Boost binding a function taking a reference
- by Jamie Cook
Hi all,
I am having problems compiling the following snippet
int temp;
vector<int> origins;
vector<string> originTokens = OTUtils::tokenize(buffer, ","); // buffer is a char[] array
// original loop
BOOST_FOREACH(string s, originTokens)
{
from_string(temp, s);
origins.push_back(temp);
}
// I'd like to use this to replace the above loop
std::transform(originTokens.begin(), originTokens.end(), origins.begin(), boost::bind<int>(&FromString<int>, boost::ref(temp), _1));
where the function in question is
// the third parameter should be one of std::hex, std::dec or std::oct
template <class T>
bool FromString(T& t, const std::string& s, std::ios_base& (*f)(std::ios_base&) = std::dec)
{
std::istringstream iss(s);
return !(iss >> f >> t).fail();
}
the error I get is
1>Compiling with Intel(R) C++ 11.0.074 [IA-32]... (Intel C++ Environment)

Google is being unusually unhelpful so I hope that some one here can provide some insights.
