Creating a library... resources not found

I am trying to make a library to ‘hold’ the Custom LED/LCDs..
The views in staging work and I am building without error.
I copy the xojo_library from the build folder to the project folder of another project

It shows up in the list of plugins…

However when i try to run the project (without even having referenced the new library yet i get this error message:

LCD55X81Display.Super
Can't find a type with this name
BitmapLCDFont

I guess it’s about what ‘needs’ to be put into the Library folder of the library project?

Does ‘everything’ except app, menu and window belong in the library?

I doubt resources are embedded into libraries. Try adding the resources into your other project with the exact name, same folder location, and it might compile.
If not you will need to move to loading the files from a resources folder and setting the references in code via the library .
