CentOS7 编译安装libiconv报错：./stdio.h:1010:1: error: 'gets' undeclared here (not in a function)

1. libiconv编译时遇到以下报错

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

2. 解决问题

2.1 使用 find 查找并编辑 stion.in.h文件

[root@Tubao libiconv]# find / -name 'stdio.in.h'
/server/tools/libiconv-1.14/srclib/stdio.in.h

2.2 通过关键字 gets 找到698 行，将其和695行一同注释

2.3 然后再注释的行下面添加以下三行

#if defined(__GLIBC__) && !defined(__UCLIBC__) && !__GLIBC_PREREQ(2, 16)
_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
#endif

2.4 整体效果图，从695到702行
