我之前知道这个问题,我的CPP文件是:
#include <shlobj.h>
int main(int argc, char *argv[])
{
PWSTR pszPath;
HRESULT hr = SHGetKnownFolderPath(&FOLDERID_Startup,0,NULL,&pszPath);
}
而且我正在使用Linux Mingw编译器通过此命令为Windows编译它:
i686-w64-mingw32-gcc hub.cpp
或
x86_64-w64-mingw32-g++ hub.cpp
我得到:
In function ‘int main(int, char**)’:
error: ‘SHGetKnownFolderPath’ was not declared in this scope
&pszPath);
^
将这些添加到标题无济于事,并且出现相同的错误:
#define WINVER 0x0600
#include <windows.h>
或
#define WINVER 0x0600
#define _WIN32_WINNT 0x0600
并且我查看了[[shlobj.h,并且其中包含SHGetKnownFolderPath。
我该如何解决?编辑
:我的朋友ssbssa]的更改建议在注释中放入#define _WIN32_WINNT 0x0600 before #include <shlobj.h>
,引发新的错误和新的注释:
hub.cpp: In function ‘int main(int, char**)’:
hub.cpp:8:69: error: invalid initialization of reference of type ‘const KNOWNFOLDERID& {aka const _GUID&}’ from expression of type ‘const GUID* {aka const _GUID*}’
HRESULT hr = SHGetKnownFolderPath(&FOLDERID_Startup,0,NULL,&pszPath);
^
In file included from hub.cpp:2:0:

STDAPI SHGetKnownFolderPath (REFKNOWNFOLDERID rfid, DWORD dwFlags, HANDLE hToken, PWST
我可以看到错误说,它期望有一个指针,并且我给了他一个地址,但是我不知道如何以正确的方式声明它。
我知道之前问过这个问题,我的CPP文件是:#include
