如我的评论中所提到的,你将基本上为可执行文件编写自己的elf-header,从而消除不需要的部分.仍有几个必修部分. Muppetlabs-TinyPrograms的文档可以很好地解释这个过程.为了好玩,这里有几个例子：

相当于/ bin / true(45字节)：

00000000  7F 45 4C 46 01 00 00 00  00 00 00 00 00 00 49 25  |.ELF..........I%|
00000010  02 00 03 00 1A 00 49 25  1A 00 49 25 04 00 00 00  |......I%..I%....|
00000020  5B 5F F2 AE 40 22 5F FB  CD 80 20 00 01           |[_..@"_... ..|
0000002d

你的经典’Hello World！’ (160字节)：

00000000  7f 45 4c 46 01 01 01 03  00 00 00 00 00 00 00 00  |.ELF............|
00000010  02 00 03 00 01 00 00 00  74 80 04 08 34 00 00 00  |........t...4...|
00000020  00 00 00 00 00 00 00 00  34 00 20 00 02 00 28 00  |........4. ...(.|
00000030  00 00 00 00 01 00 00 00  74 00 00 00 74 80 04 08  |........t...t...|
00000040  74 80 04 08 1f 00 00 00  1f 00 00 00 05 00 00 00  |t...............|
00000050  00 10 00 00 01 00 00 00  93 00 00 00 93 90 04 08  |................|
00000060  93 90 04 08 0d 00 00 00  0d 00 00 00 06 00 00 00  |................|
00000070  00 10 00 00 b8 04 00 00  00 bb 01 00 00 00 b9 93  |................|
00000080  90 04 08 ba 0d 00 00 00  cd 80 b8 01 00 00 00 31  |...............1|
00000090  db cd 80 48 65 6c 6c 6f  20 77 6f 72 6c 64 21 0a  |...Hello world!.|
000000a0

别忘了让它们可执行……
