C++ DirectX 9 未解析的外部符号

Question

是的，我包含了所有的库，但每次我运行我的 x64 程序都会给我一个未解析的符号，但在 x32 中完美运行？？

同样，很可能不使用包含，因为它像 x32 中的时钟一样工作。

Answer 1

x32 和 x64 具有不同的项目配置，因为您可能需要将它们指向每个体系结构的不同库位置。仔细检查以确保当您 select x64 时，库和包含目录仍然指向您的 DirectX 包含和 libs 文件夹。

您还需要确保在您的 includes 下

#include <d3d9.h>
#include <d3dx9.h>

你有

#pragma comment(lib, "d3d9.lib")
#pragma comment(lib, "d3dx9.lib")

Answer 2

使用旧版 DirectX SDK，您必须设置不同的 x86 与 x64 库包含路径：

在 VC++ 32 位配置的目录中：

$(IncludePath);$(DXSDK_DIR)Include
$(LibraryPath);$(DXSDK_DIR)Lib\x86

在 VC++ 64 位配置的目录中：

$(IncludePath);$(DXSDK_DIR)Include
$(LibraryPath);$(DXSDK_DIR)Lib\x64

见Microsoft Docs

For new projects you should be using Direct3D 11, and you do not need to use the legacy DirectX SDK at all.
