patch applied (cabal): Don't propagate cc-options to the InstalledPackageInfo
by Simon Marlow 21 Aug '08

21 Aug '08

Thu Aug 21 06:25:51 PDT 2008 Simon Marlow <marlowsd(a)gmail.com> * Don't propagate cc-options to the InstalledPackageInfo cc-options is for options to be passed to C compilations in the current package. If we propagate those options to the InstalledPackageInfo, they get passed to C compilations in any package that depends on this one, which could be disastrous. I've seen cc-options like these: cc-options: -optc-std=c99 cc-options: -D_FILE_OFFSET_BITS=64 Cc-options: -Wall these are all clearly intended to be local, but are in fact currently propagated to all dependent packages.

[Hackage] #334: GHC_PACKAGE_PATH with trailing colon disrespected

[Hackage] #326: Cabal should support Cabal-version-dependent Setup.hs
by Hackage 20 Aug '08

#326: Cabal should support Cabal-version-dependent Setup.hs ----------------------------+----------------------------------------------- Reporter: claus | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------+----------------------------------------------- The manual says about non-standard `Setup.hs`: "good luck". But there are packages that need non-standard `Setup.hs`, often just very small ones. And all of them risk breakage when Cabal changes. The first issue is to specify the dependency on a particular Cabal version (#284). The next issue is that package authors often know how to write their `Setup.hs` for different versions of Cabal, but have to pick one or the other. It would be better to have `Setup.hs` code adapt to as many Cabal versions as possible. Since version mismatch leads to compile errors, that seems to imply either - separate sources (`Setup-v1.4.hs`, `Setup-v1.5.hs`, etc.) - one source, with CPP (#if Cabal==1.4 ..) If I read [http://www.haskell.org/pipermail/cabal- devel/2008-August/003576.html Add auto-generated CPP macros for package version testing] correctly, that almost provides package version info via CPP. It would only need to provide precise versions instead of lower bounds, and for the Cabal package. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/326> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #329: Cabal regenerates Paths_package unnecessarily

#329: Cabal regenerates Paths_package unnecessarily ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.4.0.1 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------+----------------------------------------------- Every time I run {{{cabal install}}}, cabal rebuilds and relinks part of my application, because it generates a fresh Paths_package, even though it is the same. When overwriting Paths_package Cabal should first check to see if the code changes, and if not, not write anything. Example of the bug: {{{ C:\Neil\hoogle>cabal --version cabal-install version 0.5.2 using version 1.4.0.1 of the Cabal library C:\Neil\hoogle>cabal install Resolving dependencies...

cabal-install calls setup with unrecognised distpref flag
by José Pedro Magalhães 19 Aug '08

19 Aug '08

Hello all, Recently, while developing a package here in the group, we changed the build-type from "Simple" to "Custom" to allow for "cabal test". The Setup.hs simply calls defaultMainWithHooks with simpleUserHooks where runTests has been redefined. The problem is that this change gives me the following error when invoking "cabal build" (after invoking "cabal configure"): setup.exe: Unrecognised flags: --distpref=dist runhaskell Setup.hs build works fine, though. This happens on a win64 machine, cabal-install version 0.5.1 using version 1.4.0.1 of the library. On a mac there seem to be no problems, though. Am I doing something wrong? Thanks, Pedro
