What way are you trying to compile it i use automake, but if your
doing it manualy. I always found i have to compile it something like this:

gcc -o myparserprogramm y.tab.c lex.yy.c -ll

In the one line but its too hard to tell where to help unless you post
a little more of what your doing.

If your definiing a union that means in your flex you can use
yylval.<union element> and in your parser you need to use

%token <union element name>mytoken

Anyways i dont know if this helps but hey
