Tomcat 安装APR的问题

APR、APR-util、APR-iconv安装都正常
apr安装命令：
./configure
make
make install

apr-util
./configure --with-apr=/usr/local/apr/bin/apr-1-config
make
make install

apr-iconv(可选)
./configure --with-apr=/usr/local/apr/bin/apr-1-config
make
make install

然后到$Tomcat_home/bin
解压tomcat-native.tar.gz
进入tomcat-native-1.1.x/jni/native/
执行命令
./configure --with-apr=/usr/local/apr/bin/apr-1-config
出错：
configure:error:can't locate a valid JDK location
但是我机器上有安装JDK并且配置了JAVA_HOME，网上搜资料后发现此程序只会到以下默认的目录寻找JDK：
02.configure: [/ usr/local/1.6.1]
03.configure: [/ usr/local/IBMJava2-1.6.0]
04.configure: [/ usr/local/java1.6.0]
05.configure: [/ usr/local/java-1.6.0]
06.configure: [/ usr/local/jdk1.6.0]
07.configure: [/ usr/local/jdk-1.6.0]
08.configure: [/ usr/local/1.6.0]
09.configure: [/ usr/local/IBMJava2-1.6]
10.configure: [/ usr/local/java1.6]
11.configure: [/ usr/local/java-1.6]
12.configure: [/ usr/local/jdk1.6]
13.configure: [/ usr/local/jdk-1.6]

于是乎，建个链接到我的jdk目录
ln -s /usr/java/jdk1.7.0_25  /usr/local/jdk-1.6

继续安装
./configure --with-apr=/usr/local/apr/bin/apr-1-config
make
make install

到此安装成功。

设置环境变量

set LD_LIBRARY_PATH=/usr/local/apr/lib
export LD_LIBRARY_PATH

最后将链接库加入JRE中
ln -s /usr/local/apr/lib/libtcnative-1.so /usr/java/jdk1.7.0_25/jre/lib/libtcnative-1.so

重启Tomcat后APR安装完成
