Unfortunately cabal-dev ghci does not work in this project, i get an error:
Loading package download-0.3.2 ... linking ...
ghc: /home/stulli/haskell/ifdl/cabal-dev//lib/download-0.3.2/ghc-7.4.1/HSdownload-0.3.2.o: unknown symbol `stat64'
ghc: unable to load package `download-0.3.2'
So i try runhaskell, but it uses the packages that come installed with cabal instead of cabal-dev and thus fails.
update: runhaskell produces the same error:
$ runhaskell -isrc:src/test -package-conf=cabal-dev/packages-7.4.1.conf src/test/Test.hs
Test.hs: /home/stulli/haskell/ifdl/cabal-dev//lib/download-0.3.2/ghc-7.4.1/HSdownload-0.3.2.o: unknown symbol `stat64'
Test.hs: Test.hs: unable to load package `download-0.3.2'
cabal-dev install on the other hand works without problems.
回答1:
You can try something like the next:
runhaskell -package-conf=cabal-dev/packages-7.0.3.conf main.hs
But I think if cabal-dev ghci
doesn't work, then runhaskell
will not work too. You need to find out what is wrong with download
package.
回答2:
To use runhaskell
with cabal sandboxes (cabal >= 1.18), run the command
runhaskell -package-db=.cabal-sandbox/i386-windows-ghc-7.6.3-packages.conf.d <file.hs>
substituting the proper *-packages.conf.d
directory for your GHC version.

The cabal-dev
setup doesn't work very well for ghci
, so it might very well be that it also doesn't work well for runhaskell
. Maybe virthualenv will work better for this use case?
