Eclipse为g ++没有的代码返回错误

Question

构建简单代码(例如下面的代码)会在eclipse上返回错误,而来自命令行的g ++则不会.eclipse和g ++输出可执行文件的行为相同(结果符合我的期望).当代码不像我正在展示的例子那样简单时,这很痛苦.任何想法都表示赞赏.

环境:Eclipse Indigo CDT,Ubuntu 10.10

示例代码:

//For test_boostStr()
#include <boost/algorithm/string.hpp>
#include <vector>
#include <iostream>

//For test_boost_foreach()
#include <boost/algorithm/string/trim.hpp>
#include <boost/foreach.hpp>

void test_boostStr() {
    std::vector<std::string> strs;
    boost::split(strs, "string to split", boost::is_any_of("\t "));
    std::cout << strs.size() << std::endl;
    //  std::cout << strs.at(1) << std::endl;
}

void test_boost_foreach() {
    //std::vector<std::string> namespaces_;
    std::string namespaces_  = " tele op eration. ";
    std::cout << "managing namespaces: ";
    std::string out;
    std::string s;
    BOOST_FOREACH(s, namespaces_)
    {
        boost::trim(s);
        out += s + " ";
    }
    std::cout << out.substr(0, out.size() - 1) << std::endl;
}

int main(void) {
    test_boost_foreach();
}

运行exec的结果:

在Eclipse的"问题"选项卡中构建结果:

我还没有解决这个问题（似乎经常发生，特别是当我使用 boost 时），但根据这个线程，根本原因可能在于 Eclipse 的 CDT 插件。正如页面中所讨论的，残酷的解决方法是关闭代码分析功能。
