Building RenderSystem_Direct3D9 with Visual Studio 2015

[PBY]

As some have already seen, RenderSystem_Direct3D9 don't link when building with Visual Studio 2015:

Code: Select all

DxErr.lib(dxerra.obj) : error LNK2019: unresolved external symbol _vsnprintf referenced in function "long __cdecl StringVPrintfWorkerA(char *,unsigned __int64,unsigned __int64 *,char const *,char *)" (?StringVPrintfWorkerA@@YAJPEAD_KPEA_KPEBD0@Z)

Sure, DxErr.lib was build (DirectX SDK June 2010) with an older version of VS. But _vsnprintf is still there: https://msdn.microsoft.com/en-us/library/1kt27hek.aspx

And removing

Code: Select all

#include <DxErr.h>

in OgreD3D9Prerequisites.h don't help (it must be included by other DirectX headers).

Was anyone able to resolve this issue? Or are we stuck to use VS2013 forever (Microsoft only support DirectX 9 in WPF )

Hello,

I have exactly the same issue by using VS2015. Is there any workaround available?

Best regards,

Hi again,

I think I found a workaround. The issue is, that the DX9 SDK is compiled with a much older version of visual studio and static libraries are not fully compatible to each other. Unfortunately M$ does not support this old SDK for new compilers, so the only way is to recompile the dxerr library by yourself. Of course you cannot access the original code from M$, but there is a very interesting wrapper available, that make the original dxerr.h functions available by using inside the new FormatMessage function instead of vprintf.

This is the link to the blog and files: http://blogs.msdn.com/b/chuckw/archive/ ... r-lib.aspx
(you find the files as ZIP at the end of this blog entry, copy them to a folder named "src" and use cmake with the following cmake file to compile a dxerr.lib out of it)

cmake-file:

Code: Select all

# -*- cmake -*-
cmake_minimum_required(VERSION 3.3)
PROJECT(dxerr)

## section: include directory

#  includes

LIST(APPEND DXERR_SOURCE_FILES ${DXERR_HEADER_FILES})

	-D_LIB;-D_STLP_DEBUG;
	)

INSTALL(TARGETS dxerr

		RUNTIME DESTINATION  "bin" CONFIGURATIONS Debug Release MinSizeRel RelWithDebInfo
		)
INSTALL(FILES ${DXERR_HEADER_FILES} DESTINATION "includes")		

Unfortunately DXGetErrorDescription function prototype is different here and Ogre3D is using the non Unicode-Function, that is not supported by this dxerr-wrapper.
However I was able to adapt the wrapper code in a way that it fits to the original prototype and I also added a non Unicode version.
Due to license reasons I cannot offer the full code to you, but as a fast solution you can simply use a static WCHAR[32000] array inside the function and return the pointer to that array. This is not a nice approach but the easiest one.
For adapting to non-Unicode, you can use this code (is also using a static array):

Code: Select all

const char*  WINAPI DXGetErrorDescriptionA(__in HRESULT hr)
{
	WCHAR const * pUnicodeStr = DXGetErrorDescriptionW(hr);
	static char ASCIIStr[32000];
	wcstombs(ASCIIStr, pUnicodeStr, 31999);
	return ASCIIStr;
}

I think for a first approach this is ok. Later I should have another look here to implement it in a more clean way.

BTW: Remember to add the ifdef/else/endif for the #define DXGetErrorDescription to the wrapper header like it was in the original DX9 dxerr.h

It sound quite good, I will try it when I have some time (we are now releasing a new version of our software, and we will make the complete switch to VS2015 after that, if Ogre compiles).

As FormatMessage seems to be the official Microsoft solution when DXErr disappears from Directx in Windows 8, this wrapper should be the best way to still use DirectX9.

Thanks a lot.

You just linked the thread your own post is in. I'm sure that doesn't help.
