Question

Building simple code (example is below) returns error on eclipse, while g++ from commandline doesn’t. Both eclipse and g++ output executable that act the same (and the result meets my expectation). This is painful when the code isn’t simple like the example I’m showing. Any idea is appreciated.

Env: Eclipse Indigo CDT, Ubuntu 10.10

Sample code:

//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();
}

Result of running the exec :

Build result in the ‘Problem’ tab on Eclipse:

I haven’t solved this issue (happens a lot particularly when I use boost it seems), but the root cause may lie in Eclipse’ CDT plug-in according to this thread. Brutal workaround is, as discussed in the page, to turn off code analysis feature.
