My tkd GUI app started getting compiled with an outdated 8.5 Tk framework version which gets shipped with command line tools: xcode-select --install. As a result, the UI doesn't display icons and is laggy. When you run the compiled tk app, you get a notorious warning:

DEPRECATION WARNING: The system version of Tk is deprecated and may be removed in a future release. Please don't rely on it. Set TK_SILENCE_DEPRECATION=1 to suppress this warning.

This didn't happen before but here is why it probably started to occur.

I've recently been playing with uninstalling the MacPorts in favour of homebrew and in the process I had to remove tk8.6 library which was installed once by MacPorts. I wasn't aware that command line tools come with their own version of tk which is 8.5. Somehow, after moving to homebrew, I rebuilt the app and saw new warnings that never appeared before:

../../../../.dub/packages/tkd-1.1.13/tkd/source/tkd/image/png.d(83,7): Deprecation: Function `tkd.image.image.Image.embedBase64Data!("lock.png", EmbeddedPng!"lock.png").embedBase64Data` of type `@system EmbeddedPng!"lock.png"()` is not accessible from module `png`

I tried coming back to MacPorts, reinstalling the command line tools reinstalling the tkd and dub dependencies but nothing worked so far. Maybe someone here has experience how to make clang go and link against the tk 8.6 version installed by MacPorts instead of 8.5. That would be of great help.

If anyone bumps into this issue. The reason why it happened was because I uninstalled Mac Ports and lost pkgconfig package. When this package is installed on the system, dub uses it to resolve the necessary flags and links with -L-ltk8.6 -L-ltkstub8.6 -L-ltcl8.6 -L-ltclstub8.6 instead of 8.5.

Keep in mind that in order for your tkd app to work on Mac OS, you need to install quartz type of tk: sudo port install tk +quartz. After that your should be able to run the app.
