The dragon book almost convinced me never to try to write a compiler. I don't know why people recommend it. I guess you're a lot smarter than I am.
There are some excellent books out there. In its own way, the dragon book is excellent, but it is a terrible starting place.
Here are a bunch of references from the same vintage as OP. I recommend starting with a book that actually walks through the process of building a compiler and doesn't spend its time exclusively with theory.
I started with the dragon book, and I found it to be a good introductory text.
A lot of people say the dragon book is difficult, so I suppose there must be something there. But I don't see what it is, I thought it was quite accessible.
I'm curious, what parts/aspects of the dragon book make it difficult to start with?
