make[1]: *** [install-pear-installer] Error 127
在安装php过程中make install时候的报错：
Installing PEAR environment: /usr/local/php/lib/php/
/home/sysadmin/zhaoyj/software/php-5.2.17/sapi/cli/php: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory
make[1]: *** [install-pear-installer] Error 127
make: *** [install-pear] Error 2
但是在/usr/local/lib下却能找到libiconv.so.2
[root@XKWB5510 php-5.2.17]# find / -name libiconv.so.2
/usr/local/lib/libiconv.so.2
/home/sysadmin/zhaoyj/software/libiconv-1.13.1/lib/.libs/libiconv.so.2
先尝试着创建一下软连接
ln -s /usr/local/lib/libiconv.so.2 /usr/lib/libiconv.so.2
使用此方法的时候需要考虑到在configure时的支持选项--with-iconv-dir=/usr/local，所以创建连接这方式可能是无效的
解决方法是将/usr/local/lib路径添加到/etc/ld.so.conf文件中，
然后用ldconfig命令加载，再重新输入make install命令就可以了
[root@XKWB5510 php-5.2.17]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/lib
php编译成功了
[root@XKWB5510 php-5.2.17]# make install
