“make: yacc: Command not found” after installing Bison

Question

While running a makefile in gcc 4.1.2 (linux 5), I got the following error

make: yacc: Command not found

By googling, I came to know that this

Answer 1

From the looks of things, your makefile is expecting a yacc executable to be available and either it's not, or it's not on your path.

Since bison is supposed to be compatible with yacc so the first thing I would try would be:

alias yacc="bison"

and try again. On my setup, /usr/bin/yacc is simply a script containing:

#! /bin/sh
exec '/usr/bin/bison' -y "$@"

You can try to locate the yacc or bison executables with the command (substituting bison for yacc if need be):

which yacc

But they're probably in one of the standard places like /bin or /usr/bin.
