problem with cabal install #48

Closed haihan-yu closed 1 year ago

haihan-yu commented 9 years ago

Hello I know HLearn from your blog, HLearn is really an exciting project. But I encount some problem when I try to install HLearn from cabal. My GHC version is: version 7.8.3. My operating system is Mac OSX 10.10.2. The following is the error message I get. Thanks a lot! $ cabal install HLearn-algebra-0.0.1 Resolving dependencies... Configuring HLearn-algebra-0.0.1... Building HLearn-algebra-0.0.1...

I think your problem comes from constraintkinds 1.3.0 being incompatible with HLearn-algebra. As far as I know only in the latest version of HLearn-algebra is the dependency constraint set to not allow constraintkinds 1.3.0. Try installing the latest HLearn-algebra instead. Then likely you will run in to this problem Issue 44

Restricting the version to 1.1.0.0 does not work because ConstraintKinds doesn't build properly:

HLearn-algebra-1.1.0.0 depends on ConstraintKinds-1.1.0.0 which failed to
install.

I noticed constraintkinds has been deprecated. Is Hlearn going to be updated to use subhask?

mikeizbicki commented 9 years ago

The version on github uses subhask. There are a LOT of improvements, but it'll be a while before it is ready for a proper release onto hackage.

boersmamarcel commented 9 years ago

I've got a similar problem, I'm currently using Mac OS X 10.10.3 with ghc 7.8.3 and tried the quick and dirty installation guide however without succes.

I'm using the antipolymorphism branch of HLearn with subhask from the git repository.

I currently get

How can I solve this? I'd love to try HLearn

That guide was wrong. I've updated it with the correct commands.

Be forewarned that the documentation once installed is very sparse, so don't get your hopes too high on doing too many useful things with it yet.

Thanks for the help :) I tried the new quick and dirty install guide but it didn't work. The build still hangs on 

JuicyPixels-3.2.3.1 failed during the building phase.

However, after some google work I stumbled upon the following:

sudo ghc-pkg recache

and then the cabal build gave some error like

src/HLearn/Data/SpaceTree.hs:61:8:
    Could not find module ‘HLearn.Models.Distributions.Univariate.Normal’

worked my way through by commenting out the specific lines but then trying to import the files does not work anymore.

Yesterday I was in the process of converting the repo to work with GHC 7.10, and I didn't quite finish. So the latest commit might break some stuff. Sorry about that. I should have been working in another branch.

Try running

git checkout master~1

and see if that works.

@aibrahim You either need to use the ghc7.10 branch or run checkout master~1 (see the comment above for more details).
