I am trying to install helm. When I try to install it, however I get this error:
$ cabal install helm
Resolving dependencies...
Configuring sdl2-1.1.0...
cabal: The pkg-config package 'sdl2' version >=2.0.3 is required but it could
not be found.
Failed to install sdl2-1.1.0
cabal: Error: some packages failed to install:
helm-0.6.1 depends on sdl2-1.1.0 which failed to install.
sdl2-1.1.0 failed during the configure step. The exception was:
ExitFailure 1
When I go to install sdl2 by itself, I get a similar message.
$ cabal install sdl2
Resolving dependencies...
Configuring sdl2-1.1.0...
cabal: The pkg-config package 'sdl2' version >=2.0.3 is required but it could

I don't understand. According to Hackage, sdl2 is at version 1.1, but installing it requires version 2.0.3? I've tried this in and out of a sandbox. Results of ghc-pkg list are here if you think they're relevant: http://pastebin.com/tFrsfPFe
I'm on Ubuntu btw.
Help?
Another thing which could happen (happened to me) for other installs is that the PKG_CONFIG_PATH variable might not point to the package config file (sdl2.pc, for me in the /usr/local/lib/pkgconfig directory). pkg-config uses some default directories ('/usr/lib/pkgconfig' and '/usr/share/pkgconfig'), but if the sdl.pc file isn't in one of these, you'll have to specify the directory in the environment variable. You can check this with echo $PKG_CONFIG_PATH
If it turns out you need to set the variable, just use export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig (or to whatever directory your sdl2.pc file lives in)
I ran into the same problem, and I just want to add my solution here for the record. The native sdl2 libraries need to be installed first by following the directions here: https://github.com/haskell-game/sdl2#building

Im trying to install hsparql, cabal version 1.22.1.1
cabal install hsparql
gives
Could not find module `Network.URI'
It is a member of the hidden package `network-uri-2.6.0.1'.
Perhaps you need to add `network-uri' to the build-depends in your .cabal file.
Use -v to see a list of the files searched for.
Failed to install hsparql-0.2.5
cabal: Error: some packages failed to install:

but
cabal install network-uri
shows
All the requested packages are already installed:
network-uri-2.6.0.1
what could be the problem?

I'm new with Haskell, and I'm now sure if having two repositories could be a problem. My work platform is Ubuntu 14.04, GHC 7.6.3, and cabal 1.20.
I am having lots of problems with cabal-install:
1: Every time I do cabal update, it tells me to do cabal install cabal-install, so I do, and then when I do cabal update again, it says the same thing.
2: When I try to install ghc-mod from hackage, it gives me this error:
[username#arch ~]$ cabal install ghc-mod
In order, the following will be installed:
haskell-src-exts-1.14.0 (reinstall) changes: pretty-1.1.1.1 -> 1.1.1.0
hlint-1.8.55 (reinstall)
ghc-mod-3.1.4
setup: The program happy version >=1.17 is required but it could not be found.
ghc-mod-3.1.4 depends on haskell-src-exts-1.14.0 which failed to install.
haskell-src-exts-1.14.0 failed during the configure step.
hlint-1.8.55 depends on haskell-src-exts-1.14.0 which failed to install.
So the problem was The program happy version >=1.17 is required but it could not be found., so I installed happy 1.19.2 using cabal install happy without problems.
I tried cabal install ghc-mod again, same error, so I tried cabal install haskell-src-exts --reinstall --force-reinstalls. It gave me the following error:
[username#arch ~]$ cabal install haskell-src-exts --reinstall --force-reinstalls
Configuring haskell-src-exts-1.14.0...
setup: The program happy version >=1.17 is required but it could not be found.

cabal: Error: some packages failed to install:

Basically The program happy version >=1.17 is required but it could not be found.. So happy is the problem again?
I have also tried downloading the tar.gz files from hackage and using cabal install on the
.cabal file, also modified the .cabal file to ignore dependencies, still failed.
cabal install places executables in ~/.cabal/bin.
If you add it to your path, you will be able to use the new executables installed by cabal:
$ PATH=$HOME/.cabal/bin:$PATH
I encountered with same problem and I solved the problem with installing happy package(confusing package name). So install it with your package manager(apt-get, pacman etc) before install package with cabal. This should be fix the problem.
I'm trying to install the Idris language in an OSX Lion using the installation guide provided on the official tutorial. I have alraedy installed GMP. This is the error I get:

I was having this same problem on OSX Mavericks. To get Idris to compile, I used homebrew to install gmp, then I had to do 'export PKG_CONFIG_PATH=/usr/local/Cellar/libffi/3.0.13/lib/pkgconfig', and then 'cabal install idris -f-LLVM'. I got the tip to export the PKG_CONFIG_PATH variable from this site:
https://groups.google.com/d/msg/idris-lang/gxcdvRIA2OI/NqKSd4zHkI4J
Mavericks already had libffi installed, and I didn't want to install a second copy from source, which is what the PKG_CONFIG_PATH trick helped me avoid. Do 'brew info libffi' to find the correct path to export. Hopefully someone will create a homebrew formula for Idris soon...
The first error indicates you should install the LLVM development packages of your distribution (not through cabal) and the second indicates you should install the development package for the GCC libffi library. What Linux distribution are you using? Or are you on Windows/Mac?
I install wxWidgets with macports then ran the command: sudo cabal install wx which output included:

Configuring wxcore-0.12.1.6...
setup: Missing dependency on a foreign library:
* Missing C library: wx_macu-2.8
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
cabal: Error: some packages failed to install:
wx-0.12.1.6 depends on wxcore-0.12.1.6 which failed to install.
wxcore-0.12.1.6 failed during the configure step. The exception was:
ExitFailure 1
I got the same error when I used this command: sudo cabal install wx --extra-include-dirs=/opt/local --extra-lib-dirs=/opt/local. How can I install wx_macu-2.8, or do what I need to do to fix this problem?
This is saying that you are missing a C library, not a Haskell library. Cabal can't install arbitrary C libraries.
Check the package manager for your distribution to make sure you have everything to do with wxWidgets-2.8, including any developer packages.
