I was running Horde3D and tried to run it with the latest glfw(3.0), and only include the dlls. And I got everything working except the KeyEvent where I got a link error.
Error 1 error LNK2019: unresolved external symbol “bool __cdecl setupWindow(int,int,bool)” (?setupWindow@@YA_NHH_N@Z) referenced in function “void __cdecl keyPressListener(struct GLFWwindow *,int,int,int,int)” (?keyPressListener@@YAXPAUGLFWwindow@@HHHH@Z) F:\utveckling\gameLabb\ChicagoStandalone - Copy\main.obj ChicagoStandalone
The Horde3D example im running is Chicago. And if I remove the KeyEvent everything else works with mouse input and rendering. Any idea what might would be wrong?
I also tried to compile glfw to dlls but I cant figured it out, so I downloaded the glfw-3.0.bin.WIN32 and used the dlls and lib from that package. I also tried other version of the glfw.win32 packages but then a got alot more link errors.
Sorry I should have provided more info. But it is from glfw I encounter the problem.
This is what i set up, and it is from the glfw3.h:
/*! @brief The function signature for keyboard key callbacks.
*
* This is the function signature for keyboard key callback functions.
*
* @param[in] window The window that received the event.
* @param[in] key The [keyboard key](@ref keys) that was pressed or released.
* @param[in] scancode The system-specific scancode of the key.
* @param[in] action @ref GLFW_PRESS, @ref GLFW_RELEASE or @ref GLFW_REPEAT.
* @param[in] mods Bit field describing which [modifier keys](@ref mods) were
* held down.
*
* @sa glfwSetKeyCallback
*
* @ingroup input
*/
typedef void (* GLFWkeyfun)(GLFWwindow*,int,int,int,int);
and this is how i set it up:
glfwSetKeyCallback( window, keyPressListener );
static void keyPressListener(GLFWwindow* window, int key, int scancode, int action, int mods )
I got glfwSetCursorPosCallback( window, mouseMoveListener ); and glfwSetWindowCloseCallback( window, windowCloseListener ); to work with the same approach but not for glfwSetKeyCallback
Thanks you very much It was my own method that was wrong. So now I got it running. Im quite new to C++ so I don’t understand the link errors so well.
By the way do you know if there is a guide how to build dynamic libraries from C in visual studio? I searched but didn’t find any good straight on guide for a newbie as my self.
