Last time I looked, the LLVM debugger didn't work well on Windows, and was definitely not a good idea as a tool to debug Emacs, because it didn't support the .gdbinit commands (which are essential for any reasonable debugging of the Emacs C code), and didn't support GDB/MI (which means you cannot use it with "M-x gdb" from Emacs). Unless this has changed drastically since I looked, my advice to you is to use GDB for debugging the Emacs C code, otherwise you will have a whole additional level of difficulties in making this port happen.

It depends on what would such support require. Judging by what I see in the original report, we are very far from understanding that, so I would withhold my judgment until I see what changes to the existing code are needed to support that configuration. I have no real knowledge of how Clang supports native MS-Windows; I don't even know what they use for the runtime library. So I cannot envision up front what kind of changes will be needed to produce a successful native MS-Windows build of Emacs using Clang.

So you need to find out why in your case it was produced. That's the immediate reason for the failure. I see another problem: MS-Windows builds are supposed to use the cpp option "-I ../nt/inc", to pick up our replacements for missing and incomplete stuff in system header files, and your compilation command above doesn't include that flag. This could be important in this case because we have our own replacement for unistd.h in nt/inc/; the system unistd.h is not supposed to be used at all in the Emacs build on MS-Windows. It is definitely important for the rest of the build. So it sounds like you are not using the build machinery for compiling Emacs on MS-Windows, and if that is intentional, you are up for a bumpy ride, and reporting bugs about this adventure is not necessarily a good idea. You should first make your build process follow the path of MinGW, otherwise many things will break, either vociferously or (worse) silently. > Speaking of configure, it does not even try to locate several libraries. > The string "jpeg", for instance, only appears in config.log as > > LIBJPEG='' So something else is seriously wrong, because on my system I have this: configure:18511: checking for jpeglib 6b or later configure:18555: result: -ljpeg [...] emacs_cv_jpeglib=-ljpeg [...] #define HAVE_JPEG 1 [...] #define EMACS_CONFIG_FEATURES "ACL GIF GMP GNUTLS HARFBUZZ JPEG JSON LCMS2 LIBXML2 MODULES NOTIFY W32NOTIFY PDUMPER PNG RSVG SOUND SQLITE3 THREADS TIFF TOOLKIT_SCROLL_BARS WEBP XPM ZLIB"

Dunno, I use a debugger maybe once every several months, mostly on GNU/Linux, where recent versions of Clang play reasonably well with gdb, or at least not much worse than GCC.

globals.h does not exist. AFAIK it is a generated file, but on this
build it is not generated.
The configure invocation is
configure \
--prefix=/clang64 \
--build=x86_64-w64-mingw32 \
--with-modules \
--without-dbus \
--without-compress-install
Speaking of configure, it does not even try to locate several libraries.
The string "jpeg", for instance, only appears in config.log as
LIBJPEG=''
