如题：配置编译参数通过，在进行 make 的时候报如下错误：

  1. In file included from progname.c:26:0:
  2. ./stdio.h:1010:1: error: ‘gets’ undeclared here (not in a function)
  3. _GL_WARN_ON_USE (gets, “gets is a security hole – use fgets instead”);
  4. ^
  5. make[2]: *** [progname.o] Error 1
  6. make[2]: Leaving directory `/usr/local/src/zabbix-2.4.7/libiconv-1.14/srclib’
  7. make[1]: *** [all] Error 2
  8. make[1]: Leaving directory `/usr/local/src/zabbix-2.4.7/libiconv-1.14/srclib’
  9. make: *** [all] Error 2

复制代码


解决方法：

使用 find 查找 stion.in.h 文件：

  1. [root@ip-172-31-29-70 libiconv-1.14]# find / -name ‘stdio.in.h’

复制代码


编辑该文件

  1. [root@ip-172-31-29-70 libiconv-1.14]# vim /usr/local/src/zabbix-2.4.7/libiconv-1.14/srclib/stdio.in.h

复制代码

通过关键字 gets 找到698 行，将其和695行一同注释：

  1. 695 /* It is very rare that the developer ever has full control of stdin,
  2. 696    so any use of gets warrants an unconditional warning.  Assume it is
  3. 697    always declared, since it is required by C89.
  4. 698 _GL_WARN_ON_USE (gets, “gets is a security hole – use fgets instead”);*/

复制代码

然后再注释的行下面添加以下三行：

  1. #if defined(__GLIBC__) && !defined(__UCLIBC__) && !__GLIBC_PREREQ(2, 16)
  2. _GL_WARN_ON_USE (gets, “gets is a security hole – use fgets instead”);
  3. #endif

复制代码

保存退出！（注意#endif 下面还有一个 #endif）：

重新编译即可！
