编译 libiconv-1.14 的时候出现 ./stdio.h:1010:1: error: 'gets' undeclared here (not in a function)

编译 libiconv-1.14 的时候提示函数未定义：

./stdio.h:1010:1: error: 'gets' undeclared here (not in a function)

cd 到 libiconv-1.14/srclib/stdio.h，打开

sudo gedit stdio.h

定位到 1010 行，发现是一个函数指针参数的宏函数：

_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");

文 http://blog.csdn.net/ownfire/article/details/47276219 给出了一种解决方法。还有一种更简单的解决方法就是注释：

---1010: _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
+++1010: //_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
