The code is wrong because it pulls in two version of isspace
* one in <cctype> -- the traditional C function;
* another in <locale> -- the C++ only version that takes two
arguments: the locale and the character.
and then is trying to use the second version in place of the first.
Try to add
struct Isspace {
bool operator()(int c) const { return isspace(c); }
};
and try
find_if (d.begin(), d.end(), Isspace());
Also hae a look at:
