How to use Regex with GCC 4.8.2

How to use Regex with GCC 4.8.2

My setup:

Operation system: Ubuntu 14.04
Compiler: GCC 4.8.2
IDE: Eclipse 3.8.1

Problem:

I've included regex (#include <regex>) to my header file but my IDE keeps complaining that type of 'something' could not be resolved. I've tried using namespaces such as std:: and std::tr1, like people from google has adviced, with no success.

Solution:

Solution is as simple as the problem itself. If you take a look at usr/include/c++/4.8 you'll notice the regex file in root folder is kind of a stub. However there's another regex file in /tr1 folder.

The trick is, that instead of writing #include <regex>, you should write #include <tr1/regex>

After that you're able to use regex through std::tr1:: namespace.

For exmaple like this: std::tr1::smatch

Hope that helps!
