Standalone Longmynd Installation

Hi All,

I'm looking into getting a standalone longmynd installed from (https://github.com/philcrump/longmynd/) on a freshly installed pi. I'm getting the following compilation error thought:

Code: Select all

Hi

Phil's longmynd is not the clean install. He has many other functions in his personal build.

Try this one: https://github.com/BritishAmateurTelevi ... b/longmynd

Hi Dave,

Thanks, but looking specifically to use that version. Also having the same issue with the batc version, so might be on my side. I've got Phil's version working on a linux machine for now for testing. I'll setup a new clean pi and try again :)

Thanks,
Tom

All sorted, looks like best version to use currently is Raspberry PI OS (Legacy) - Buster - 2022-04-04 version

Basic instructions for future reference :)

Code: Select all

sudo apt-get install cmake git make gcc libusb-1.0-0-dev libasound2-dev
git clone https://github.com/philcrump/longmynd.git
cd longmynd && make
sudo cp minitiouner.rules /etc/udev/rules.d/
Thanks!
