centos7编译libiconv报错:./stdio.h:1010:1: error: 'gets' undeclared here (not in a function)
如题:配置编译参数通过,在进行 make 的时候报如下错误:
- 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
解决方法:
使用 find 查找 stion.in.h 文件:
find / -name 'stdio.in.h'
编辑该文件
vim /usr/local/src/zabbix-2.4.7/libiconv-1.14/srclib/stdio.in.h
通过关键字 gets 找到698 行,将其和695行一同注释:
- 695 /* It is very rare that the developer ever has full control of stdin,
- 696 so any use of gets warrants an unconditional warning. Assume it is
- 697 always declared, since it is required by C89.
- 698 _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");*/
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
保存退出!(注意#endif 下面还有一个 #endif):
#配置文件内容(如下)
#endif
#if defined(__GLIBC__) && !defined(__UCLIBC__) && !__GLIBC_PREREQ(2, 16)
_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
#endif
重新编译即可!
