二、解决方法
编辑/home/chen/tools/libiconv-1.14/srclib下的stdio.in.h，找到如下代码：
_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
改为如下代码：
#if defined(__GLIBC__) && !defined(__UCLIBC__) && !__GLIBC_PREREQ(2, 16) _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
#endif
#endif
注意：上面为两个#endif保存退出，重新编译。
make && make install
