xpressive enum clashing with glx

Reported by: benjamin.prestele@… Owned by: Eric Niebler
Milestone: To Be Determined Component: xpressive
Version: Boost 1.53.0 Severity: Problem
Keywords: Cc:

Description

On Ubuntu 12.04, some header included by GL/glx.h seems to define a macro 'None', which replaces the enum by the same name in boost/xpressive/match_results.hpp at line 122. Therefore the following simple testcase fails to compile:

#include <GL/glx.h>
#include "boost/xpressive/xpressive.hpp"

int main( int argc, char** argv )
{
  return 0;
}

Giving the following error with g++:

                 from ../workspace/Boost_1_53_0/boost/xpressive/detail/core/state.hpp:18,
