I am building the firmware through the Custom Builds website (https://nodemcu-build.com/)
Using all default libraries + U8G2
I'm able to upload the firmware generated without any problems.
Then just add a simple Lua example (ESPlorer) and the compiling fails.
attempt to call field 'ssd1306_i2c_128x64_noname' (a nil value)
I've flashed just the loader firmware all fine.
Then reload the custom one, and same error.
As a side note, I've built many other projects in Lua/ESPlorer with success, is just this U8G2 library I can't get to work.
