I am on Ubuntu and this is the error message that I keep getting. This library is a dependency for sdl2. Is there some other external library I need to install?

How can Haskell be compiled to Javascript using GHCJS and Haskell Stack?
I have the current version of Haksell Stack 1.5.1.
I can initialize a GHCJS project with this command: stack new ghcjsSetup ghcjs
Once in the project directory I try following the Stack documentation for GHCJS.
I create a stack.yaml file and edit it to match the example from the documentation so that is looks like this.
resolver: lts-7.19
compiler: ghcjs-0.2.1.9007019_ghc-8.0.1
compiler-check: match-exact
setup-info:
ghcjs:
source:
ghcjs-0.2.1.9007019_ghc-8.0.1:

sha1: d2cfc25f9cda32a25a87d9af68891b2186ee52f9
Following the documentation further I try to install and boot GHCJS with this command:
stack setup
This command produces an output which ends with an error.

This will not interfere with any system-level installation.

You are missing the libtinfo library which is part of ncurses. Depending on your environment try something like:
sudo apt-get install libtinfo-dev
As an aside, getting all the pieces that ghcjs needs to build successfully is tricky and not well documented as of September 2018. One might hope that as the project matures it will get easier to install, and that a binary package will be produced. Know that you are not the only person who has these issues. It takes some patience and trial-and-error to get ghcjs working right now.
Others have had success using nix, I did not.
Building project dependent on glib fails on lts-7.8 and later after Cabal becomes 1.24.1.0.
Steps to reproduce
Add glib to a project's .cabal file
build-depends: base
, gtktest
, glib
Run following commands
stack install gtk2hs-buildtools
stack build
Result
The following error occurred

I thought that Cabal-1.24.0.0 in the ghc-8.0.1 global package was causing problems, and succeeded building it after installing Cabal-1.24.1.0 in ghc 's global package.
However, this method is difficult for beginners and I do not think the right solution. How is the correct way to solve it?

I found that this messages is because of glib.cabal files bug at glib-0.13.2.2, so when I try to install glib separately, I edit glib.cabal (remove -D___attribute__(A)= option on cpp) and install clearly.
However, when I try to install it using stack, stack install gtk command always takes Hackage one instead of installed glib package.
For short, therefore, my question is, how can I using separately installed glib? Or, is there any way to modify packages .cabal file while installing it, using options or whatever?
Stack lets you use a dependency from a local directory, or a github repo. So feel free to fork the project, do the fixes, maybe even do a PR, and then put this into your stack.yaml under "packages" section:
- location:
git: https://github.com/user/repo
commit: a1b3559090e9c75ce1d46969085fe4f918b2fa82
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?

cabal: Error: some packages failed to install:
I tried ghc-pkg unregister for all the dups, but that didn't help.
I also tried ghc-pkg check and that doesn't return anything, ever.
I tried starting over, removing all the local databases including $HOME/.cabal/, then reinstalling cabal-install and this is where I'm currently at.
This is the result after removing everything, and reinstalling cabal-install:

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.
