推荐答案
嗯，我没有谷歌，但是使用工具lex编写编译器的最好方法是使用工具。
和yacc （或者也称为 - 与某些
差异 - flex和bison），第一个是词法分析器
（扫描仪词法分析器），第二个是解析器。
我相信你可以在网上找到大部分信息，但是如果你真的想要了解b $ b想要学习这个东西，我建议你买龙书，
，正式命名为编译器，原理，技术和工具
by Aho，Sethi和Ullman，这是该领域的事实上的书。
Well, I did not google it, but the best way to write a compiler is
using the tools, "lex" and "yacc" (or also known as - with some
differences - "flex" and "bison"), the first one is a lexer
(scanner-lexical analyzer), and the second one is a parser.
I am sure you can find most of the info in the web, but if you really
want to learn this stuff, I would suggest you to buy the "Dragon Book",
which is formally named "Compilers, Principles, Techniques, and Tools"
by Aho, Sethi and Ullman, this is the de-facto book in the field.

我认为你没有密切关注这个新闻组。如果你有
，你现在就知道，假设每个人都可以看到你回复的那篇文章是不安全的，那你就是需要
提供一些上下文。
如果你想通过groups.google.com发布一个后续，不要使用
破损的回复链接在文章的底部。点击
" show options"在文章的顶部，然后点击
回复在文章标题的底部。
请向谷歌抱怨他们的界面坏了。
至于原始问题，解析C由于typedef问题，结果很难实现。 typedef名称在词法上是一个标识符，但它的作用类似于保留字 - 但仅限于定义它的
作用域。这意味着你的解析器无法在没有符号表反馈的情况下分析
代码。
一旦你解决了这个问题，你就得到了仍然只完成了实现编译器所需的工作的一小部分。你应该问问自己是否真的值得付出努力，因为它已经是一些免费软件了。我绝对不会说你不应该这样做，
只是这将是一项很大的工作。
还有一个comp.compilers新闻组（您应该在发布之前浏览
a，如果有的话，请阅读常见问题解答）。

我们必须做点什么。这是事情。因此，我们必须这样做。
I take it you haven''t been following this newsgroup closely. If you
had, you would know by now that it''s unsafe to assume that everyone
can see the article to which you''re replying, and that you need to
provide some context.
If you want to post a followup via groups.google.com, don''t use
the broken "Reply" link at the bottom of the article. Click on
"show options" at the top of the article, then click on the
"Reply" at the bottom of the article headers.
And please complain to Google about their broken interface.
As for the original question, parsing C turns out to be fairly
difficult because of the typedef problem. A typedef name is lexically
an identifier, but it acts like a reserved word -- but only in the
scope where it''s defined. That means your parser can''t analyze the
code without feedback from the symbol table.
Once you''ve solved this, you''ve still done only a fraction of the work
necessary to implement a compiler. You should ask yourself whether
it''s really worth the effort, given that ther are a number of freeware
C compilers already. I''m not by any means saying you shouldn''t do it,
just that it''s going to be a lot of work.
There''s also a "comp.compilers" newsgroup (which you should browse for
a while before posting, and read the FAQ if they have one).

We must do something. This is something. Therefore, we must do this.
