如何卸载protobuf

Question

我在osx上安装Hadoop，由于Hadoop没有64位mac本地库，需要编译Hadoop。通过git clone 安装的probuf3.0版本，结果编译的时候提示必须使用2.5版本。请问如何卸载3.0版本。
我删除了目录下protobuf文件夹，但是在terminal输入命令
protoc --version
依然显示libprotoc 3.0.0
到底应该如何卸载

Answer 1

简单粗暴的办法：

1. which protoc找到文件位置，比如我的mac上是/usr/local/bin/protoc。

2. 执行sudo rm /usr/local/bin/protoc就可以了。

Answer 2

使用make uninstall
To remove all libraries built with make, go to the folder where the protoc files were downloaded and run make uninstall. That worked. However, when I checked again with protoc --version, I still got libprotoc 3.0.0. I think the reason is because I followed one of he instructions to change the path of the installation (./configure --prefix=/usr) and therefore I needed to use rm which protoc to manually delete the leftovers from protoc 3, because the make unistall was not pointing to it. After that, protoc was completely gone.
