与Windows Projected File System DLL/LIB链接
与Windows Projected File System DLL/LIB链接
提问于 2018-12-10 14:53:47
我正在尝试构建RegFS sample，以便更好地理解Windows Projected文件系统。我的代码是在没有警告的情况下构建的，但是我得到了动态链接错误。下面是一个示例错误，代码就在下面导致它。
“在动态链接库中找不到过程入口点PrjWritePlaceholderInfo。”
HRESULT VirtualizationInstance::WritePlaceholderInfo(
LPCWSTR relativePath,
PRJ_PLACEHOLDER_INFO* placeholderInfo,
DWORD length
) {
return PrjWritePlaceholderInfo(
_instanceHandle,
relativePath,
placeholderInfo,
length);
}我确信我在链接的时候做错了什么。在项目属性页>链接器>输入下，我将"ProjectedFSlib.lib“前置为"Additional Dependencies”。
这是我第一次在Visual Studio中使用默认情况下未链接的库，我一直无法找到有关如何在Windows SDK中定位和链接库的说明。
谢谢你的帮忙!

可以将ProjectedFSLib.lib添加到库中，也可以添加：
#pragma comment(lib, "ProjectedFSLib.lib")代码中的代码行。另外，请确保您使用的是10.0.17763.0版本的SDK。如果你正在使用mingw，如果这个库还没有发布，我也不会感到惊讶。
