Summary

go build failed: undefined: gosseract.NewClient when CGO_ENABLED=0

CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build main.go
main.go:10:22: undefined: gosseract.NewClient

If I change CGO_ENABLED to CGO_ENABLED=1 then will get other errors:

CGO_ENABLED=1 GOOS=linux GOARCH=amd64 go build main.go

This works for me

CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o out .
