<div>if the compiler options have side effects so I post my options as below:</div><div><br></div><div>/Od /D &quot;_MBCS&quot; /Gm /EHsc /RTC1 /MDd /Fo&quot;Debug\\&quot; /Fd&quot;Debug\vc90.pdb&quot; /W3 /nologo /c /ZI /TP /errorReport:prompt</div>
<div><br></div><div>Lastly, have you replaced std::string with const std::string? That will cause the &quot;find&quot; within &quot;find_first&quot; resoluted as the &quot;find&quot; in range/algorithm/find.hpp in my test environment.</div>

<div>The compiler will complain ambiguous call to overload function &quot;find&quot;. I found there&#39;s also a &quot;find&quot; in&nbsp;boost/range/algorithm.hpp. Even worse when I change the type of &quot;s&quot; to const std::string, the compiler will resolute &quot;find&quot; call as the one in boost/range/algorithm.hpp</div>




<div>and reports an error &quot;const_iterator is not a member of std::_String_const_iterator&quot;. Now I just indicated the &quot;find&quot; call in boost::find_first explicitly. Is there a better way to solve it?</div>

This code compiles cleanly for me. I noticed that you are talking about
&quot;find&quot; rather than &quot;find_first&quot; so I took the liberty of replacing the
&quot;find_first&quot; with &quot;find&quot;. This indeed produced a compiler error similar
to the one you describe. However boost::find(s, &quot;lo&quot;) does not match
the boost/algorithm/string.hpp version because the second parameter
should be a &quot;Finder object used for searching&quot;. Please see:<br><a href="http://www.boost.org/doc/libs/1_39_0/doc/html/string_algo/reference.html#header.boost.algorithm.string.find_hpp" target="_blank">http://www.boost.org/doc/libs/1_39_0/doc/html/string_algo/reference.html#header.boost.algorithm.string.find_hpp</a><br>

<br>It also does not match
the RangeEx version because &quot;find&quot; is used to find an element, as opposed
to a sub-sequence, from a range. Therefore I conclude that either, I have
guessed the code snippet that causes the problem inaccurately, or that
the code that produced the compiler error was simply incorrect.<br>
<br>
If I have guessed the code wrongly, would you please supply the exact
code that reproduces the problem. I suspect that find_first is exactly
the right solution. Please let me know either way.<br>&nbsp;
