[Gtk2hs-users] cairo error: ghc.exe: unable to load package `cairo-0.12.0'

[Daniel <d.k...@gm...>]

Hi list,

I've built gtk2hs successfully for ghc-7.0.2, but if I try to load the example
Drawing.hs from the cairo packages demo folder I get:


*Main> :load Drawing.hs
[1 of 1] Compiling Main             ( Drawing.hs, interpreted )
Ok, modules loaded: Main.

o_image_surface_get_data'
ghc.exe: unable to load package `cairo-0.12.0'

Have tried many things so far:

 * Starting with re-inited package database
 * Doing a $ nm /h/Gtk+/bin/libcairo-2.dll | grep -i cairo_image_surface_get_data
yielding 68de04d8 T _cairo_image_surface_get_data
 * Temporarily renaming libcairo-2.dll (the only one found on my setup, even
not-in-PATH ones are non-existent) yielding as expected "dll not found" error
 * as you can see there is no "literal" space in the gtk+ installation path
(h:\Gtk+), only in the users haskell package installation path, but that's
fairly standard with Windows I guess
 * Compilable with ghc --make ... though, but that's sadly not sufficient as
Chart package isn't installable due to this issue

Greetings
Daniel
