hi , i am doing project on designing C Compiler in linux.
can I get yacc grammars for designing C Compiler and its lex specification.......

also I want code of C Compiler which can compile C programs...

Hey, you probably need the dragon book set about compiler design.

First, welcome to LQ!

Try these to start with:
1. http://www.ibm.com/developerworks/li...l?dwzone=linux
And check the link section on the *left* side

2. http://epaperpress.com/lexandyacc/
3. http://www.angelfire.com/dragon/lets...ler/index.html

Note: And one more thing, you'd get better response by posting in the proper forum. I guess this should go in "Linux - Programming" and please avoid reposting (I'm telling you before a Mod does that

).

Go look at a compiler. There are lots of them out there, some student-oriented and some (like gcc itself) purely oriented toward professional use.

To me, "an example is worth a thousand books."

I think there were ample references. You should now do you homework

Read the dragon book, and look, maybe, at GCC. Not sure if it contains a yacc parser.

Which work did you do before? It is quite uncommon to start with a beast as complex as a full C grammar...
