Compiler error when using TouchGFX code

[AWack]

I´ve created a project with TouchGFX, which works fine.

When I try to compile the project in CubeIDE I get the error ModelListener.hpp:9: undefined reference to `vtable for ModelListener

What could be the reason?

Best regards,

Hi,

I´ve nothing changed in the lines where the error occurs (contructor / destructor). And compiling with TouchGFX is sucessful! Only compiling with STM32CubeIDE fails!

I´ve the same code in an older project and it was possible to compile.

Best regards,

Achim
