Recompile all files, i.e. your app as well as the library. This is due to changes in header files which are not refelcted in all object files.

Maybe you use two different include directories.

This happens when you call a pure virtual method from a base class destructor/constructor. Check your code.
Example:
Code: Select all
class MyBaseClass {
public:
// Constructor calling virtual pure method
MyBaseClass() {
Init();
}
// Destructor calling virtual pure method
virtual ~MyBaseClass() {
Release();
}
// The pure virtual method
virtual void Init() = 0;
// The pure virtual method
virtual void Release() = 0;
}
class SomeClass : public MyBaseClass {
void Init() {
// Some code
}
void Release() {
// Some code
}
}
<edit> Btw some solutions:
- Do not call the method from constructor/destructor
- Give an empty code to the virtual pure method on the base class
</edit>

This has happened to me when I recompiled Irrlicht but forget to copy the new dll to where I need it (my demos are all self-contained).

Think the error you guys talk about is the one that reads:
Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.

By the way i modified the code example because it may happen within the constructor as well as within the destructor.
