Hi,
I'm trying to install REPA but getting the following. Do I just
install
base? Or is it more complicated than that?
Thanks, Dominic.
I think the easiest solution is to just use an older version of Repa.
According to Hackage, the latest one that works with base 4.3 is Repa
2.1.1.3:
$ cabal install repa==2.1.1.3
I've just pushed Repa 3 onto Hackage, which has a much better API
than the older versions, and solves several code fusion problems.
However, you'll need to upgrade to GHC 7.4 to use it. GHC 7.0.3 is
two major releases behind the current version.
Ben.
Hi Ben, Chris and Others,
Thanks for your replies and suggestions. All I want to do is invert
(well solve actually) a tridiagonal matrix so upgrading ghc from the
version that comes with the platform seems a bit overkill. I think I
will go with Chris' suggestion for now and maybe upgrade ghc (and
REPA) when I am feeling braver.
Dominic.
Sadly I now get this when trying to mulitply two matrices. Is this
because I have two copies of Primitive? I thought Cabal was supposed to
protect me from this sort of occurrence. Does anyone have any
suggestions on how to solve this?

This could be caused by:
* Loading two different object files which export the same symbol
* Specifying the same object file twice on the GHCi command line
* An incorrect `package.conf' entry, causing some object to be
loaded twice.
GHCi cannot safely continue in this situation. Exiting now. Sorry.
