I want to build sdcc for NMK322 so that my students can use EXACTLY what I have. So, here we go again:

Installing MinGW:

• Get the 'package manager' from here
  • version 0.6.3 (beta) at the moment
  • I prefer the standalone binary (no setup)
• Pick a location and extract the zip file
  • I choose C:\Users\Public\Tool
  • change the folder name so that we have C:\Users\Public\Tool\mingw\bin\mingw-get.exe
• Prepare to use mingw-get binary
  • cd C:\Users\Public\Tool\mingw\var\lib\mingw-get\data\
  • copy defaults.xml profile.xml
• Open a command prompt and update catalogue
  • cd C:\Users\Public\Tool\mingw\bin\
  • mingw-get.exe update
• Get stuffs (compiler with Unix-like environment) without using GUI
  • mingw-get.exe install gcc g++ gmp mpfr mpc msys msys-wget-bin
• To get GUI interface install mingw-get (apparently, we are NOT running mingw-get! )
  • mingw-get.exe install mingw-get
  • now, a window will come up when you run mingw-get

Note20220808 Current software versions {gcc:9.2.0,binutils:2.32}

Some useful things to do:

• To have git in MinGW shell, install Git-for-Windows at C:\Users\Public\Tool\Git
  • edit C:\Users\Public\Tool\mingw\msys\1.0\etc\profile and insert

    MY1GITPATH="/c/users/public/tool/git/bin"
    [ -d "$MY1GITPATH" ] && PATH="$MY1GITPATH:$PATH"

    before the block containing an export PATH line(s)

• Get helper script(s) - I wrote that for personal use
  • copy everything (except LICENSE, README.md and msys2.vbs) to C:\Users\Public\Tool\mingw
  • allows environment to be used on shared computer (no need for admin account)
• Running msys.vbs (*Hint*: double-click) will install (or remove if already installed) a pop-up context menu entry (MinGW Shell) whenever you right-click on a folder in Windows Explorer
  • edit C:\Users\Public\Tool\mingw\msys\1.0\etc\profile and comment (place '#' at the beginning of) the last line with cd $HOME command
• If you want to use normal Windows command prompt to run stuff, these two scripts are you friend (you may ignore them otherwise)
  • Running mingw-setup.bat sets up normal command prompt for command-line compilation
    • place mingw-term.bat script (form tools folder) in any folder - when executed, it will open a command prompt (with MinGW path properly configured) in that folder
  • Running mingw-clear.bat cleans up settings created by mingw-setup.bat
