[Gtk2hs-users] gtkglext build problem

[David D. <D.J...@le...>]

ghc 8.6.3
cabal 2.4.1

I installed gtk fine using cabal install,  it gave me version 0.15.2

However when I tried to cabal install gtkglext it failed due to a  conflict
I manually down loaded the package and looked at the cabal file.
The problem was spears to be the constraint  gtk < 0.15

I could raise this as an issue on the cabal bug-tracker, but before doing so does
Anyone have  a solution or a better experience.. Installing gtkglext?



Thanks,
David
