我有以下代码：

#include <iostream>
#define BOOST_TEST_MODULE my test
#include <boost/test/unit_test.hpp>

BOOST_AUTO_TEST_CASE( tmp_test )
{
    std::string str("");
    std::cout << "This is a simple test!" << std::endl;
}

//EOF

它编译和链接没有错误。

但是如果我尝试使用以下代码

#include <iostream>
#define BOOST_TEST_MODULE my test
#include <boost/test/unit_test.hpp>

BOOST_AUTO_TEST_CASE( tmp_test )
{
    std::string str("");
    BOOST_CHECK_EQUAL(str.length(), (size_t)0);
    std::cout << "This is a simple test!" << std::endl;
}

//EOF

我得到错误：

这里有什么问题？

显然，Ubuntu 11.04 附带的 gcc 中的参数顺序发生了变化。更多信息：Ubuntu 11.10 中的链接器问题

试试这个：

sudo apt install g++ cmake make libboost-dev
