Mac安装Antlr生成C++代码

一、安装Antlr https://github.com/antlr/antlr4/blob/master/doc/getting-started.md

0. 安装 Java (version 1.7 or higher)
1. 下载Antlr

2. $ cd /usr/local/lib
   $ curl -O https://www.antlr.org/download/antlr-4.10.1-complete.jar
   

或者官网下载：https://www.antlr.org/download.html 并将其放在 /usr/local/lib目录

2. 添加 antlr-4.10.1-complete.jar 到CLASSPATH环境变量:

3. $ export CLASSPATH="$CLASSPATH:/usr/local/lib/antlr-4.10.1-complete.jar"
   

也可以将其放在.bash_profile 或启动脚本中

3. 为ANTLR Tool和TestRig创建别名

4. $ alias antlr4='java -Xmx500M -cp "/usr/local/lib/antlr-4.10.1-complete.jar:$CLASSPATH" org.antlr.v4.Tool'
   $ alias grun='java -Xmx500M -cp "/usr/local/lib/antlr-4.10.1-complete.jar:$CLASSPATH" org.antlr.v4.gui.TestRig'
   

二、安装C++运行时库 https://github.com/antlr/antlr4/tree/master/runtime/Cpp
