安装方法如下：
cd /usr/local/src wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz tar -zxvf libiconv-1.14.tar.gz cd libiconv-1.14 配置 ./configure --prefix=/usr/local/libiconv 编译 make 安装 make install 建立软连接 ln -s /usr/local/lib/libiconv.so /usr/lib ln -s /usr/local/lib/libiconv.so.2 /usr/lib
本人使用的是Cenos 7.0系统，因PHP需要 在编译安装libiconv-1.14时遇到如下问题：
故障1、 未安装GCC
cd libiconv-1.14 ./configure --prefix=/usr/local/libiconv configure: error: in `/home/gitlab/tools/libiconv-1.14': configure: error: no acceptable C compiler found in $PATH See `config.log' for more details
这个问题是因为没有安装GCC程序
解决办法：
yum install gcc -y
故障2、在make时报如下错误
In file included from progname.c:26:0: ./stdio.h:1010:1: error: ‘gets’ undeclared here (not in a function) _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead"); ^ make[2]: *** [progname.o] Error 1 make[2]: Leaving directory `/usr/local/src/zabbix-2.4.7/libiconv-1.14/srclib' make[1]: *** [all] Error 2 make[1]: Leaving directory `/usr/local/src/zabbix-2.4.7/libiconv-1.14/srclib' make: *** [all] Error 2
解决办法：
cd srclib/ #进入libiconv目录下的srclib sed -i -e '/gets is a security/d' ./stdio.in.h
