Sorry, at the moment we don't have any alternative -- the most common alternative option is to use python but the firmware is not written in python so this isn't feasible. At the moment you can still install wiringPi using apt-get install, which is already included in the build.sh script. If they discontinue this in the future, a possible solution is to write a python script that handles gpio functions and have the firmware call the script through a system() call.

Can you please reopen this, wiringpi has indeed been removed from recent versions of raspberry pi os, and not installable via apt.
There are also a number of other libraries available that are worth exploring.

OK, I will keep this open. I suppose you are referring to raspbian bullseye which is the newest version of raspbian. I believe wiringpi is still installable via api on buster. So unless if you must use bullseye, just use buster.

This really is an issue. Even though Debian Buster is a LTS release, it will eventually be deprecated. Enforcing old software to support a library abandoned by its own creator creates a huge technical debt and it will just get worse in time.

As a workaround, you can find .deb archive on the authors web site, just read the blog. I wouldn't count on it for them being available that way for long, though. Anyways, the .deb file seems to work with bullseye.

BTW, ./build.sh ospi tries to install the wiringpi dependency but continues even though the installation failed.

It looks like some people picked it up. Not saying it shouldn't be replaced, but this may help in the interim:https://github.com/WiringPi/WiringPi

Hi there,

now the original wiringPi Website is completely gone. The Library is also not anymore listed in the debian package search debian package search. I tried to install the mirror version which went fine, but i am not sure if the normal compilation did take it up. As @roben pointed out, the build script doesn't even stop compiling Opensprinkler in case the apt install went wrong.

With this stated is it currently even possible to install a new OsPI?

Agreed, WiringPi isn't viable any ore and an alternative needs to be sought.

WiringPi is here available: http://wiringpi.com/download-and-install/
has anyone tested it with bullseye?

No the link is dead. As above, there are only some unofficial mirrors left.

Ugh, I found this because I followed the official installation instructions. I installed default RaspiOS (bullseye, 32-bit), but then the install script couldn't install the wireingpi package.

• Please add a warning to the README.md that this project is not maintained anyomore (and point ppl to possible alternatives)
• Please add a warning to the README.md that you need to use the old version of Raspi OS (buster) (or point to any option how to add wiringpi to bullseye)
• I don't know how to address in inclusion of these warnings in the official installation instructions, but if anyone has a close connection to it, please update them as well.

It's not a great user experience to land in this deprecation hole.

Thanks anyway for this project and I hope maintenance will continue some day!

Btw, this is how I got it installed it on RPi OS bullseye just now:

wget https://github.com/WiringPi/WiringPi/releases/download/2.61-1/wiringpi-2.61-1-armhf.deb
sudo dpkg -i wiringpi-2.61-1-armhf.deb

I found that raspi-gpio command is now available in the latest raspbian and that can replace wiringPi for turning on pull-up/pull-down of any GPIO. This will be integrated into the next version of the firmware.

Awesome, thanks!

This fix has been integrated into 2.1.9(11). I tested it on my RPi 0 W, which seems to work. I don't have any newer RPis for testing due to the ongoing shortage, but I am hopeful that it should work for all RPis running Bullseye.
