Hi I am following lg library installation instructions, but when running "make", I get many errors as below. Am I missing something in the installation. Thanks.

Did you manage to build it?

Looks like you have kernel before v5.10, when gpiochip API v2 was introduced. Actually dropping gpiochip API v1 from lgpio v0.2 it's a problem, becouse a lot of embedded systems use LTS kernel before v5.10.

I make openembedded/yocto recipe for lgpio, and forced to drop last commit before v0.2 becouse of this :(

It's possible to return support of gpiochip API v1?

Use v0.1 if you need API v1.

The only difference between the versions is one uses gpiochip API v1 and the other uses gpiochip API v2.

(the only functional difference is the addition of pulls which are supported in gpiochip API v2 but not in gpiochip API v1).
