[英]No matching function for call to 'std::list<int, std::allocator<int> >::sort(<unresolved overloaded function type>)'
[英]no matching function for call to ‘bind(<unresolved overloaded function type>, const std::_Placeholder<1>&, int*)
#include <functional>
template <typename T>
void TemplateFunc(const int value, T* addr) {
}
void Register(std::function<void(const int)>&& callback) {
callback(2);
}
int main() {
int int_value;
Register(std::bind(&TemplateFunc, std::placeholders::_1, &int_value));
}
我不明白为什么?
详细日志:
test.cpp: In function ‘int main()’:
test.cpp:13:70: error: no matching function for call to ‘bind(<unresolved overloaded function type>, const std::_Placeholder<1>&, int*)’
Register(std::bind(&TemplateFunc, std::placeholders::_1, &int_value));

TemplateFunc
不是您需要提供template参数的函数名称:
Register(std::bind(&TemplateFunc<int>, std::placeholders::_1, &int_value));
