MS Windows anyone? #168

Open Symbolics opened 4 years ago

Symbolics commented 4 years ago

Has anyone got CLX to work on MS Windows? I get the following error for all values of DISPLAY I tried. Using VcXsrv without any problem with several remote machines. Checked authorisation, etc. No errors reported by the X server. Any ideas?

? (ql:quickload 'clx)
To load "clx":
  Load 1 ASDF system:
    clx
; Loading "clx"

(CLX)
? (ql:quickload 'clx/demo)
To load "clx/demo":
  Load 1 ASDF system:
    clx/demo
; Loading "clx/demo"

Tracking back, it seems to be happening here:

1 > :f 1
 (22D882C8) : 1 (DISPLAY-CONNECT #<DISPLAY 127.0.0.1:0 ( R0)> :AUTHORIZATION-NAME "" :AUTHORIZATION-DATA "") 1629

Hey. Did you check if your environment variables indicate a correct display? I remember someone had an issue where emacs compiled on different machine "saved" the environment variable, so clx couldn't open the display (because on the user machine it was different).

The display from the MSYS2 shell is correct. Any way to check this from within lisp?
