Link 项目 ntdll.dll 在 Visual Studio

Question

我尝试使用 Visual Studio 构建 lmdb，但出现以下错误：

mdb.obj : error LNK2001: unresolved external symbol _NtMapViewOfSection@40
mdb.obj : error LNK2001: unresolved external symbol _NtClose@4
mdb.obj : error LNK2001: unresolved external symbol _NtCreateSection@28

对于此函数在代码中的首次使用，有以下评论：

/* We use native NT APIs to setup the memory map, so that we can
 * let the DB file grow incrementally instead of always preallocating
 * the full size. These APIs are defined in <wdm.h> and <ntifs.h>
 * but those headers are meant for driver-level development and
 * conflict with the regular user-level headers, so we explicitly
 * declare them here. Using these APIs also means we must link to
 * ntdll.dll, which is not linked by default in user code.
 */
NTSTATUS WINAPI
NtCreateSection(OUT PHANDLE sh, IN ACCESS_MASK acc,
  IN void * oa OPTIONAL,
  IN PLARGE_INTEGER ms OPTIONAL,
  IN ULONG pp, IN ULONG aa, IN HANDLE fh OPTIONAL);

我如何在 Visual Studio 中 link ntdll.dll？我明白了，这个问题很愚蠢，但我无法在几个小时内找到解决方案..

Answer 1

您可以 link 在 Visual Studio 中使用 ntdll.lib。

Answer 2

非常感谢@datjko！他是对的：

I believe the version number in trunk was not updated by mistake. Version 0.9.17 was released in Nov 30, 2015 and is available here github.com/LMDB/lmdb/releases/tag/LMDB_0.9.17. As far as I can see, using of functions from ntdll was added to trunk after the release in github.com/LMDB/lmdb/commit/… also in Nov 30, 2015. So, unless you want to testdrive the recent development version I believe you'd better use a recent stable version.

按照他的建议问题解决了。
