Re: initializing public static const std::string member

Code compiles, but the string evaluates to NULL in debugger. Using gcc
3.1.1.
Did I not initialize the string properly or is this a compiler bug?
What does it mean "the string evaluates to NULL in debugger"?
If you don't know whether the string has been initialised or not,
put the breakpoint in every std::string constructor so that you
know when one is actually constructed.
// some.h
#include <string>
namespace ns
{
class SomeClass
{
public:
SomeClass() {}
~SomeClass() {}
static const std::string mystring;
void Test();
};
} // namespace
// some.cpp
#include "some.h"
namespace ns
{
const std::string SomeClass::mystring = "Somestring";
void SomeClass::Test()
{
// somestring evaluates to NULL and seg faults here!!!
I am not sure I understand that comment.
cout << mystring + mystring;
Not sure 'cout' is defined here. Did you include <iostream>?
}
}
// main.cpp
#include "some.h"
int main()
{
ns::SomeClass tester;
ns::SomeClass.Test();
'Test' is non-static member. You cannot call it without
an instance. Did you mean
tester.Test();
?
return 0;
}
Please post the _actual_ code that exhibits the error you are
trying to correct.
While it is possible that it's a bug in the compiler, there is
no way to conclude that if the code you post doesn't even compile.
For the testing purposes (when you're trying to figure out if it
is or isn't a compiler bug), you need to try different things,
like putting everything in the same translation unit.
