编译ant compile-native遇到的一些问题

环境：

Ubuntu Server12.04

Hadoop1.2.1

问题1：缺少autoreconf

解决方法：安装下就解决了

hadoop@grc:~/hadoop-1.2.1$ sudo apt-get install autoconf libtool

问题2：编译过程中卡在ivy-retrieve-common这段代码上很长时间

愿意是因为主要是这个target 依赖的jar比较多，且在第一次编译的时候都需要联网下载。
build.xml 代码块：

<target name="ivy-resolve-common" depends="ivy-init">    <ivy:resolve settingsRef="${ant.project.name}.ivy.settings" conf="common"  log="${loglevel}"/>  </target>

viy.xml 依赖列举部分代码块：

<!--Private configurations. -->    <conf name="common" visibility="private" extends="runtime,mandatory,httpclient,ftp,jetty"                      description="common artifacts"/> <conf name="mandatory" description="contains the critical  dependencies"      extends="commons-logging,log4j"/>    <!--Configuration: commons-logging -->    <!--it is essential that only the master JAR of commons logging    is pulled in, as its dependencies are usually a mess, including things    like out of date servlet APIs, bits of Avalon, etc.    -->    <dependency org="commons-logging"      name="commons-logging"      rev="${commons-logging.version}"      conf="commons-logging->master"/>

总共最终在~/.viy/cache 下 缓存了24M的文件。慢是正常的，不要出现连接超时就是不错的。

问题3：

[exec] configure: error: Zlib headers were not found... native-hadoop library needs zlib to build. Please install the requisite zlib development package.     [exec] checking zlib.h usability... no     [exec] checking zlib.h presence... no     [exec] checking for zlib.h... noBUILD FAILED/home/hadoop/hadoop-1.2.1/build.xml:627: The following error occurred while executing this line:/home/hadoop/hadoop-1.2.1/build.xml:694: exec returned: 1Total time: 20 minutes 23 seconds

解决方法：安装zlib
1、从官网下载zlib包。官方网站：http://www.zlib.net
2、解压 tar -zxvf zlib-1.2.8.tar.gz （目前最新的版本是1.2.8）
3、$cd zlib-1.2.8
4、$ ./configure 
5、$make
6、$sudo make install
安装完成
