在python中使用cppyy时，指针变量raise错误为未知类型 所以我有这个，这里是C++中的，所以我安装了CPpyy，但是当我用Python中包含CPYY的头文件时，它会引起错误 // MysticLight_SDK.h : header file // #pragma once typedef int (*LPMLAPI_Initialize)(); typedef int (*LPMLAPI_GetDeviceInfo)(SAFEARRAY** pDevType, SAFEARRAY** pLedCount); typedef int (*LPMLAPI_GetDeviceName)(BSTR type, SAFEARRAY** pDevName); typedef int (*LPMLAPI_GetDeviceNameEx)(BSTR type, DWORD index, BSTR* pDevName); typedef int (*LPMLAPI_GetErrorMessage)(int ErrorCode, BSTR* pDesc); typedef int (*LPMLAPI_GetLedName)(BSTR type, SAFEARRAY** pLedName); typedef int (*LPMLAPI_GetLedInfo)(BSTR type, DWORD index, BSTR* pName, SAFEARRAY** pLedStyles); typedef int (*LPMLAPI_GetLedColor)(BSTR type, DWORD index, DWORD* R, DWORD* G, DWORD* B); typedef int (*LPMLAPI_GetLedStyle)(BSTR type, DWORD index, BSTR* style); typedef int (*LPMLAPI_GetLedMaxBright)(BSTR type, DWORD index, DWORD* maxLevel); typedef int (*LPMLAPI_GetLedBright)(BSTR type, DWORD index, DWORD* currentLevel); typedef int (*LPMLAPI_GetLedMaxSpeed)(BSTR type, DWORD index, DWORD* maxLevel); typedef int (*LPMLAPI_GetLedSpeed)(BSTR type, DWORD index, DWORD* currentLevel); typedef int (*LPMLAPI_SetLedColor)(BSTR type, DWORD index, DWORD R, DWORD G, DWORD B); typedef int (*LPMLAPI_SetLedColors)(BSTR type, DWORD AreaIndex, SAFEARRAY** pLedName, DWORD* R, DWORD* G, DWORD* B); typedef int (*LPMLAPI_SetLedColorEx)(BSTR type, DWORD AreaIndex, BSTR pLedName, DWORD R, DWORD G, DWORD B, DWORD ); typedef int (*LPMLAPI_SetLedColorSync)(BSTR type, DWORD AreaIndex, BSTR pLedName, DWORD R, DWORD G, DWORD B, DWORD ); typedef int (*LPMLAPI_SetLedStyle)(BSTR type, DWORD index, BSTR style); typedef int (*LPMLAPI_SetLedBright)(BSTR type, DWORD index, DWORD level); typedef int (*LPMLAPI_SetLedSpeed)(BSTR type, DWORD index, DWORD level);

提前感谢

看起来像是

SAFEARRAY

存在于

oaidl.h

中，它需要在

MysticLight_SDK.h

之前包含（以及在使用C++中的

MysticLight_SDK.h

时通常包含的任何其他头文件）

PyPyy以预编译头的形式将标准C++标题拉入，但任何其他平台和项目头都需要显式地包含，或者需要打包成单独的字典（）以允许自动加载。 更准确地说，使用上面链接的.zip文件，可以执行以下操作：

import cppyy
cppyy.include("oaidl.h")                  # <-- this is the one
cppyy.include("MysticLight_SDK.h")
cppyy.load_library("MysticLight_SDK_x64")

导入cppyy
cppyy.include（“oaidl.h”）#“rootcling-f myclass_rflx.cxx myclight_SDK.h”在我的命令行上执行了此操作，但在输入_line_9:27中包含的文件中得到了与上面相同的错误。/mycling_SDK.h:7:38：错误：未知类型名称“SAFEARRAY”typedefint（LPMLAPI_GetDeviceInfo）（SAFEARRAY*pDevType，SAFEARRAY**pLedCount）;''' 我对这类事情还不熟悉，而你看起来像是能在这方面帮助我的人。请你好心地指导我完成这件事。谢谢你是CPPYY的作者。在你面前感到很幸运。我从没想过像你这样的大人物也会使用stackoverflow，我知道你可能没有太多的空闲时间，但我希望你能回答这个问题，所以我会给出一个更好的描述sdk文件夹有3个文件1个头文件和2个Dll文件，我想调用这些函数，获取它们将返回的值，并使用这些头文件执行一些功能一个新值。对于字典，我的意思是打包
oaidl.h
，以便自动找到它。要在字典中打包
MysticLight_SDK.h
，需要以与交互提示相同的方式包含
oaidl.h
。我已经用一个基本的代码示例更新了上面的答案，但是我真的不知道如何使用SDK头，因为它不包含任何API，所以肯定还有其他内容。
import cppyy
cppyy.include("oaidl.h")                  # <-- this is the one
cppyy.include("MysticLight_SDK.h")
cppyy.load_library("MysticLight_SDK_x64")
