[wxhaskell-users] wxhaskell for new ghc-6.5...

[Patrick S. <mai...@st...>]

Hi to all,

for everyone who isn't involved a short summary:

I try to compile wxhaskell for a very new version of the ghc (the=20
night-release of the 06.02.2005) because the development of HOpenGl is gone=
=20
ahead and I want the new features.
wxhaskell-0.8 crashes when you try to compile. Hopefully just because of th=
e=20
changing options of the new ghc. I "fixed" some of the errors.

The first thing was a depency problem. Daan creates some depency files, her=
e a=20
cut-out from a mail I sent him:

But there were still errors..

I tested a bit around. When the makefile calls the ghc from outside the=20
directory it can't find out the depending modules. So the "ghc -M" call=20
prints this error.
I looked around and saw that the makefile is divided into 3 sections. The w=
x,=20
wxcore and wxd or something like that. I took the variables (WXfoobar-SRCDI=
R)=20
and added them to the searchpath of every "make-hs" call.
That fixed the error problem.

I have the slightly feeling that anyhow somethings are going wrong. The fir=
st=20
one is, that the opengl lib doesn't want to get compiled.. (I added some=20
extra printouts!)

ghc -iout/wxcore/imports/Graphics/UI/WXCore=20

Schluss.

When I compile it without it than i runs through without errors. When I swi=
tch=20
to root to make install the compiling process starts again (ends with=20
failure) and I have no idea why.

Anyhow I tried to compile as root and the install process started correctly=
=20
and ends up with a error from the ghc-pkg programm.
It wants a colon after the first line in the wxcore.pkg.

I hope there are people who are also interested in wx for new ghc and who h=
ave=20
had a closer look to the makefile and the source (not like me:).
I have no idea what I should try next.

Cheers
