Hi,<br><br>I&#39;ve a Dev-Cpp, mingw, Windows XP development environment.<br>I&#39;m trying to develop an application based on Regex but I&#39;m not able to run even the simple example from<br>&quot;Getting Started&quot; section of Boost documentation or the &quot;Credit Card Numbers&quot; example from Regex.<br>
<br>I&#39;ve built the library through different ways (trying just to build the regex library from John&#39;s homepage or<br>building the whole Boost library through bjam). The building process was always OK and I&#39;m pretty sure<br>
that I&#39;m correctly linking the files in Dev-Cpp (I also used the path described at <a href="http://wagjo.com/index.php?id=27">http://wagjo.com/index.php?id=27</a>).<br><br>However, I always get similar result: a lot of compiler messages saying that I have &quot;multiple definitions of something&quot;.<br>
<br>Does anyone in this list could help me?<br><br>Here is the compiler log from one of the many tentatives that I&#39;ve made (sorry about huge text):<br><br>Compiler: OpenCV+Regex<br>Building Makefile: &quot;C:\Documents and Settings\pdcosta\Desktop\Makefile.win&quot;<br>
