我正在尝试构建 RegFS sample更好地了解 Windows 投影文件系统。我的代码在没有警告的情况下构建，但出现动态链接错误。下面是一个错误示例，下面是导致该错误的代码。
“无法在动态链接库中找到过程入口点PrjWritePlaceholderInfo。”
HRESULT VirtualizationInstance::WritePlaceholderInfo(
LPCWSTR relativePath,
PRJ_PLACEHOLDER_INFO* placeholderInfo,
DWORD length
) {
return PrjWritePlaceholderInfo(
_instanceHandle,
relativePath,
placeholderInfo,
length);
}
我确信我在链接时做错了什么。在 [项目属性页] > 链接器 > 输入下，我将“ProjectedFSlib.lib”添加到“其他依赖项”前面。
这是我第一次使用默认情况下未链接的库的 Visual Studio，并且我无法找到有关如何在 Windows SDK 中查找和链接库的说明。
感谢您的帮助!

很明显，它从 PROJECTEDFSLIB.dll 导入所有必要的函数
最佳答案
将 ProjectedFSLib.lib 添加到您的库中或添加:
#pragma comment(lib, "ProjectedFSLib.lib")
代码中的行。另外，请确保您使用的 SDK 版本为 10.0.17763.0。如果您正在使用 mingw，如果这个库尚未可用，我不会感到惊讶。
