【问题描述】：

我正在尝试在 MIPS 平台上交叉编译 Zeromq 库。 2.2、3.2.4、4.0.4都试过了，都没有通过配置检查

设置了环境变量CC、CPP、CXX、LD、AR、RANLIB。然后我运行 ./configure --host=mips

Linux 内核：2.6.31
gcc 版本：4.3.3

【解决方案1】：

首先，如果出现错误，请禁用 epoll

功能未实现 (epoll.cpp:41)

中止

配置前

导出 CXXFLAGS=-DZMQ_FORCE_POLL

开始交叉编译

使用

./configure --host=mips-linux

输入make时可能会出错

通过在 array.hpp 中添加一些行来修复它

#ifdef index
#undef index
#endif

#ifndef __ZMQ_ARRAY_INCLUDED__
#define __ZMQ_ARRAY_INCLUDED__

#include <vector>
#include <algorithm>

namespace zmq 
{
