in str.h，#include <c-ctype.h>，where can i find this file about gnutls

You need to properly initialise the gnulib submodule.
From the gnutls folder execute 'git submodule update --init'

there are nothing in "gunlib",how can I find such XX.c

[Sibras]

c-ctype.h is found in the "gnulib\lib" sub folder. This folder only exists if you initialise submodules as mentioned above

when compile the files under the gnutls\lib\accelerated\x86 folder, a lots of error like

#include <nettle/sha.h>
#include <nettle/macros.h>

can not find the headers, I have to copy these files from nettle to the gnutls\lib\nettle folder.
Why is that? and am I doing it right?

nettle is a dependency of gnutls you must have already compiled nettle. If you havnt already got nettle then just run the get_dependencies.bat script which will get the required dependencies. Then just open the gnutls_deps.sln which includes all dependencies and will build them for you.

Note: There is a readme in the SMP folder that explains all this.

Sorry，I‘ve already complied nettle under folder D:\FFMPEG_PROJECT\nettle\SMP by running libnettle_deps， it succeeded.
And I also have ran the get_dependencies.bat under folder D:\FFMPEG_PROJECT\gnutls\SMP, but I still can not compile libgnutls_deps.sln, the errors are cant't find those files：

#include <nettle/sha.h>
#include <nettle/memxor.h>
......

Based on your folder structure when compiling nettle it should have created the required headers in D:\msvc\include\nettle.
