I want to try unicode with haskell, and the Data.Text docs say I need text-icu. This is what I tried:
Mac OS X 10.6.8
~/haskell_programs$ cabal update

~/haskell_programs$ cabal install text-icu

cabal: Missing dependencies on foreign libraries:
* Missing C libraries: icui18n, icudata, icuuc
This problem can usually be solved by installing the system packages that
provide these libraries (you may need the "-dev" versions). If the libraries
are already installed but in a non-standard location then you can use the
flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.

I found a post by a Windows user who had the same problem. Do I really need to go out and install those C libraries? Or are they 'misplaced' somewhere on my system?
Thanks.
If you have are using Homebrew, then this is the command that I use:
DYLD_LIBRARY_PATH=/usr/local/opt/icu4c/lib \
cabal install text-icu \
--extra-include-dirs=/usr/local/opt/icu4c/include \
--extra-lib-dirs=/usr/local/opt/icu4c/lib

How can I install this package on Ubuntu 20.04?
You aim to install the cabal-install package. This package has a dependency that here produces a problem: the zlib package.
This zlib package is essentially a thin wrapper around the zlib C library [wikipedia]. As the error says however, you did not install the zlib library, or at least not its package where one can develop with the zlib library.
We can install this by installing the libghc-zlib-dev software package, for example with:
sudo apt-get install libghc-zlib-dev
If we inspect the package details on Debian, we see that essentially this is a package that will install the zlib1g-dev package, the package to develop software with the zlib library. We can thus decide to install libghc-zlib-dev, or zlib1g-dev with:
sudo apt-get install zlib1g-dev

I'm using the Haskell Platform installed using homebrew (brew cask install haskell-platform), and cabal version 2.0.0.2. I have tried using sudo and deleting my ~/.ghc file
There was an issue with full 8.2.1 binary platform builds that's just been resolved: https://mail.haskell.org/pipermail/haskell-cafe/2017-October/127979.html
This was likely an instance of that.
(see also: GHC cannot find libraries on fresh install of Haskell-Platform)
This looks like a bug in Cabal 2 (or potentially GHC 8.2). See https://github.com/haskell/cabal/issues/4728. I'd recommend sticking to GHC 8.0.2 for the moment with either cabal 1.24 or Stack. I'm the case of Stack, the version won't matter, since it will use the Cabal version shipped with GHC.
I am trying to install wx by cabal install wx
Configuring wxc to build against wxWidgets 3.0

This problem can usually be solved by installing the system package that

--extra-include-dirs= and --extra-lib-dirs= to specify where it is.

I have also tried cabal install --extra-lib-dirs=/usr/lib/ wx but to no avail.
I have also tried all the suggestions in cabal install wx Missing C library
I am on archlinux and I have both wxgtk-3.0 and wxgtk-2.8 multilib and normal versions. I also tried reinstalling them.
I just ran into the same problem on Arch; when I tried running cabal with --verbose=3, it looked like libwx_gtk2u_webview-3.0 was present, but it was complaining about libwebkitgtk-1.0 being missing. After I installed the webkitgtk2 package, which provides libwebkitgtk-1.0, wxHaskell installed with no problems.
Try "sudo apt-get install libwxgtk-webview3.0-dev". It worked for me.
I am trying to install hmatrix on my Ubuntu Linux machine (don't know if this is necessary, but it may help) and no matter what I do it will not work.
I run cabal install hmatrix and get this:
Configuring hmatrix-0.13.1.0...

*** Sorry, I can't link GSL.
*** Please make sure that the appropriate -dev packages are installed.
*** You can also specify the required libraries using

cabal: Error: some packages failed to install:
hmatrix-0.13.1.0 failed during the building phase. The exception was:

Apparently the ExitFailure 1 thing is a leftover from the original program.
When I run cabal configure I get
Warning: 'hs-source-dirs: lib' directory does not exist.

*** Sorry, I can't link GSL.
*** Please make sure that the appropriate -dev packages are installed.

Any help would be greatly appreciated and thank you for reading.
You have to install the C libraries, something like libgsl-dev (or -devel), and libgsl itself, but that should be pulled in by the dev package. hmatrix is a binding to a C library, so you need that installed to be able to install hmatrix.
On my box, ghc-pkg describe hmatrix lists
extra-libraries: gsl lapack gslcblas
I'm not sure all of them are actually required for building hmatrix, but it wouldn't harm to also install the dev packages for lapack and BLAS (which may be something else than gslcblas on Ubuntu).
On Ubuntu some of the required libraries can be loaded with apt-get command. Try this,
sudo apt-get install libblas-dev libatlas-dev liblapack-dev
Referring to this file installation on Ubuntu is done using:
sudo apt-get install libgsl0-dev liblapack-dev
cabal install hmatrix

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.
