Thanks for the output, the Verbose switch is on the vMicro > Compiler Menu, 3rd item down from the top.  If you can enable this as well and post the full output again it will help.

Can you provide a simple code example (or a link to one if it is from an online source) which replicates the problem so we can investigate fully?

Thanks for the logs and sketch, can you confirm where you have downloaded the LiquidCrystal_I2C v1.0.0 Library from?

Thanks for the location.

The error is coming from the buckotest code files in your project which are commented out in the example provided.

Does your sketch compile with those files removed (or a new project with just the code provided as an example in)??

Thanks again.   ok deleted buckotest.h and buckotest.cpp, cleaned then built gain.   Got past last errors but now have new ones.   Output attached.

BTW:  in VSCode i would have a main.cpp then my configs would be in config.h and config.cpp .

In VM have a SketchName.ino then my configs would be in config.h and config.cpp ,  is this correct?

The only error in the log I can see is at the end, and this is a problem in the Arduino IDE as well:
# Failed to export binary and merge the bootloader (hex): no colon char on the first line character

This generally can be ignored unless you require the merged binary including the bootloader specifically, in which case the board package creator should be consulted.

You are correct about the configs.h/cpp being referenced from the INO in an Arduino compatible project.
