I am sorry to trouble you but I have problems to install Haskell.
Things run smoothly when I do the command ‘./configure’, But some errors
appeared when I
run the command ‘make’. The details are as follows(in red font):
Distribution/Client/HttpUtils.hs:127:49:
Couldn't match expected type `network-2.2.1.2:Network.URI.URI'
against inferred type `URI'
In the fourth argument of `AuthBasic', namely `uri'
In the first argument of `Just', namely
`(AuthBasic "" usr pwd uri)'
In the expression: Just (AuthBasic "" usr pwd uri)
Distribution/Client/HttpUtils.hs:135:37:
Couldn't match expected type `network-2.2.1.2:Network.URI.URI'
against inferred type `URI'
In the `rqURI' field of a record
In the expression:
Request
{rqURI = uri, rqMethod = GET,
rqHeaders = [Header HdrUserAgent userAgent],
rqBody = ByteString.empty}
In the definition of `mkRequest':
mkRequest uri
= Request
{rqURI = uri, rqMethod = GET,
rqHeaders = [Header HdrUserAgent userAgent],
rqBody = ByteString.empty}
where
userAgent = "cabal-install/" ++ display
Paths_cabal_install.version
Error:
Building the cabal-install-0.6.2 package failed
make: *** [build.stamp] Error 2
If I install cabal-install manually, the errors will be:
# /usr/bin/runhaskell Setup configure
Configuring cabal-install-0.6.2...
Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.
package HTTP-4000.0.6 requires network-2.2.1.2
