The Dragon Book is too complicated. So ignore it as a starting point. It is good and makes you think a lot once you already have a starting point, but for starters, perhaps you should simply try to write an math/logical expression evaluator using RD, LL or LR parsing techniques with everything (lexing/parsing) written by hand in perhaps C/Java. This is interesting in itself and gives you an idea of the problems involved in a compiler. Then you can jump in to your own DSL using some scripting language (since processing text is usually easier in these) and like someone said, generate code in either the scripting language itself or C. You should probably use flex/bison/antlr etc to do the lexing/parsing if you are going to do it in c/java.

我发现Dragon的书太难读了，因为它太专注于语言理论，而实际上编写编译器并不需要这些理论。

我将添加Oberon书籍，其中包含了一个惊人的快速和简单的Oberon编译器项目Oberon的完整源代码。

你应该看看Darius Bacon的“ichbins”，这是一个针对小Lisp方言的编译器，目标是C，只有6页多的代码。与大多数玩具编译器相比，它的优势在于该语言足够完整，可以用它来编写编译器。(tarball还包括一个解释器来引导这个东西。)

在我的Ur-Scheme网页上有更多关于学习编写编译器的有用内容。

最快的方法是读两本书:

JP Bennett的1990版《编译技术介绍，使用ANSI C, LeX和YaCC的第一课程》-示例代码，解析理论和设计的完美平衡-它包含了一个用C, LeX和YaCC编写的简单语法的完整编译器

龙书(旧版本)-主要是一个详细的参考功能没有涵盖在前一本书

如果你没有时间，我推荐Niklaus Wirth的“编译器构造”(Addison-Wesley)。1996年)，一本你一天就能读完的小册子，但它解释了基础知识(包括如何实现词法分析器、递归下降解析器和你自己的基于堆栈的虚拟机)。在那之后，如果你想深入了解，就像其他评论者建议的那样，没有办法绕过龙的书。

我同意龙书的参考;IMO，它是编译器构造的权威指南。准备好接受一些核心理论吧。

If you want a book that is lighter on theory, Game Scripting Mastery might be a better book for you. If you are a total newbie at compiler theory, it provides a gentler introduction. It doesn't cover more practical parsing methods (opting for non-predictive recursive descent without discussing LL or LR parsing), and as I recall, it doesn't even discuss any sort of optimization theory. Plus, instead of compiling to machine code, it compiles to a bytecode that is supposed to run on a VM that you also write.

这仍然是一本不错的读物，尤其是如果你能在亚马逊上以便宜的价格买到的话。如果你只想简单介绍编译器，《Game Scripting Mastery》是个不错的选择。如果你想先玩硬核游戏，那么你应该选择《龙之书》。
