[Hackage] #536: c2hs needs to be given include dirs of dependent packages

#536: c2hs needs to be given include dirs of dependent packages ------------------------------+--------------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Cabal-1.8 Component: Cabal library | Version: 1.6.0.2 Severity: normal | Keywords: Difficulty: easy (<4 hours) | Ghcversion: Platform: | ------------------------------+--------------------------------------------- Currently for c2hs we pass include dirs of the package itself. However for hsc2hs we also pass the include dirs of dependent packages. This is important because packages like base, rts etc have some special include dirs that we need. Especially on Windows where the mingw header files are in a special location that's recorded in the package info for base or rts. This is needed for portably binding to things in the mingw Windows header files, but also for generic posix things that happen to be defined in the mingw header files. It should not be too hard. Much of the code can be shared with the existing code for hsc2hs. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/536> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #537: c2hs needs to be told where gcc -E lives on Windows

#537: c2hs needs to be told where gcc -E lives on Windows ------------------------------+--------------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Cabal-1.8 Component: Cabal library | Version: 1.6.0.2 Severity: normal | Keywords: Difficulty: easy (<4 hours) | Ghcversion: Platform: Windows | ------------------------------+--------------------------------------------- c2hs uses cpp or gcc -E to pre-process header files. On Windows this is not typically on the %PATH%. Cabal already knows how to find ghc's instance of gcc and how it must be called. This is already used for telling hsc2hs to use the right gcc. It should be fairly easy to do the same thing for c2hs and to share the code between the two. See also #536. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/537> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

I set LD_LIBRARY_PATH to point to /sw/lib to point to the location of gmp (fink). This fixed my ghc compilation problem, but the bootstrap script still fails. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/535> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #534: cabal haddock should --hyperlink-source by default

#534: cabal haddock should --hyperlink-source by default ----------------------------------+----------------------------------------- Reporter: adamvo | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.6.0.1 Severity: normal | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: Platform: | ----------------------------------+----------------------------------------- The results from cabal haddock --hyperlink-source are very nice, but quite frequently the haddocks are not built with this (all recent hackage libs iirc). Would there be a problem with generating the source links by default if and only if a HsColour can be found? Or should this issue instead be resolved at the haddock level? -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/534> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
