[David Ja]

Hi,
 My name is David Ja, an undergraduate student at university of 
pennsylvania. I am attempting to start a minor research project myself. I 
been trying to adapted bison to my own purpose but after a month of trying I 
can't seem to figure out a way to make it work. All I wanted to do was to 
take advantage of bison's parser which generates the DFA, which in turn, 
allows me to step through the DFA in sequence generating a sample string 
that fits the grammar input. For example if the grammar is the grammar for 
an web address. My program will be able to generate
http://www.abc.org<http://www.abc.org>.
I have attached my "attempt" code with this email. The problem I arrive at 
is I don't seem to be able to compile it with bison code. For some reason, 
even if I leave it in the same folder as bison src, I still arrive at a 
deference to pointer error. I'm sorry if I made an elementary mistake or 
something stupid. Thank you for any help/suggestions you can give me. It is 
also possible I'm not taking advantage of bison data structure the right 
way. If so I am sorry if I wasted any of your time. This is my first attempt 
at understand the inner working of a program of this magnitude. If I am not 
being clear about something or if I email the wrong place. I am extremely 
sorry. Again thank you very much for any help you can give me. 
 Best,
David
