compilation error String vs Text

[kpbochenek]

I am hitting compilation error:

gtk-sni-tray/src/StatusNotifier/Tray.hs:72:37: error:
    • Couldn't match expected type ‘[Char]’ with actual type ‘T.Text’
    • In the first argument of ‘pixbufNewFromFile’, namely ‘name’
      In the second argument of ‘(<$>)’, namely ‘pixbufNewFromFile name’
      In the expression: Just <$> pixbufNewFromFile name
   |           
72 |     then Just <$> pixbufNewFromFile name
   |                                     ^^^^

Tried with OverloadedStrings but suprisingly didn't help, any idea what could cause that?

Changing to then Just <$> pixbufNewFromFile (T.unpack name) solves issue for me, but does current version on master compiles for you?

Current version definitely compiles for me, and if you look at the docs, they indicate that the correct type is T.text (see https://hackage.haskell.org/package/gi-gdkpixbuf-2.0.15/docs/GI-GdkPixbuf-Objects-Pixbuf.html#v:pixbufNewFromFile). A lot of people do seem to be having this issue (See #1). I believe @dongcarl is also seeing this.

@garetxe Might be able to help. You can usually reach him in the gitter haskell-gi chat.

My understanding of all of this is not super solid, but there are three possible causes of this that I can think of:

1. The haskell-gi build tool that you have installed is too old (or something else is going on with the haskell-gi version)
2. The actual gir files (gtk/gdk version) that you have on your machine are somehow outdated haskell-gi uses these to generate the code for the relevant libs
3. The version of gi-gdkpixbuf is cached in your .stack-work as an older version, and needs to be rebuilt.
