Re: [Boost-users] boost::reg_expression and basic_regex

I have been using the regular expressions with the older version of boost::regex, But with the latest version I'm getting the below error. I understand reg_expression is deprecated and need to use basic_regex. But even with that, its the same error.

Any ideas on this, would be more useful.

typedef boost::reg_expression Exp_type;

../../../include/expr/ExprEngine.h:38: error: wrong number of template arguments (3, should be 2) ../../../include/boost/regex/v4/basic_regex.hpp:597: error: provided for 'template class boost::reg_expression'

Looks like the final Allocator template parameter got dropped about 7 years ago from reg_expression... and no one noticed! Remove the Allocator parameter and everything should be OK (this is documented for basic_regex BTW: http://www.boost.org/doc/libs/1_43_0/libs/regex/doc/html/boost_regex/ref/bas...). HTH, John.
