问题
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 error can be rectified by installing Bison-GNU parser generator. But even after installing Bison, I get the same error.
How can this error be solved?
回答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.
回答2:
Run the following command on your terminal to install bison, yacc executables and configurations.yacc comes along with bison
Also you need byacc for a full functional yacc
sudo apt-get install bison -y
sudo apt-get install byacc -y
It worked for me.

I ran into a similar issue on RHEL7.
Find where bison is:
$:which bison
*/bin/bison*
Create symlink to bison from yacc:
sudo ln -s /bin/bison /bin/yacc
And that should solve the problem.
回答4:
I created the alias file on my Ubuntu 16 system, while testing then I found that bison was missing so I installed bison which gave me an error about the link that I had made for /usr/bin/yacc, so the bison install creates the lnk file itself for yacc on Ubuntu 16.
