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.

I try but It does not work it sill appear

Maybe you use two different include directories.

[neppyweb]

so I should combine the libraries?

Huh?

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

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.
