#238: haddock2 is not passed -D__HADDOCK__ or cpp-options ----------------------------------+----------------------------------------- Reporter: ross(a)soi.city.ac.uk | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------------+----------------------------------------- With haddock-1, Cabal invokes cpp, passing it ARCH and OS defines, -D__HADDOCK__ and the contents of cpp-options. However haddock-2 invokes cpp itself via the GHC API, which passes this cpp the ARCH and OS defines, but it doesn't get the others. It might also be a good idea to give __HADDOCK__ a numeric value, because GHC extensions need not be hidden from the new one. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/238> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #189: Handle framework paths (-F) in Cabal

#189: Handle framework paths (-F) in Cabal --------------------------+------------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal | Version: 1.2.2.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.1 Platform: Mac OS | --------------------------+------------------------------------------------- There's been some discussion on the GHC trac ([http://hackage.haskell.org/trac/ghc/ticket/1931 1931], [http://hackage.haskell.org/trac/ghc/ticket/1798 1798], [http://hackage.haskell.org/trac/ghc/ticket/1395 1395]) about adding framework search paths (gcc's `-F` flag, and ghc's `-framework-path` flag). Currently Cabal handles `-framework`, but not `-framework-path`. I propose the following behavior for Cabal: 1. Add a `framework-path:` field which will pass `-framework-path` to `ghc` and `-F` to `gcc`, `hsc2hs`, et. al. 2. Always add `-F$HOME/Library/Frameworks` as an argument to the above programs (regardless of any `framework-path` entries). I believe `#1` to be uncontroversial. My reasoning for `#2` is the following: - `$HOME/Library/Frameworks` is the standard location to put frameworks if you do not have administrative access. - Without it, `readline.cabal` (e.g.) would need {{{ framework-path: /Users/judah/Library/Frameworks }}} which is not portable between machines. Finally, note that these flags only affect build behavior, not runtime loading of libraries (which searches `$HOME/Library/Frameworks` by default). See [http://hackage.haskell.org/trac/ghc/wiki/OSXFrameworks OSXFrameworks] for more info. -Judah -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/189> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

Thu Feb 19 16:37:38 CET 2009 Andrea Vezzosi <sanzhiyan(a)gmail.com> * rewrite of Distribution.Simple.Haddock In addition to (hopefully) making clear what's going on we now do the additional preprocessing for all the versions of haddock (but not for hscolour) and we run cpp before moving the files.

[Hackage] #512: Use a proper exception for the 'die' utility function

#512: Use a proper exception for the 'die' utility function ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.6.0.1 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- Currently the `die` function prints the error message to stderror and throws an exit with exception. This is not a good approach for library code. Instead it should throw an user error exception with the string message. A top level handler in `Distribution.Simple.main` or `cabal- install` should catch this, print it as before and throw an exit exception. See also #510 for an example of how this causes problems. The `readPackageDescription` ends up throwing the exit exception when it would be more helpful to clients for it to throw an ordinary exception containing the error message. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/512> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

Cabal install broken with GHC 6.10.1.* HEAD
by Neil Mitchell 02 Mar '09

02 Mar '09

Hi, I've just installed GHC 6.10.1.20090225 which has set base as 3.0.3.0, instead of the 3.0.2.0 which GHC 6.10.1 had (I think). This causes cabal install to break, as it implicitly adds base == 3.0.2.0 which nothing has so nothing installs. Could a new version of cabal install be released that fixes this? I'm totally hooked on cabal install and now having upgraded GHC I've lost it. The likely result is that I'll have to downgrade my GHC because cabal is just too useful! Thanks Neil
