Speak for yourself. On my system, yacc is byacc. Bison is too legally
encumbered for me to use comfortably. So i use byacc. I don't think it
needs a library though. I'd have to check to be sure, it's been a while
since i've used it, i usually go with PCCTS these days.

I am trying to compile my yacc program using gcc with the -ly library,
but I keep getting complier error:
/usr/i486-linux/bin/ld: cannot open -ly: No such file or directory

Does anyone know where the library is, or how I can link it to the path?
I am using slackware and have version 2.0.0.

thanks,
adam

On Linux, yacc is actually bison. It doesn't need a library.

On a similer note I kept getting a link error about yywrap. Very annoying I
thought I might need a new bison but that did not help. I finally just
added a yywrap function to my programs. That fixed the error but it is
annoying...

Is there a better answer for this?

This error isn't from bison, it is from flex (aka lex). You must
either link "libfl.a", supply your own yywrap(), or use "%option
noyywrap" in your lexer definition. The scanner calls yywrap() on
EOF. Yywrap() can either point yyin to a new file and return false
to continue scanning from the new file, or it can return true to
indicate no more files. Using "noyywrap" is the same as yywrap()
always returning true.

See "man flex" for more information.
