I've still not managed to get any headway on getting this to compile. Here's
my code:
If(this->mod->getConfigEntry("Feature") != NULL) {
sword::ConfigEntMap::iterator begin;
sword::ConfigEntMap::iterator end;
begin = this->mod->getConfig().lower_bound("Feature");
end = this->mod->getConfig().upper_bound("Feature");
while(begin != end) {
featureSet += "Feature: ";
featureSet += begin->second;
featureSet += "\n";
++begin;
}
}
Where featureSet is a std::string.
And this is the output of the compiler.
