(Solved)I have generated a font via font converter but need to know how to use it

Description

What MCU/Processor/Board and compiler are you using?

I am using platformio in vscode to compile for a ESP32-8048S043. I found example code at GitHub - pixelwave/Sunton-ESP32-8048S043: First test with Sunton ESP32-8048S043 + Squareline UI + LVGL + Arduino GFX. I downloaded it and it runs fine. I wanted to use a larger font so I generated a 50 px freesans font. I moved the generated c code to lib/lvgl/src/font. I didn’t know if this belonged in the PlatformIO forum or here, but I decided I’d start here. For some reason, the library dependency finder is using a different library rather than using compiling the files in the lib directory. I add a dep_libs directive to point to file://lib/lvgl but it seems to be ignoring it. Here’s the layout uploaded:
files

What LVGL version are you using?

What ever is in that file.

What do you want to achieve?

I’m trying to add a new font.

What have you tried so far?

Code to reproduce

This isn’t about my code specifically, it’s more of a structural issue. Once I get the library to compile I think I will be able to continue.

Sure it’s not declared 'cause the compile is ignoring the files in the lib directory. I guess I’ve missed some include or didn’t add a line to an existing include but I don’t quite know where to put it.

Thanks,
Jim

Here’s the answer in a nutshell. I had a compiler error, when I corrected that, it got by the error and started compiling the library code. So I fixed a few misspellings/typos to correct a few errors and added an extern statement to let the code know to let the linker find the function. I now have a new font!
