Re: happs install seems to have become very slow since upgrading cabal Re: [Haskell-cafe] test driving cabal install...

It did finish, but I still feel like this took too long. 2008/5/29 Thomas Hartman :

sudo cabal install --global HAppS-State went fine, and ghc-pkg had output on just the one (global) file.

but sudo cabal install --global HAppS-Server is slooooooow.

I finally canceled this and did

sudo runghc Setup.hs build -v3 with the same result: extremely, extremely slow compile.

It seems to get hung up one one line:

src/HAppS/Server/Facebook.hs:416:2: Warning: Defined but not used: `a' *** Desugar: Result size = 52971 *** Simplify: Result size = 34350 Result size = 33980 Result size = 33972 Result size = 33972 *** Specialise: Result size = 52989 *** Float out (not lambdas, not constants): Result size = 55269

... and more and more of same. for 15 minutes now. With verbose output on at least I can see there is something going on behind the scenes, but still.

I don't remember things taking this long to compile before I upgraded to cabal v1.4... cabal bug?

cabal --version cabal-install version 0.4.7 using version 1.3.11 of the Cabal library

I see. I had done

sudo cabal install HAppS-Server

but this just installed with root ownership in my home directory.

I'm now trying with

sudo cabal install --global HAppS-Server

I think you need to install HAppS-Data etc globally... I'm not sure why locally installed (ie, only your user) packages wouldn't be picked up by runghc Setup.hs'ing, but if they are install system wide it should definitely work.

I think it is cabal --global install foo

After a little drama with zlib, I managed to get cabal-install installed.

I then attempted to do

cabal install HAppS-Server

since this is a module with a lot of dependencies, and in rapid development flux, so perenially painful for me to install.

The result is that I managed to install everything up to HAppS-State, which I think is the last dependency, but then seemed to hang indefinitely in the middle of installing HAppS-Server at the end.

OK, I thought, then perhaps I can do normal runghc Setup.hs after downloading and unzipping the tar from

http://hackage.haskell.org/cgi-bin/hackage-scripts/package/HAppS-Server-0.9....

However, this resulted in error

thartman@thartman-laptop:~/haskellInstalls/smallInstalls/HAppS-Server-0.9.2.1>runghc Setup.hs configure ... Setup.hs: At least the following dependencies are missing: HAppS-Data >=0.9.2...

Strange, because I had just installed that module via cabal-install, and I could load it in ghci with :m +HappS.Data.

I then ran ghc-pkg and got this strange result that my packages were broken into two different files. Is this by design?

ghc-pkg list /usr/local/lib/ghc-6.8.2/package.conf: Cabal-1.2.3.0, Cabal-1.3.11, Cabal-1.5.2, DeepArrow-0.2, .... /home/thartman/.ghc/i386-linux-6.8.2/package.conf: HAppS-Data-0.9.2.1, HAppS-IxSet-0.9.2.1, HAppS-State-0.9.2.1,

I am curious if anybody else is able to install HAppS-Server using cabal install, and whether they can shed any light on the other isuses I raised.
