A program in the company, there is a compiler Error C2872 error, how to debug can't. I have found some information from the Internet.
First look at MSDN explanation:
'Symbol': Ambiguous Symbol
The Compiler Could Not Determine Which Symbol You Are Referring To.
The Following Code Shows An Example of this Error.
Namespace a {
INT I;
}
USING NAMESPACE A;
INT I;
Void z () {
:: i ; // ok
A :: i ; // ok
i ; // error C2872, :: i or a :: i?
}
Means is a problem with namespace. There is an example on the Internet:
Example 2: The Following Sample Causes Compiler Error C2872 'Symbol': Ambiguous Symbol // Compile Options: / GX
#pragma Warning (Disable: 4786)
#include & ltioostream.h>
#include & ltioostream>
Using namespace std;
int main ()
{
Cout << "Hello World" << Endl; // C2872 Here
Return 0;
}
To workaround this problem, remove the using namespace directive. If you remove the using directive the cout from the old iostream is used. To use cout from the Standard C Library use fully qualified names for example, std :: cout.
