In general if your program binary is directly linked to the API library (stub) (in contrast to using a loader that loads the API library (stub) at runtime, dynamically), it's quity silly to retrieve functions being part of the OS's OpenGL ABI contract with *gl*GetProcAddress as these function are available through the regular API library anyway. It is not required that it returns addresses for functions found in the operating systems OpenGL ABI requirements (OpenGL-1.1 for Windows, OpenGL-1.2 for Linux Softare Base (LSB) 4, OpenGL-2.1 for LSB-5).

*gl*GetProcAddres is specified only for returning entry point addresses for extended functionality. No more void * (except for the return value of wglGetProcAddress, which is casted). Since the type is now FnPtr*, whatever you pass in will automatically have FnPtr be of that type. *_pFunc = reinterpret_cast(wglGetProcAddress( _cName )) _pFunc = (void *)wglGetProcAddress( _cName ) // īool CGLManager::GetAnyGLFuncAddress( const char *_cName, FnPtr* _pFunc )

Let's cut out all of the code that is irrelevant and focus on this: bool CGLManager::GetAnyGLFuncAddress( const char *_cName, void *_pFunc ) However, due to the nature of the environment I'm working on, I can't use those kind of libraries and neither I can't use OpenGL functions directly, I know I'm going through the painful way by doing everything manually but I have no other choice.įorgetting about what your ultimate goal is, I see basic C++ mistakes. In many websites and answers I've found on StackOverflow, a lot of people suggested to use an OpenGL loading library like GLEW and even the OpenGL wiki recommend it. I have been trying for hours to find out a solution by searching on Internet and on StackOverflow but I haven't found any answer that can give me the solution to the problem. Now the problem : the GetAnyGLFuncAddress method retrieve successfully OpenGL functions (in other words, glBegin will return true, glARandomMethodThatDontExist will return false) but for some reason, gGL.glBegin (and it's 'friends') in LoadFunctions doesn't get updated and it will be always NULL causing a crash. Otherwise, we load the library ( opengl32.dll or libGL.so) and we check if it's good or not (again, if failed, we stop), we retrieve and store the pointers to OpenGL's functions ( glBegin, glEnd, glVertex3f) with the LoadFunctions method and we return if everything's fine or something wrong happened. Here's how my manager work in general : it first check which renderer the game's engine uses (Software, OpenGL or Direct3D), if it's not OpenGL, then we stop getting any further. If ( !(GetAnyGLFuncAddress( 'glVertex3f', &gGL.glVertex3f )) ) If ( !(GetAnyGLFuncAddress( 'glEnd', &gGL.glEnd )) )

If ( !(GetAnyGLFuncAddress( 'glBegin', &gGL.glBegin )) ) LoadFunctions - Attempt to retrieve all used OpenGL functions, returns true if all of them were retrieved or false if there is a single failure _pFunc = (void *)glXGetProcAddress( _cName ) _pFunc = (void *)glXGetProcAddressARB( _cName )

I changed the version of Qt to 5.12.4, when I try to run the project in Windows 10 I have a crash with this Errors (No problem in Windows 7 with the Qt 5.12.4)Ĭritical: Failed to load libGLESv2d (Les ressources mémoire disponibles sont insuffisantes pour traiter cette commande.) I need your help please, I have a 3D project that works perfectly with Qt 5.9 in two platforms windows 10 and 7.
