 | Linux | ''bin/lord'', ''bin/lordcfg'': native x86-64 programs, statically linked. | Free Pascal 3.2.2 for Linux. |

-The code that differs is inside ''{$IFDEF MSDOS}'', ''{$IFDEF WINDOWS}'' and their ''{$ELSE}'': the DOS side talks to a COM port (''doordos.inc''), the Linux side to stdin/stdout (''doorunix.inc''), the Windows side to pipes (''doorwin.inc'').

 </code> This makes ''bin-dos/lord.exe'', ''bin-dos/lordcfg.exe'' and ''bin-dos/LORDFP.STR''. Copy them into the LORD directory as ''LORD.EXE'', ''LORDCFG.EXE'' and ''LORDFP.STR''. Built this way they are identical to the ones in LORDFP.ZIP.
 Steps 1-4 are only needed once.
+===== The Windows version =====
+Free Pascal for Linux cross-compiles to Windows with its own linker; it only needs the x86_64-win64 units, built once from a clean Free Pascal 3.2.2 source (not the one patched for DOS):
+<code bash>
+git clone --depth 1 --branch release_3_2_2 https://gitlab.com/freepascal.org/fpc/source.git fpcsrc-win64
+cd fpcsrc-win64
+make all OS_TARGET=win64 CPU_TARGET=x86_64 FPC=ppcx64
+make crossinstall OS_TARGET=win64 CPU_TARGET=x86_64 FPC=ppcx64 INSTALL_PREFIX=$HOME/fpc-win64
+</code>
+Then, in the source directory, ''make windows'' makes ''bin-win/lord.exe'' and ''bin-win/lordcfg.exe'' (''make windows WINUNITS=...'' if the units are elsewhere). Test the DOOR32.SYS socket mode on Windows: Wine doesn't let a program use a socket handle it inherited.
