[wxhaskell-devel] Compiling the sources with ghc-6.6.3

[Mads L. <mad...@ya...>]

Hi all

I've been trying to compile WxHaskell with GHC 6.6.3, as this is the
stable version in Debian. I know I should have done this regularly, but
I have unfortunately been getting into the bad habit of only compiling
with GHC 6.8.1 and GHC 6.8.2.

First of all, I assume that if people want to compile with old versions
of GHC, they will have to live with using the Makefile version. E.g.:

chmod 755 configure
../configure --with-opengl --prefix=/usr/local/
make
....

Luckily, it all went nicely except for this patch:

"Sun Aug 19 22:42:30 CEST 2007  shelarcy <she...@gm...>
  * Use Data.Time.getCurrentTime instead of (System.)Time.getClockTime
  to avoid build failure by generated non-UTF8 String"

The problem is that the module imports Data.Time, which do not exist in
GHC 6.3.3. If I uncommit the patch everything compiles. And the examples
in samples/wx runs - the two I tried anyway.

Anyway, my question is, how do we remove this dependency on Data.Time
for GHC 6.6 only, without forcing GHC 6.8 users to also not use
Data.Time?

Also, do other people compile with GHC 6.6? Or is it just me who have
to, because Debian's is so out of date.

Would it be fair to ask people to install the time package?
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/time-1.1.2.0

If not, we could conceivably have a ghc-6.6 branch without the patch.

I think 6.6 is pretty common (Ubuntu Gutsy uses it), although I
personally have given up on using the GHC that comes with my system,
and have just gone with whatever packages the GHC folks themselves
provide.

It would be fair, except that the time-package did not compile easily on
Debian either :( I will try to look more into the issue this weekend.
Maybe I could get the time-package maintainers to fix the issue.

But a binary package could just use a version without the patch. This
would be the easiest for people.

Is it really necessary to create a branch for that? Or maybe it is more
trouble than I think. Could we not just ask people to un-record / revert
the patch? It's two darcs commands. And they could just copy'paste them
from the wiki.

With respect to source bundles, I guess we could have two different
ones. One for GHC-6.6 and one for GHC6.8.

I would have thought Ubuntu were a lot more up-to date.


But I must admit I was hoping for some configure-script magic. I have
never edited configure-scripts before and are therefore quite ignorant
of what is possible. Or how to do it.

Is this Debian's problem?
Doesn't anyone met get same problem on any other Linux's package system?

I think we have yet another solution.
Adding compilation flag for wxdirect by make and c-preprocesser.

http://www.haskell.org/ghc/docs/6.6/html/users_guide/options-phases.html#c-pre-processor

So, I want to know this problem is common to some Linux's package system.

Hmm, is it perhaps just a matter of upgrading your Cabal?  The new cabal
files aren't compatible with the version that ships by default with GHC
6.6.

You're right.  Even better, it's just one command (obliterate, which
does the same thing as unrecord/revert)

If it helps, our configure script is hand-written and not using
autotools.

It might very well have to do with the Debian stable version of Cabal.
But I would rather give users a source and binary bundle without the
patch, than requiring them to install a new version of Cabal and a new
version of the time-package.
