I'm trying to build an old application using a Windows XP Professional SP3 virtual machine. I set the environment with mingw and all is ok except for this error during building process:

error: 'struct _DDSURFACEDESC2' has no member named 'DUMMYUNIONNAMEN'

Seems that the ddraw.h header coming from mingw has a different structure. I tried to remove the DUMMYUNIONNAMEN from the source code like this:

// desc is passed as argument, initialized elsewhere
// desc type --> LPDDSURFACEDESC2
int depth = desc->DUMMYUNIONNAMEN(4).ddpfPixelFormat.DUMMYUNIONNAMEN(1).dwRGBBitCount;

that I replaced with this:

int depth = desc->ddpfPixelFormat.dwRGBBitCount;

In this way it builds but when I run the application I got sometimes an ACCESS VIOLATION error and sometimes (with different input file) no video (black window, only audio)

CodePudding user response：

Using ddraw.h from dx9sdk resolved the problem of DUMMYUNIONNAMEN. For the segmentation fault I opened another question
