The gnulib config.log has this ...

Should windows.h or something like that be included?

I don't know the answer to this, but I'd suggest looking to see if
there are any reports of this problem to gnulib.
gdb doesn't actually use bcrypt.h at all, this is just pulled in
via gnulib for its getrandom module, AFAICT.

Hmm, something must be different on my system, I don't see this link error on

I fond nothing specifically related. There was some chat related to emacs a
year or so ago but I could not see anything specific.

Thanks. I think the reference is internal in the `tempfile` call or something
like that.

Oh interesting and thanks. It is good to know it can be built.
Is this a mingw gdb or an msys gdb?
We are building with:
../sourceware-mirror-binutils-gdb-fc9b4c8/configure --build=x86_64-w64-mingw32
--host=x86_64-w64-mingw32 --target=sparc-rtems6 --verbose --disable-nls
--disable-gas --disable-binutils --disable-ld --disable-gold --disable-gprof
--with-system-readline --without-included-gettext --disable-win32-registry
--disable-werror --disable-sim --without-zlib --with-expat --with-guile=no
--with-python=/mingw64/bin/python2 --prefix=/d/opt/rtems/6
--bindir=/d/opt/rtems/6/bin --exec-prefix=/d/opt/rtems/6
--includedir=/d/opt/rtems/6/include --libdir=/d/opt/rtems/6/lib
--mandir=/d/opt/rtems/6/share/man --infodir=/d/opt/rtems/6/share/info
I will try building a mingw gdb not crossed to RTEMS.

I can't check the exact build flags right now but I'm pretty sure it was just
disabling binutils/ld/etc. Definitely no host/target flags.

I think this is a similar issue as in PR26068, in that it only happens with gcc
using a mingw-w64 built with --with-default-win32-winnt=0x601 (win7), because
then gnulib sets LIB_GETRANDOM='-lbcrypt', though I'm not sure how gdb should
now about this.
Also if this is really the problem, I'm surprised this wasn't noticed earlier,
because I thought the msys2 build of gcc also defaults to win7.

I also encountered this bug while compiling GDB 10.2 on Linux, with GCC 11.2 &
mingw-w64 9.0.
In my build I noticed that `-lbcrypt` was not present at all on the linker
invocation line.
Adding `-lbcrypt` to LIBS did not help, since the library must be located later
in the list of libraries.
My initial workaround was to patch configure, but later I found a less
intrusive hack, by adding it as DEBUGINFOD_LIBS, which is placed at the end of
the list:
export DEBUGINFOD_LIBS="-lbcrypt"
I think that configure needs to be fixed to do this automatically, probably if
it detects the presence of `bcrypt.h`.

Having a check for -lbcrypt seems completely fine to me,
though I wonder if gnulib ought to be doing this, since this
isn't really a direct dependency of gdb.
Anyway it requires someone experiencing this problem to write a patch,
and/or send a bug to gnulib.
