Let's assume the following procedure:
cd /home/user/experiment
git clone https://github.com/ryantrinkle/reflex.git
cabal sandbox init
cabal install --dependencies-only
Question:
At this point what packages will the sandbox in /home/user/experiment contain ? Will it contain the whole dependency hierarchy tree of Reflex ?
In other words, if Reflex is the root package then will the whole dependency tree of Reflex be compiled from scratch independently of what is installed already in the global package repository of cabal ?
I suspect yes, but I am not sure.
When I execute the above command sequence then the following packages are installed :
[vagrant#localhost reflex]$ cabal install --only-dependencies

This seems an awful lot.
Are these exactly the packages contained in the dependency tree of Reflex ?
I suspect yes, but I am not sure, hence this question.
Not quite. At the moment, anything in the global package database is also used by sandboxes. I believe future versions of cabal-install will restrict this to a few whitelisted core packages that ship with GHC (and that shouldn't/can't be replaced anyway).

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 have been trying to install gtk3 with cabal, following instructions on https://wiki.haskell.org/Gtk2Hs/Installation , with the exception I have replace gtk with gtk3, I downloaded the all in one bundle of gtk 3.6.4 (from: http://www.tarnyko.net/dl/gtk.htm) unzip it and added the location_of_files/bin to my path, running pkg-config --cflags gtk+-3.0 works ok, cabal install gtk2hs-buildtools correctly installs, but cabal install gtk3 stops with:

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.

And the gtk bundle I download have a libintl.h file in the include folder and a dll in the bin folder, I tried placing the files in almost every location I could think of but to no avail, i can’t think of anything else.
More details: I am running windows 7 x64 with haskell-platform 8.0.2 x64, and I really need this to work under windows for a project I am working.
I manage to install gtk by following the instruction in https://www.gtk.org/download/windows.php, installing MSYS2 and using pacman to install gtk library, ignoring only step 4. After installing the libraries I added to my path C:\msys64\mingw64\bin, and cabal finally compiled gtk3.
I did not like this solution cause it is one more mingw installation on my pc.
I've been trying to install the parsec library for haskell but I'm running in to a lot of errors. Im very new to haskell & cabal and i don't quite understand the output of the log file.
the output of the log file is here:
http://pastebin.com/6hPQN1W4
I tried installing the packages that the log file said that it could not find, but i keep getting errors when trying to install the packages.
I reinstalled cabal and also ran cabal update, but this did not resolve the issue
any help will be appreciated?
I suggest using stack tool with its stackage infrastructure. Please see http://haskellstack.org for more details.
You could try installing parsec in a sandbox.

TL;DR - Had an issue with bundle install. Read mkmf.log as mentioned in the error. The log had another error that I googled. Installed
necessary library. Afterwards, bundle install was successful.
I see that the errors point me to mkmf.log and where it's located. I open it up and check the error. Among other things it mentions the following on lines 2 and 3.
/usr/bin/ld: cannot find -lgmp
collect2: error: ld returned 1 exit status
I know from the error while during bundle install that it could be missing a library. So I search for a package called gmp. I find 2 libraries, one called libgmp10 and the other libgmp10-dev.
$ apt-cache search -n gmp

I search my installed packages to see if I need to get one.

Since libgmp10 is already there, I try installing libgmp-dev. Then I run retry installing my gems, and it works!

I can solve the problem by using sandboxes. But I'm interested to know if there is a nicer method resolve the dependency issue.
Update: Following a suggestion, I removed bytestring by ghc-pkg unregister --force bytestring, which broke some packages and am still not able to install aeson.
Following is the output of ghc-pkg list lists: http://lpaste.net/135108.
