The following code builds without warnings on g++ -std=c++0x but CDT says "symbol bar could not be resolved." Bug?

#include <iostream>
using namespace std;

void f(int i) {
	cout << "foo" << i << endl;
}

template<typename... T>
struct Foo
{
	template<void(*fp)(T...)>
	static void bar(T... t) { fp(t...); }
};

int main()
{
	Foo<int>::bar<f>(3);
        return 0;
}

Sorry, that doesn't help.

Changing Open Project Properties->C/C++ Build ->Settings->Tool Settings->GCC C++ Compiler->Miscellaneous->Other Flags to -std=c++0x doesn't affect anything.

I couldn't find a "compiler invocation arguments" field in "Project Properties->C/C++ Build ->discovery Options"

Any ideas?

Thanks,

Mike

When I go to Project Properties->C/C++ General_>Preprocessor Include Path, Macros, etc., I don't see any place to add compiler options like "-std=c++0x" What am I missing?

Thanks,

Mike

Thanks, Klaus, that was useful and made some of my C++0x scanning work better, but it still doesn't solve the original problem I first posted on. Does that code display without an error marker in CDT for anyone?
