Re: [wxhaskell-devel] Building wxcore on Ubuntu 10.04

[Dave Tapley]

I have done some further investigation on this and discovered the source of
the problem, and it is very strange.

It seems that even in the latest 2.8.12 release of wxWidgets¹ the cursor.h
file in include/wx/gtk/ does not contain the four argument constructor
(which is causing the build failure below), however the cursor.h in
include/wx/msw does.

I looked at the history for eljcursor.cpp in darcs and it hasn't been
changed in anyway in a long time, so this can't be a new problem.

I am going to post to the wx-dev² group and see if anyone knows why this
constructor declaration is missing.

But the question remains:
How have we been able to build wxcore for GTK when its .cabal claims³ it
works for GTK with wxWidgets 2.8?

Thanks,
Dave

Hmm, unfortunately whilst cabal configure now completes successfully, I am
having a problem when doing cabal build, see output below. Could it be
related to this:
