Question

In the following class:

class TestClass
{
public:
     int staic testMember;
};

int TestClass::testMember;

I’ve got the following compiler error:

error LNK2005: “public: static float TestClass::testMember” (?testMember@TestClass@@2MA) already defined in TestClass.obj

Note: I’ve tried to simulate the problem in a seperated application but everything worked well there.

I wonder where is the problem here?

Answer 1

Your definition:

int TestClass::testMember;

…is probably in the same H file as the declaration:

class TestClass
{
public:
     int staic testMember;
};

Move the definition to it’s own CPP file. You need to define it only once.
