@RynoRoe What errors do you get when installing the package ?

RynoRoe · 15 Jan 2025, 19:31

@mitu it gives me this error:
Could not successfully install dbargun - dbargun is a Linux userspace driver for the wiimote with DolphinBar support.
(opt/retropie/supplementary/dbar4gun/bin/dbar4gun not found).

The previous messages are showing the actual error. Try to post them also, along with the your setup info as requested in https://retropie.org.uk/forum/topic/3/read-this-first.

@mitu ok I’m running the newest install of retropie on a pi3 while running usb rom service with all my roms on an external drive. Here is the log file text:

OK, I see the error. Should be fixable - I'll take a look at it.

EDIT: it seems the new code is not compatible anymore with RaspiOS Buster and needs Python 3.8 as a minimum.

@lowlevel1989 we can install the 0.13 version for older RaspiOS, before the calibration code was added - is that ok ?

RynoRoe · 17 Jan 2025, 03:22

@mitu so does this mean I need to somehow install an older version of dbar4gun?

mitu · 17 Jan 2025, 04:18

@RynoRoe At the moment, yes.
You can try this version of dbar4gun.sh which you can replace the $RetroPie-Setup/scriptmodules/supplementary/dbar4gun.sh and re-try the installation. Make a backup of $HOME/RetroPie-Setup first, before replacing the file, and restore it afterwards.

zipstick · 29 Jan 2025, 11:35

Hi, im really curious about this and wanting to try it out. If i understand correctly this will enable you to use two lightguns simultaneously? I have retropie setup on a Pi400 which only has 3 USB ports, and all mine are currently in use (2 controllers+ mouse). Would this work with the Dolphinbar connected through a USB dongle?
@RynoRoe did you get this working with the older version ?

mitu · 4 Feb 2025, 16:32

@RynoRoe the installation should work now without futher modifications, just update RetroPie-Setup and re-try the installation.

Chef Otis · 17 Feb 2025, 16:18

@mitu

I get the same errors as @RynoRoe , just on a rpi4 4.8.9

Are you fully up-to-date ?

Chef Otis · 17 Feb 2025, 18:52

@mitu Yessir, always up to date and official

mitu · 17 Feb 2025, 19:03

@Chef-Otis Please post the exact error message. The latest version shouldn't have that error anymore.

Chef Otis · 17 Feb 2025, 20:40

@mitu ah yes, I see it now

The virtual environment was not created successfully because ensurepip is not
available. On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

apt-get install python3-venv

You may need to use sudo with that command. After installing the python3-venv
package, recreate your virtual environment.

@Chef-Otis you have the latest version indeed, bu the error is puzzling since the package's dependencies specifically install python3-virtualenv and python3-dev. I can't reproduce it here.

What's the output of the locale -a command ? Did you change the system/user language ?

Chef Otis · 1 Mar 2025, 11:18

@mitu

pi@retropie:~ $ locale -a
C
C.UTF-8
en_GB.utf8
POSIX

this is what I get with that command. I don't think I've change any sort of system/user language..

After applying apt-get install python3-venv I was able to install dbar4gun successfully, but I still can't actually get the wiimote working.

lowlevel1989 · 1 Mar 2025, 11:18

@Chef-Otis, have you followed the steps in the README? Were you able to start the service, or what issue are you facing exactly?

I usually respond faster when the error is reported through this channel: GitHub Issues.
