"make:yacc:找不到命令"；在安装Bison之后 [英] "make: yacc: Command not found" after installing Bison

问题描述

在gcc 4.1.2(linux 5)中运行makefile时，出现以下错误

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

make: yacc: Command not found

通过谷歌搜索，我知道可以通过安装Bison-GNU解析器生成器来纠正此错误. 但是即使安装了Bison，我仍然遇到相同的错误.

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.

该错误如何解决?

推荐答案

从外观上看，您的makefile期望yacc可执行文件可用，或者它不存在，或者不在您的路径上.

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.

由于bison应该与yacc兼容，所以我首先要尝试的是:

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

alias yacc="bison"

，然后重试.在我的设置中，/usr/bin/yacc只是一个包含以下内容的脚本:

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

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

您可以尝试使用以下命令找到yacc或bison可执行文件(如果需要，将bison替换为yacc):

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

which yacc

但是它们可能位于/bin或/usr/bin等标准位置之一.

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