[Hackage] #899: package documentation not built

#899: package documentation not built --------------------------------+------------------------------------------- Reporter: mndrix | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: hackageDB website | Version: 1.10.1.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | --------------------------------+------------------------------------------- I uploaded a package three days ago (network-bitcoin) and it still appears not to have been built. I see no logs directory at http://hackage.haskell.org/packages/archive/network-bitcoin/0.1.0/ and no documentation at http://hackage.haskell.org/package/network-bitcoin-0.1.0 It looks like most other new packages are behaving similarly. I searched for existing bugs or a policy statement describing the expected time between upload and build, but found nothing. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/899> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

How to build relocatable packages with cabal
by Tim Cuthbertson 14 Nov '11

14 Nov '11

I'm trying to distribute cabal-built haskell libraries using zero-install ( http://0install.net/ ). The main requirement of 0install packages is that they - be relocatable to arbitrary paths without modifying them (packages are read-only and contents are verified by a manifest, so prefix-dependant binaries are impossible) - be runnable without modification as long as environment variables are correctly set up so that they can find their dependencies. I believe $GHC_PACKAGE_PATH should be sufficient for most cabal packages from this very old ticket ( http://hackage.haskell.org/trac/hackage/ticket/469 ), I see: > Configuring a relocatable package should be something that is done explicitly. At the moment it is done simply by configuring it in the right way, but Cabal is never aware that the user is trying to construct a relocatable package. Are there any instructions on how to configure cabal to build a relocatable package? I have tried setting prefix to an empty string and "/" in the configure step, but neither of those work. My current build process is: ---- #!/bin/sh set -eux cd "$SRCDIR" cabal configure -v --builddir="$BUILDDIR" --prefix="/" cabal build -v --builddir="$BUILDDIR" cabal copy --builddir="$BUILDDIR" --destdir="$DISTDIR" cabal register --gen-pkg-config="$DISTDIR/package.conf" --builddir="$BUILDDIR" ---- But the created package doesn't seem valid (`ghc-pkg list` can't even parse it, and I'm not sure what the chances of it actually working would be). I'm specifically trying to build hspec here, but ideally there would be some recipe that works for all typical cabal projects. Any assistance wooud be appreciated. Thanks, - Tim.

I have a small application that I'd like to redistribute in binary form, but it needs data files, and I've no idea how I'd create a relocatable package on Linux, OS X, or Windows at the moment. At least on OS X and Linux, I can fudge by just installing it in /usr, but I don't have any such luxury on Windows. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/469#comment:2> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

There is a charset in the XML declaration `<?xml version="1.0" encoding="UTF-8"?>`, but that is ignored by Firefox because of the non-XML `Content-Type`. Therefore, the wrong encoding is detected and the Unicode symbols get mangled. Possible fixes include sending `Content-Type: text/html; charset=UTF-8`, or sending `Content-Type: application/xhtml+xml` so that the XML declaration is respected , or both (`Content-Type: application/xhtml+xml; charset=utf-8`), or adding equivalent `<meta http-equiv="Content-Type">` tags. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/767> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
