Linker error when using qMin(), qMax(), qBound()

[zavulon]

Trying to use static const members in functions qMin(), qMax(), qBound() gives a linker error:
undefined reference to `<the static constant>'.

Here is an example code:

class Test
{
public:
static const float KValue=3.0;
Test();
};
 
Test::Test()
{
// Can be any function, not only a constructor
float foo = 1.0;
foo = qMax( foo, KValue );
}
 
int main()
{
// somewhere in a program
Test obj;
}

class Test
{
public:
static const float KValue=3.0;
Test();
};

Test::Test()
{
// Can be any function, not only a constructor
float foo = 1.0;
foo = qMax( foo, KValue );
}

int main()
{
// somewhere in a program
Test obj;
}

On the other hand, when using usual local constants, qMax (and friends) works ok:

float foo = 1.0;
const float value = KValue; // Make a copy of the static constant
 
foo = qMax( foo, value );

float foo = 1.0;
const float value = KValue; // Make a copy of the static constant

foo = qMax( foo, value );

To copy to clipboard, switch view to plain text mode 

Please write, if someone knowswhy this happens or any good workarounds.
