问题 I am using HaskellPlatform-2012.4.0.0 on Win7. It's installed as portable. Paths are managed through .bat file so ghci and ghc works. But cabal installs it self at C:\Users\name\AppData\Roaming\cabal\ To circumvent that I did: cabal update edit config file delete all files except config Changed paths: remote-repo-cache: d:\h1\cabal\packages world-file: d:\h1\cabal\world build-summary: d:\h1\cabal\logs\build.log It works, but it's far from truly portable. Cabal config is bigger problem. It

问题 The command cabal haddock has very useful --hyperlink-source option. I would like to have the source hyperlinked when building documentation with cabal install . The ticket #517 seems to be just about it: http://hackage.haskell.org/trac/hackage/ticket/517 However, perhaps it is possible to set this flag via ~/.cabal/config file? If not, how can I get working cabal-install build with the patch from #517 without installing Cabal-1.9, which is currently mandatory (due to one patch from December)

问题 How do I tell stack to build my executable and all its dependencies with -prof ? Simply adding it to ghc-options in the .cabal file is not enough, because it only tries to build the executable with profiling enabled, which fails. 回答1: Profiling builds with Stack 1.0.0 and newer To build with profiling enabled: stack build --profile You may need to run stack clean first , but this should be fixed in Stack 1.5.0. To profile: stack exec --profile -- <your program> +RTS <profiling options> where

问题 using cabal; came accross this error. did cabal install and this happened . failed during the building phase. The exception was: ExitFailure 1 checked my log; it said : dist/package.conf.inplace: inappropriate type I have 0 ideas what's going on. cabal build works though . #STRANGE CURRENTLY: CABAL version: 1.22.0.0. Glorious Glasgow Haskell Compilation version: 7.8.4 回答1: Possible explanation: you have upgraded GHC to 7.10, which does things a bit differently I gather, but not upgraded cabal

问题 I'm installing Haskell on Windows based on the instructions at https://www.haskell.org/platform/ and looking at step 3, it says, Modify your cabal config file (you can verify the location by running "cabal user-config init") to contain the following lines: extra-prog-path: C:\Program Files\Haskell Platform\8.0.2\msys\usr\bin extra-lib-dirs: C:\Program Files\Haskell Platform\8.0.2\mingw\lib extra-include-dirs: C:\Program Files\Haskell Platform\8.0.2\mingw\include But the auto generated config

问题 I have a Haskell project that aims to create some C++ bindings. I've written the C wrappers and compiled them into a stand-alone statically linked library. I'd like to write the Haskell bindings to link statically to the C wrappers so that I don't have to distribute the C wrappers separately but I can't seem to get it working and would appreciate some help. I specify the C library as an extra library but my cabal build step doesn't seem to add it to compile command. I've created a small

问题 I am trying to build a simple program in Haskell using stack. I created a new project using stack new and did a stack setup after that. The template builds fine. I want to experiment with binary file parsing, so I imported Data.ByteString . My build-depends in the cabal file look like this: build-depends: base >= 4.7 && < 5 , bytestring >= 0.10.6 , binary >= 0.7.5 stack ghci now just works, but stack build is still not happy. Can someone tell me what I did wrong here? Here is the complete

问题 I have a fairly simple haskell project set up, where I just want to have the framework working with testing and so on before I actually start coding. I have my source files for an executable in a /src directory (where / is the project's root) and my tests in a /testsuite directory. /testsuite contains a simple test file called TestSuite.hs with main = Test.Framework.defautMain tests as the implementation of main. The problem is, when I run cabal clean && cabal configure --enable-tests &&
