1 =nt/INSTALL.w64= provides detailed instructions for compiling Emacs on 2 recent Windows versions. Here are some additional steps I had to 3 figure out on my own: 4 * Mingw-w64 5 - Set =$HOME= to =%HOMEPATH%= by changing =db_home= to =windows= in 6 =c:/msys64/etc/fstab=. 7 - In addition to =c:\msys64\mingw64\bin=, adding =c:\msys64\usr\bin= 8 to the system =PATH= allows Emacs to access applications installed 9 with =pacman=. 10 - It's not obvious whether the Mingw-w64 =PATH= entries should go 11 last (in which case Emacs will pick the wrong ~find~ command) or 12 first (in which case… /everything else/ will pick the wrong ~find~ 13 command?). At least Emacs has a variable to configure 14 (~find-program~). 15 * Compiling 16 Make sure to specify ~-c core.autocrlf=false~ *when cloning* the Emacs 17 repository; ~autogen.sh~ gets confused otherwise. 18 * Configuring 19 AFAICT one must set the variable ~shell-file-name~ explicitly to 20 =c:/msys64/usr/bin/bash.exe=, otherwise Emacs's Windows-specific 21 initialization logic uses a built-in shell ersatz (=nt/cmdproxy.c=). 22 ** TODO =HOME= 23 Went with the instructions from [[info:emacs#MS-Windows Registry]]; could 24 maybe use [[info:emacs#Windows HOME]] by setting =HOME= to =%HOMEPATH%=, 25 to avoid having to spell out my username?
