[Hackage] #177: Include-dirs, extra-lib-dirs with spaces doesn't work under Windows

#177: Include-dirs, extra-lib-dirs with spaces doesn't work under Windows ----------------------+----------------------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal | Version: 1.2.2.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.6 Platform: Windows | ----------------------+----------------------------------------------------- Trying to build the HDBC-PostGreSQL database driver[1] revealed some poor handling of pathames under Windows. The package requires that the paths to postgre header and libraries files be added to the .cabal file. My initial attempt was the obvious: {{{ include-dirs: C:\Program Files\PostgreSQL\8.2\include, C:\Program Files\PostgreSQL\8.2\include\server, . extra-lib-dirs: C:\Program Files\PostgreSQL\8.2\include, C:\Program Files\PostgreSQL\8.2\include\server }}} However, the package would not build. The include files "pg_config.h" and some others were not found. Using single or double quotes did not help. Finally, I moved the installation to "C:\pgsql" and updated the .cabal file: {{{ include-dirs: C:\pgsql\include, C:\pgsql\include\server, . extra-lib-dirs: C:\pgsql\lib }}} And the package built. It seems the spaces in the first path caused the problem. For reference, this it the configure output on my machine: {{{ Configuring HDBC-postgresql-1.0.1.0... configure: Dependency base-any: using base-2.1.1 configure: Dependency mtl-any: using mtl-1.0.1 configure: Dependency HDBC>=1.0.0: using HDBC-1.0.1 configure: Dependency parsec-any: using parsec-2.0 configure: Using install prefix: C:\Program Files configure: Binaries installed in: C:\Program Files\Haskell\bin configure: Libraries installed in: C:\Program Files\Haskell\HDBC- postgresql-1.0.1.0\ghc-6.6.1 configure: Private binaries installed in: C:\Program Files\HDBC- postgresql-1.0.1.0 configure: Data files installed in: C:\Program Files\Common Files\HDBC- postgresql-1.0.1.0 configure: Using compiler: c:\ghc\ghc-6.6.1\bin\ghc.exe configure: Compiler flavor: GHC configure: Compiler version: 6.6.1 configure: Using package tool: c:\ghc\ghc-6.6.1\bin\ghc-pkg.exe configure: Using ar found on system at: c:\ghc\ghc-6.6.1\bin\ar.exe configure: Using haddock found on system at: C:\haddock\haddock-0.8\haddock.exe configure: No pfesetup found configure: Using ranlib found on system at: c:\MinGW\bin\ranlib.exe configure: Using runghc found on system at: c:\ghc\ghc-6.6.1\bin\runghc.exe configure: Using runhugs found on system at: C:\Program Files\WinHugs\runhugs.exe configure: No happy found configure: No alex found configure: Using hsc2hs: c:\ghc\ghc-6.6.1\bin\hsc2hs.exe configure: No c2hs found configure: No cpphs found configure: No greencard found }}} Feel free to email me at jgbailey AT gmail DOT com for more info.

#179: support GHC's main-is extension --------------------------+------------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal | Version: 1.2.2.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.4.2 Platform: Linux | --------------------------+------------------------------------------------- Query on haskell-cafe: http://haskell.org/pipermail/haskell- cafe/2007-November/034686.html {{{ It seems the meaning of the -main-is switch for GHC and the Main-Is build option for Cabal executables differ. With GHC, I can point to any function "main" in any module, but in Cabal I must point to a filename with precisely the module name "Main". This is tying my hands with regard to organizing a default executable and exposing some of its functionality as a library. Is there a way to get around this restriction? Concretely, I want to point Cabal's Main-Is to Program/Main.hs which starts with module Program.Main where instead of just module Main where }}} So in GHC it has this meaning: http://haskell.org/ghc/docs/latest/html/users_guide/options-phases.html #options-linker {{{ -main-is thing The normal rule in Haskell is that your program must supply a main function in module Main. When testing, it is often convenient to change which function is the "main" one, and the -main-is flag allows you to do so. The thing can be one of: A lower-case identifier foo. GHC assumes that the main function is Main.foo. An module name A. GHC assumes that the main function is A.main. An qualified name A.foo. GHC assumes that the main function is A.foo. }}} In Cabal the {{{main-is:}}} field specifies the '''file name''' of the Main module. GHC's {{{-main-is}}} flag is an extension to Haskell that is not supported by the other Haskell implementations. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/179> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#365: new cabal-install ignores prefix settings in my config file, fails every install ---------------------------------+------------------------------------------ Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.3 Platform: Linux | ---------------------------------+------------------------------------------ Installing xhtml-3000.2.0.1 with cabal fails because it tries to write to /usr/local, to which it doesn't have access. This shouldn't happen because my whole ghc installation lives in ~/usr and cabal is configured to put stuff there. A manual build (using ./Setup configure --prefix=... + build + install) works. Oops. I just noticed that installing ''any'' package with cabal fails. It's just that xhtml is the first out-of-date package on my system. The last thing I did before was 'cabal upgrade cabal-install', which installed a new Cabal and cabal-install. Now every package (with verbose=2) says stuff like {{{ Using Cabal-1.4.0.2 compiled by ghc-6.8 Using compiler: ghc-6.8.3 Using install prefix: /usr/local Binaries installed in: /usr/local/bin Libraries installed in: /usr/local/lib/cabal-install-0.5.2/ghc-6.8.3 Private binaries installed in: /usr/local/libexec Data files installed in: /usr/local/share/cabal-install-0.5.2 Documentation installed in: /usr/local/share/doc/cabal-install-0.5.2 }}} So it seems like the new cabal ignores my ~/.cabal/config file since specifying a --prefix on the command line works fine.
