创建编译器的一个简单方法是使用bison和flex(或类似)，构建一个树(AST)并用C生成代码，生成C代码是最重要的步骤。通过生成C代码，您的语言将自动在所有具有C编译器的平台上运行。

生成C代码就像生成HTML一样简单(只需使用打印或等效工具)，这又比编写C解析器或HTML解析器容易得多。

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.

看看下面这本书。作者是ANTLR的创建者。

语言实现模式:创建您自己的领域特定语言和通用编程语言。

如果你像我一样，没有受过正规的计算机科学教育，并且对 构建/想知道编译器是如何工作的:

我推荐“Java编程语言处理器:编译器和解释器”， 对于自学成才的计算机程序员来说，这是一本令人惊叹的书。

在我看来，理解那些基本的语言理论、自动化机器和集合理论并不是什么大问题。问题是如何把这些东西转换成代码。上面的书告诉您如何编写解析器、分析上下文和生成代码。如果你不能理解这本书，那么我不得不说，放弃构建编译器吧。这本书是我读过的最好的编程书。

还有一本书，也很好，《c语言编译器设计》，里面有很多代码，告诉你如何构建编译器和词法分析器工具。

构建编译器是一种有趣的编程实践，可以教会您许多编程技能。

不要买龙的书。这是浪费金钱和时间，不适合从业者。

如果你想使用功能强大的高级工具，而不是自己构建一切，那么阅读本课程的项目和阅读材料是一个很好的选择。这是一门语言课程，由Java解析器引擎ANTLR的作者编写。你可以从Pragmatic Programmers网站上获得这门课程的PDF版本。

The course goes over the standard compiler compiler stuff that you'd see elsewhere: parsing, types and type checking, polymorphism, symbol tables, and code generation. Pretty much the only thing that isn't covered is optimizations. The final project is a program that compiles a subset of C. Because you use tools like ANTLR and LLVM, it's feasible to write the entire compiler in a single day (I have an existence proof of this, though I do mean ~24 hours). It's heavy on practical engineering using modern tools, a bit lighter on theory.

顺便说一下，LLVM非常棒。在许多情况下，你可能会编译到汇编，你最好编译到LLVM的中间表示。它是更高级别的、跨平台的，LLVM非常擅长从中生成优化的程序集。

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》。
