I'm trying to work on Haskell in IntelliJ IDEA on Windows 8.
I installed the latest Haskell plugin, and found that it requires ghc.exe, cabal.exe and ghc-mod.exe prepared. Haskell Platform (x64) originally contains ghc.exe and cabal.exe, so what I need in order to make the plugin work is ghc-mod.exe.
Just as many guides say, I tried installing it through cabal like this:
cabal install ghc-mod
It failed installing haskell-src-exts in the middle of the process, so I installed happy and tried the same command again. Then it succeeded to install src-exts, yet not ghc-mod. Cabal produced this error log:
Building ghc-mod-0.3.0...

Perhaps you meant `ExplicitForAll' (imported from Language.Haskell.Exts.Extension)
This doesn't make sense to me at all. What can I do?

I suspect this is either a problem with ghc or cabal-install:

As you can see, cabal-install or ghc, whichever is causing the problem, seems to be inducing undesirable laconism now. According to my cabal config, I am running at a default verbosity level of 1. Is there some configuration option that could have caused this particular behavior? In other words, how can I restore the original behavior? Version 1.18.0.2
Thanks to #Michael Snoyman for pointing out that configuring a jobs parameter or explicitly passing it as a -j flag will redirect much of the information that pertains to build output to a text file. More information is available here.
I'm trying to install c2hs with cabal install c2hs.
I created ~/.cabal/bin to install the binary beforehand.
With the command cabal install c2hs to get the errors.

cabal: Error: some packages failed to install:
c2hs-0.16.5 failed during the building phase. The exception was:
ExitFailure 1
What is wrong with the installation? The ghc version is 7.6.3.
The install worked for me right now, on my Ubuntu box, so I can say for sure that c2hs isn't broken for everyone right now.
I think you might have version issues.... Try
cabal update
and try the install again.
In particular-
The function Prelude.catch was moved to Control.Exception.catch recently, see https://ghc.haskell.org/trac/ghc/ticket/4865. I downloaded the c2hs sources (using cabal unpack c2hs), and looked at what headers Paths_c2hs.hs needs (this seems to be the file with the import problems). This is what the imports section contained-
import qualified Control.Exception as Exception
import Data.Version (Version(..))
import System.Environment (getEnv)
import Prelude
(Paths_c2hs.hs is autogenerated, so I had to build it first).
Indeed, it was using Control.Exception. Because this is a module in base, you should have it, and probably just have out of date/mismatched packages. (In fact, my file's line numbers don't match your error message line numbers above- This is another indication we are using different versions, and I believe mine is up to date :) .)
Although I think that the "cabal update" will fix the problem, if not, try looking in these two places-
Does Control.Exception.catch exist in your base modules? Just try to compile an empty program with an dummy reference to catch, like this-
import Control.Exception
x = catch
main = undefined
Does your autogenerated Paths_c2hs.hs point to the correct catch function. Just use cabal to unpack, configure and build c2hs and then look at dist/build/autogen/Paths_c2hs.hs. (you will probably hit your error in the build phase, but given what you have shown above, it will happen after the Paths_c2hs.hs creation).
The issue was that I installed two different versions of ghc on my mac: one from brew install ghc and the other from haskell platform.
I had to install the newest version of haskell platform, but before doing that I also needed to uninstall old version uninstall-hs only VERSION and brew unistall ghc.
After reinstalling the newest haskell platform, the compilation works fine.

How to install Haskell cabal tool for Haskell 7.6.1 on Mac OSX?
Other method can be using brew brew install haskell-platform.
is there a GUI package that is still up-to-date?
I tried installing both wxHaskell and gtk2hs today and both fail on dependencies I just cannot solve (wxHaskell cannot find some wxWidget libs and while trying the glade tutorial gtk2hs fails on a missing pkg-config libglade2-0 I installed too).
I guess it's just some problem with me not understanding the linux/cabal/package install things good enough but is there a up-to-date tutorial how to get started (install) some GUI lib for Haskell somewhere around?
Here are the errors:

This is really frustrating me - maybe someone can help me here - thank you!

Are you sure you have libglade2-dev installed ? That should fix it.
Coming from ArchLinux i had the same problem at first when i didn't know there were separate dev libraries, i don't remember having to do this in arch.

This problem occurs on both my Mac and in my Fedora VM. Does anybody know how to fix this? Thanks!
You need to add the path in which the Gtk2Hs build tools are stored to your $PATH environment variable, so that the build process can find them. On Linux, it's $HOME/.cabal/bin. On OS X, it's $HOME/Library/Haskell/bin (although that might just be if you're using the Haskell Platform — if that doesn't work, try $HOME/.cabal/bin).
To add a directory to your $PATH, run export PATH=directory:$PATH. You should probably add this to your shell's startup file (it depends on your shell and OS — probably either ~/.bashrc, ~/.profile or ~/.bash_profile). (You'll need to do so if you want to run any programs you install with cabal directly, anyway.)

These aren't cabal errors. The vector package doesn't build out of the box with GHC 7 (yet). You're an early adopter, jumping on GHC 7 before the Haskell Platform version is released.
As an early adopter, your duty is to report build errors to package maintainers.
