[Hackage] #812: setup.exe: internal error: unexpected package db stack: [UserPackageDB]
#812: setup.exe: internal error: unexpected package db stack: [UserPackageDB] ---------------------------------+------------------------------------------ Reporter: fryguybob | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.10.0.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: Windows | ---------------------------------+------------------------------------------ When trying to install Cairo with the new Haskell Platform (2011.2.0.0). I get the error: {{{
cabal install cairo --ghc-option=-DCABAL_VERSION_MINOR=10 ... Registering cairo-0.12.0... setup.exe: internal error: unexpected package db stack: [UserPackageDB] ... }}}
The CABAL_VERSION_MINOR flag is suggested if you try without it but doesn't make a difference in the outcome. I'm on Windows 7 64-bit. {{{
cabal --version cabal-install version 0.10.2 using version 1.10.1.0 of the Cabal library ghc --version The Glorious Glasgow Haskell Compilation System, version 7.0.2 }}}
Attached is the -v2 log. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/812 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
#812: setup.exe: internal error: unexpected package db stack: [UserPackageDB] ---------------------------------+------------------------------------------ Reporter: fryguybob | Owner: Type: defect | Status: closed Priority: normal | Milestone: Component: cabal-install tool | Version: 1.10.0.0 Severity: normal | Resolution: invalid Keywords: | Difficulty: unknown Ghcversion: | Platform: Windows ---------------------------------+------------------------------------------ Changes (by fryguybob): * status: new => closed * resolution: => invalid Comment: If I change Gtk2hsSetup.hs from: {{{ #!hs #if CABAL_VERSION_CHECK(1,10,0) installedPkgInfo pkg lbi inplace [packageDb] #else installedPkgInfo pkg lbi inplace packageDb #endif }}} to {{{ #!hs #if CABAL_VERSION_CHECK(1,10,0) installedPkgInfo pkg lbi inplace (withPackageDB lbi) #else installedPkgInfo pkg lbi inplace packageDb #endif }}} It registers correctly. The packageDb here is defined as: {{{ #!hs packageDb = case flagToMaybe (regPackageDB regFlags) of Just db -> db Nothing -> registrationPackageDB (withPackageDB lbi) }}} In Distribution\Simple\Register.hs it has: {{{ #!hs -- FIXME: there's really no guarantee this will work. -- registering into a totally different db stack can -- fail if dependencies cannot be satisfied. packageDbs = nub $ withPackageDB lbi ++ maybeToList (flagToMaybe (regPackageDB regFlags)) }}} Anyway, it appears that the issue is with Gtk2HsSetup.hs and I will close this and add to a related ticket there (http://hackage.haskell.org/trac/gtk2hs/ticket/1203). -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/812#comment:1 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
