I wanted to try building purgatorio (inferno) on a Windows system, and with some effort I got it compile using Visual Studio. Even more than that, I was able to set up Visual Studio in a way that I can use IntelliSense and the debugger.

Here are a few notes:

• make sure that git doesn't change line endings to CRLF! This is important!
  • to "fix" files later, change the file and use git restore to restore it after setting git config core.autocrlf false
• it's easiest to open folder in VS, then open the programmer command line. This sets up %PATH% etc.
  • Tools → Command Line → Developer Command Prompt
• Do not try to run makemk.sh etc. Just use the NT binaries that are shipped with the repo (Nt/386/bin).
• adjust mkconfig
• set %PATH% to include Nt/386/bin: set PATH=%PATH%;...
• mkfiles: cl/link/lib args replace - with / — mostly optional
  • the tools sometimes print warnings that the dash options will be deprecated. I think for the future we should change the mkfiles for Nt. / is the windows way for options.
• libinterp: first manually mk *.h (individual headers)
• utils/mkfile: windows can't build mk properly:
  • multiple arguments are bundled to a single argument, which can't be understood by cl
  • mk is already built and likely won't change, so you can just comment out mk in the mkfile (NOTPLAN9)
  • I assume the issue is this line: CFLAGS=$CFLAGS -I../include -DROOT'="'$ROOT'"', and $CFLAGS is included as a single option, not a list of options.
