安装protoc
wget https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz
（此处下载https://code.google.com/p/protobuf/downloads/list）
解压， 进入根目录执行 sudo ./configure --prefix=/usr
若安装报错：
cpp: error trying to exec 'cc1plus': execvp: No such file or directory
则安装g++
sudo apt-get install g++
sudo make
sudo make check
sudo make install
protoc --version
遇到protoc: error while loading shared libraries: libprotoc.so.8: cannot open shared object file: No such file or directory时，如ubuntu系统，默认安装在/usr/local/lib下，需要指定/usr。sudo ./configure --prefix=/usr 必须加上--proix参数，重新编译和安装。

安装ant
1.首先下载ant
百度网盘： apache-ant-1.9.4-bin.tar.gz
http://pan.baidu.com/s/1c0vjhBy
或则下面链接：
2.解压
tar zxvf apache-ant-1.9.4-bin.tar.gz
3.配置环境变量
vim ~/.bashrc
export ANT_HOME=/home/xxl/apache-ant-1.9.4
export PATH=$ANT_HOME:$PATH
source ~/.bashrc

protobuf版本过低
安装2.5版本的即可
错误5：
- [ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.6:run (compile) on project hadoop-snappy: An Ant BuildException has occured: The following error occurred while executing this line:
- [ERROR] /home/ngc/Char/snap/hadoop-snappy/hadoop-snappy-read-only/maven/build-compilenative.xml:75: exec returned: 2
这个原因比较恶心，是因为Hadoop snappy对gcc版本还有要求，因为我是2012年12月份的ubuntu12.04，所以gcc已经是4.6了，但是在google code那看到有人说他从gcc4.6回退成gcc4.4就ok了，我也是了一下，果然这个错误没有了。
gcc --version #查看gcc版本
gcc (Ubuntu/Linaro 4.4.7-1ubuntu2) 4.6.3
Copyright © 2010 Free Software Foundation, Inc.

如何回退呢？
1. apt-get install gcc-4.4
2. rm /usr/bin/gcc
3. ln -s /usr/bin/gcc-4.4 /usr/bin/gcc
之后，再gcc --version，你就会发现，gcc已经变成4.4.7了。

网上有很多 解决/usr/bin/ld: cannot find -lxxx 这样的博客，但是这里，我告诉你，他们的都不适用。因为这儿既不是缺什么，也不是版本不对，是因为没有把安装jvm的libjvm.so symbolic link到usr/local/lib。如果你的系统时amd64，可到/root/bin/jdk1.6.0_37/jre/lib/amd64/server/察看libjvm.so link到的地方，这里修改如下：
ln -s /root/bin/jdk1.6.0_37/jre/lib/amd64/server/libjvm.so /usr/local/lib/
问题即可解决。
