Re: [Boost-users] [regex] invalid syntax for non-gready repeats

this inocent code throws an exception:

static const regex rpath( "Return-Path:(.*?)Received: ",

regex_constants::icase );

according to http://www.boost.org/libs/regex/doc/syntax.html this is how

non-gready repeats are specified.

Can anybody figure out what is wrong?

Yes, you need to tell the lib that it's a perl expression: static const regex rpath( "Return-Path:(.*?)Received: ", regex_constants::perl|regex_constants::icase ); John.
