Hi,

I'm using the following configuration to setup the package.

(use-package flycheck-posframe     
  :ensure t
  :after flycheck
  :config (add-hook 'flycheck-mode-hook #'flycheck-posframe-mode))

Unfortunately, the following message is depicted: "Package ‘emacs-26’ is unavailable"

I checked M-x package-list-packages and the package is marked as incompat, see bellow:

System Information:

GNU Emacs 25.3.1 (x86_64-w64-mingw32) of 2018-03-05
OS: Windows 10

emacs-26 means you need to be running emacs version >= 26 - but you are running emacs 25.3.1 - so hence why it is incompatible. All these packages use posframe which depends on the childframe functionality which is only in emacs >= 26.
