Where do i download lex and yacc for linux?

And how do i intall them?

Both lex and yacc should be part of one of your development toolchains.

How to get them depends entirely on your distro.

For example, in Ubuntu, you would kick up Synaptic and search for, hmmm, let me think, ..., yes, that's it, "lex" or "yacc" - I knew it would come to me :-)

Sorry, got a little carried away there. Actually, you're more likely to have luck looking for flex and bison. The bison program is the GNU version which is upward compatible with yacc, and flex, while not GNU, is still free (both speech-free and beer-free).

I don't have much recent experience with Linux but back when I was doing some compiler development on Irix we used Flex and Bison. Those are, as far as I remember, more modern versions of Lex and Yacc, and may be easier to find for your distro.
