Example code does not work?
Hey, i am getting this
> go build .

Jamesthe12y agoGetting this exact error as well from my own code just by having the inclusion. My go.mod looks like:
module test/nktest
go 1.22.5
require (
github.com/golang-ui/nuklear v0.0.0-20231115163627-2440a671efc5
github.com/veandco/go-sdl2 v0.4.40
)
require (
github.com/go-gl/gl v0.0.0-20231021071112-07e5d0ea2e71 // indirect
github.com/go-gl/glfw v0.0.0-20240506104042-037f3cc74f2a // indirect
github.com/xlab/android-go v0.0.0-20221106204035-3cc54d5032fa // indirect
)and my import looks like:
import (
"log"
"os"
"regexp"
"runtime"
"strconv"
"strings"
"github.com/golang-ui/nuklear/nk"
"github.com/veandco/go-sdl2/sdl"
)Even go install github.com/golang-ui/nuklear/nk simply triggers this error without it being present in imports.
Tried indirects as well, same result.
anibaldeboni2y agoSDL2 example doesn't work either. It seems like the functions are based on some older nuklear api version, the arguments provided in the examples doesn't match the current api.
hajimehoshi2y agoProbably I see the same error.
