Hi,<br>I have been using the regular expressions with the older version of boost::regex, But with the latest version I&#39;m getting the below error.<br>I understand reg_expression is deprecated and need to use basic_regex. But even with that, its the same error.<br>

<br>Any ideas on this, would be more useful.<br><br>typedef boost::reg_expression&lt;char, boost::c_regex_traits&lt;char&gt;, ntl::list_alloc&lt;char&gt; &gt; Exp_type;<br><br>../../../include/expr/ExprEngine.h:38: error: wrong number of template arguments (3, should be 2)<br>

../../../include/boost/regex/v4/basic_regex.hpp:597: error: provided for &#39;template&lt;class charT, class traits&gt; class boost::reg_expression&#39;<br><br>Thanks<br>rsennat<br>
