Which branch / tag are you trying to build?

I also have the same issue. Trying to compile the linux-msft-wsl-5.10.y branch. Changed in .config file CONFIG_SOUND=y to enable ALSA dummy module compilation with the kernel. Compiling in Ubuntu 18.04 on WSL2.

I fixed this by changing the constants to enums in the driver dxgmodule.c file. Apparently, C does not regard const-qualified objects as constants, and as such, they cannot be used to initialize objects with static storage.

enum { DXGK_VMBUS_CHANNEL_ID_OFFSET = 192 };
enum { DXGK_VMBUS_VERSION_OFFSET = DXGK_VMBUS_CHANNEL_ID_OFFSET + sizeof(guid_t) };
enum { DXGK_VMBUS_VGPU_LUID_OFFSET = DXGK_VMBUS_VERSION_OFFSET + sizeof(u32) };
enum { DXGK_VMBUS_GUESTCAPS_OFFSET = DXGK_VMBUS_VERSION_OFFSET + sizeof(u32) };
