So many errors with newer libs

[Stig2k]

Had a scroller working for years then damaged the D1 it was running on. Downloaded the latest version from here then installed the IDE and the needed libraries. So many errors and warnings!

Does anyone know what older versions of required libraries might get this project working again?

What board did you select and what version of ESP8266 core are you using. You should be able to use latest on most library files.

Edit: looking at it closer it looks like it is probably related to your TimeDB library -- use the library manager to install that for the IDE and don't extract it manually. Give that a try.

[Stig2k]

Thanks, I've gone through the library manager and installed all four versions of Time (Michael Margolis) but get the same result each time.
I really really wish I'd kept a backup of my sketch folder before getting my new PC!

[Qrome]

The compiled binaries are available in the download as well.

Edit: Also, this line in your error makes me think you have a conflict and I don't know why you have the library installed here: c:\Users\simon\Documents\Arduino\marquee-scroller-master\libraries\Time/TimeLib.h:78: note: this is the location of the previous definition

[Stig2k]

To be honest neither do I!
I'm doing the best I can with YouTube tutorials, but this is confusing as hell for me.
However, I dug out an old Win10 laptop I have and found a backed-up arduino library directory in my One drive. Long story short, I downloaded and installed an older Arduino IDE (1.8.18) and have been able to compile and upload to a replacement WeMos board.
It's only today that I've realised that there is the sketch location parameter which I think means you can have various versions of libraries available to different projects.
Thanks for your help btw

[Stig2k]

Is it possible for me to compile a single file now that I know I'll be able to write to another WeMos in the future if I should need to? Rather than (potentially) having to track down all manor of libraries and versions of things in the future.

[MintsGit]

did you ever fix this? I have same error message
