编译安装libiconv
cd /usr/local/src
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar xfz libiconv-1.14.tar.gz
cd libiconv-1.14
./configure --prefix=/usr/local/libiconv
make
make install
cd ..
make时遇到错误：

make[1]: 离开目录“/usr/local/src/libiconv-1.14/srclib”
make: *** [all] 错误 2
解决办法1：
编辑stdio.h文件，将 _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");字段部分内容改为如下：
- #if defined(__GLIBC__) && !defined(__UCLIBC__) && !__GLIBC_PREREQ(2, 16)
- _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
- #endif
- #endif
解决办法2：
cd srclib/
sed -ir -e ‘/gets is a security/d‘ ./stdio.in.h
cd ../
make
重新make即可！
