Where to get Yacc?
 

Hi I'm having a problem installing portion of package 'Omni-1.6.tar'
which is a free openMPI c compiler. It asked for yacc, but as I have read in various website, bison is the modern port of the yacc. I've tried finding for yacc/lex all over the internet. But suprisingly there's not even one available, anywhere. And from the way I observed, yacc looks luike it's obsolete or not free at all, no?

During the 'make' stage of Omni, it wrote yacc: command not found.

I hope at least someone can point me where to download yacc.

Secondly, hope someone can clarify me about bison being a port of yacc, and if it's true, can I actually do something to make bison act as yacc, or something like that. My head is spinning :P

P.S: Tried to install an openMPI environment over linux, I'm using i386 architecture which is AMD Athlon XP 2000 trhoughbred. Somehow I can't get it running, been trying to install odinMP before this.

You're right. You have to install bison. It will create a script named "yacc" which in fact runs bison with the "--y" option to act like yacc.

On some distros the package is byacc.
