I am currently trying to use CmdArgs and I am running into some trouble.
The code is here on github and the error I am getting is this:

Any help would be greatly appreciated.
It turns out like usual I am an idiot.
The correct thing to do is to check the full path of a library; for my example the page for CmdArgs specifies that the library path for the module is System.Console.CmdArgs.

When I compile with GHC directly, it works fine, and libncursesw.so is present in /usr/lib. I'm on Void Linux. Any ideas where Stack is looking?
This looks like an issue with the bindist Stack has chosen for Void Linux - it normally guesses right, but it can cause issues on some distros. The tinfo6 variant tries to load libtinfo.so, since some distributions provide ncurses6 through that shared object file. You can try configuring the variant manually - you'll probably want standard. Stack will install a new GHC version if you do that, but it will change what shared object it tries to load for ncurses.
EDIT:
This was actually caused by an issue with GHC - if the distro links between the various ncurses files with a linker file, instead of an actual link, GHC won't follow it properly and instead complain that the file doesn't exist. The solution is to replace the linker file with a link to the target.

What I should do?
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.

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:
