A Whirlwind Tutorial on Creating Really Teensy ELF Executables for Linux
A Whirlwind Tutorial on Creating Really Teensy ELF Executables for Linux She studied it carefully for about 15 minutes. Finally, she spoke. "There's something written on here," she said, frowning, "but it's really teensy." [Dave Barry, "The Columnist's Caper"] If you're a programmer who's become fed up with software bloat, then may you find herein the perfect antidote. This document explores metho

最小限のELF | κeenのHappy Hacκing Blog
κeenです。 先日の記事で言及した最小限のELFが需要ありそうだったので解説してみます。 コンパイラを作るときの参考にしてみて下さい ELFはExecutable and Linkable Formatを表わし、Linuxなどで標準の実行可能ファイルのフォーマットとなっています。 なんらかの形でこのファイルを生成するのがコンパイラの最終目標となります。 一般にはアセンブラまで吐いて外部のアセンブラやリンカにELFファイルの生成を任せることが多いのですが、自作するなら最後までやりたいという人向けにとっかかりになる最小限のELFファイルを解説します。 まずはこのファイルを生成するのを目指して、後から色々追加していけばインクリメンタルにできるよね、という訳です。 一部、「どうしてかは分からないけどこうしたら動く」みたいな箇所もあるので詳しい人がいたら教えて下さい。 全体構成 プログラムそのもの
The 101 of ELF files on Linux: Understanding and Analysis - Linux...
Some of the true craftsmanship in the world we take for granted. One of these things is the common tools on Linux, like ps and ls. Even though the commands might be perceived as simple, there is more to it when looking under the hood. This is where ELF or the Executable and Linkable Format comes in. A file format that used a lot, yet truly understood by only a few. Let’s get this understanding wit

Negrebskoh.net - HOWTOs
Go back Hello class, and welcome to X86 Masochism 101. Here, you'll learn how to use opcodes directly to create an executable without ever actually touching a compiler, assembler or linker. We'll be using only an editor capable of modifying binary files (i.e. a hex editor) and 'chmod' to make the file executable.[1] If that doesn't turn you on, I don't know what will. On a more serious note, this
