为什么我的Mac(OS X 10.7.3)具有旧版本(2.3)的Gnu Bison? [英] Why does my Mac (OS X 10.7.3) have an old version (2.3) of Gnu Bison?

问题描述

我的Mac上的GNU Bison版本是2.3，但我知道Bison 2.5早就发布了.这本书 Flex& Bison 使用2.5版.

The version of GNU Bison on my mac is 2.3 but I know that Bison 2.5 was released long ago. The book Flex & Bison uses version 2.5.

我应该自己升级到2.5吗?有必要吗?

Should I upgrade to 2.5 myself? Is it necessary?

2.3和2.5有什么区别?

What's the difference between 2.3 and 2.5?

推荐答案

如果使用Brew:

brew tap homebrew/dupes && brew install bison

如果您使用MacPorts:

If you use MacPorts:

sudo port install bison

如果您使用Fink，它们就像Apple一样仍在2.3上，因此您必须自己编辑该软件包.

If you use Fink, they're still on 2.3, just like Apple, so you'll have to edit the package yourself.

如果您知道如何安装Unix软件，请下载该软件，解压缩，然后照常进行配置/制作/安装.

If you know how to install Unix software, download it, untar, then configure/make/install as usual.

如果以上所有内容都是希腊文，请查看 http://mxcl.github.com/homebrew/和 http://macports.org 并确定哪个对您更友好.

If all of the above are Greek to you, look at http://mxcl.github.com/homebrew/ and http://macports.org and decide which one looks friendlier to you.
