I think the reason it took longer to build HAppS-Server is that
previously, when I was installing the MyProject example from happs.org
I was using searchpath.
I guess searchpath doesn't compile every single haskell module,
whereas runghc Setup build and cabal install does.

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.
'cabal install' installs packages to your user database by default. However, 'Setup configure' only uses packages from the global database unless the --user flag is passed.
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,
Yep, this is by design. The first is a global database that will require root access to modify. The second is your user database which you can modify without root access.
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.
Thomas.
I tried building HAppS-server the other day, and had a similar experience. It seems that HAppS uses some incredibly elaborate TH/typeclass hacks that take gobs of resources to compile -- my box actually ran out of memory attempting to build it.
