Hi
(Windows11 23H2)
nmake /f Nmakefile
produces the following error (photo 1.png)

Look at line 31 in Nmakefile
!IF DEFINED(PLATFORM)
I checked the value of PLATFORM
!MESSAGE Platform is $(PLATFORM)
and got x64 (not x86-64).
As far as I understand, line 62 is executed next (and no factor.com is created)
I tried the following
nmake /f Nmakefile x86-64
factor.com appears, but bootstrapping gives an error (photo2.png)

The same error is given by the following combination

build.cmd compile
build.cmd update-boot-image
build.cmd bootstrap

look at lines 68-74 in build.cmd
Interestingly, the following command works well
build.cmd (or "build.cmd update")
The only difference I see is that there is no "call git pull" in the previous case.
