Problems with Boost Regex in Eclipse CDT
I'm developing a small game using SDL and recently added a basic parser using boost regex to avoid hardcoding lots of statistical data... after I finally ironed out all the errors and none
of my code threw any errors CDT sudden spat out a pageful of errors involving the boost files themselves. I, or anyone I have talked to have been at a loss to describe what exactly is going
on never mind how to fix it...
The errors...

The code using regex (there are three functions like this... they are nearly identical except for some defaults and types)...
Code:
std::list<boost::shared_ptr<ProjectileType> > parseProjectiles(std::string file)
{
std::list<boost::shared_ptr<ProjectileType> > projyTypes;
std::map<std::string,std::string> tags;
std::ifstream input;
input.open(file.c_str(),std::ios::in);
std::string fileData((std::istreambuf_iterator<char>(input)), std::istreambuf_iterator<char>());
boost::regex bracketRule("\{(. | \n)*?}", boost::regex::icase);
boost::smatch bracketResults;
boost::regex tagRule(" *?(.*)? *?= *?(.*)? *?\n", boost::regex::icase);
boost::smatch tagResults;
std::string::const_iterator startB, endB, startT, endT;
startB = fileData.begin();
endB = fileData.end();
while (boost::regex_search(startB, endB, bracketResults, bracketRule))
{
tags["name"] = "loller";
tags["velocity"] = "500";
tags["areaofeffect"] = "0";
tags["damage"] = "1";
tags["graphic"] = "data/projectiles/bullet.png";
startT = bracketResults.str(1).begin();
endT = bracketResults.str(1).end();
while (boost::regex_search(startT, endT, tagResults, tagRule))
{
tags[tagResults[1]] = tagResults[2];
}
boost::shared_ptr<ProjectileType> newprojy(new ProjectileType(tags));
projyTypes.push_back(newprojy);
}
return projyTypes;
}
Sorry about the massive post width but I figured those errors should be formatted properly.
