I'm trying to follow along with the Plutus Pioneer lectures, and I'm getting this error
My system:
Ubuntu Linux Docker image running on MacOS.
I installed the Haskell package on the image from here: https://www.haskell.org/platform/linux.html
using this line in my Dockerfile: RUN apt-get install -y haskell-platform
This seems to install Cabal version 2.4.
When I clone the code repository for the lectures: https://github.com/input-output-hk/plutus-pioneer-program and then go to the week01 directory and try cabal build like in the lecture, I get dependencies not found errors. The first missing dependency is 'aeson', which seems to install if I run cabal install aeson.
The subsequent build attempts fail on dependency 'base' being the wrong version.
Then I thought maybe if I update Cabal to version 3.4 it might help, so I tried cabal install cabal-install, but this also has errors:
Theexception was:ExitFailure (-9)
This may be due to an out-of-memory condition.
So I googled some more and tried this command line: cabal install --ghc-options="+RTS -M600M" -j1 cabal-install from here https://stackoverflow.com/a/46148345/52236
This seems to get further, but now I'm at this error:
ghc: panic! (the 'impossible' happened)
(GHC version 8.6.5 for x86_64-unknown-linux): heap overflow
If anyone has any idea how to fix this it would be appreciated. Do I need to add more RAM to my Docker Ubuntu image? It currently has 1.9GB of memory and 1.7GB free.
thanks,
m
I fixed this by increasing the RTS param:
cabal install --ghc-options="+RTS -M1000M" -j1 cabal-install
Well, actually it compiled everything, but cabal --version still says 2.4, not 3.4. There was this warning too:
Warning: could not create a symlink in /root/.cabal/bin for cabal because the
file exists there already but is not managed by cabal. You can create a
symlink for this executable manually if you wish. The executable file has been
installed at /root/.cabal/bin/cabal

I am trying to install Elm and the instructions are to install Haskell and then
sh> cabal update
sh> cabal install cabal-install
sh> cabal install -j Elm elm-repl elm-reactor elm-get
When I do, the cabal-install installation installs text-1.2.0.0 which conflicts with the text-1.1.0.0 which uniplate requires so uniplate and its dependents fail to install. Text-1.1.0.0 is installed and present but is rejected in favour of text-1.2.0.0, even though the target needs text-1.1.0.0.
Is there a way to insist that cabal use text-1.1.0.0?
Is there a way to get text-1.1.0.0 and text-1.2.0.0 to co-exist?
Is there a way to convince uniplate that it can accept text-1.2.0.0?
Or a way to make uniplate (or cabal) believe that version text-1.1.0.0 is actually installed? Would that even work?
When I explicitly try to install version 1.1.0.0 of text, I am told that a reinstall would break other packages. Apparently it is a downgrade and not a co-installation. cabal does not seem to have an option to allow to me install two versions of the same library at the same time.
If I uninstall Haskell and all the libraries and then re-install Elm (without installing cabal-install so I don't get text-1.2.0.0 installed so there is no clash), I get 100 or so lines of

Thank you.
Edit
Installing in a sandbox changes the outcome only by degrees: text-1.1.0.0 does not clash with text-1.1.0.0 but still can not be loaded (despite being installed) and still remains the unsatisfied dependency.
blaze-builder is first to fail with cannot satisfy -package-id text-1.1.0.0-9bd69e9ace700e05fb08e463086bc383 yet the same log earlier stated [_12] trying: text-1.1.0.0/installed-9bd... (dependency of Elm-0.13) without apparent error or complaint.
cabal list shows both text-1.1.0.0 and text-1.2.0.0 as installed.
Installing blaze-builder separately looks the same. Dependency resolution shows
[_56] trying: blaze-builder-0.3.3.4 (user goal)
[_57] next goal: text (dependency of blaze-builder-0.3.3.4)
[_57] trying: text-1.1.0.0/installed-9bd...
[_58] done
All looks good but later, same log has
<command line>: cannot satisfy -package-id text-1.1.0.0-9bd69e9ace700e05fb08e463086bc383
(use -v for more information)
The ghc command line already had the -v flag and trying to re-run the command line copied from the log, with more -vs, gives an error with "can't find a package database at
dist/dist-sandbox-ad0bcd57/package.conf.inplace".
No package.conf.inplace seems to exist.
Further edit
On the Elm install page is a link to a BuildFromSource.hs script that is also supposed to work installing Elm. In the time that it took for that script to run and fail to work, I managed to install leiningen, node, npm, grunt and Clojure. I am now further along the road to getting Clojurescript installed in about 20 minutes than I am in getting Elm installed in nearly a week.
Elm looked really interesting but it is playing way too hard to get.
Thanks again to everyone who tried to help.
* Edit *
I finally got it.
Every executable installed by the installer at http://elm-lang.org/Install.elm caused a segfault.
The "Build from source" option at the same page did not work because the dependencies either stepped all over each other or could not get themselves straight in the first place.
The ghc at http://new-www.haskell.org/downloads/osx needs a later version of Mac OS than I have. (A link to older versions would not have gone astray.)
The solution (and it is obvious in retrospect) was to port install haskell-platform and port install hs-cabal-install and cabal install Elm .... I did have to run one of those installers twice because it could not find hackage.haskell.org (How is that a 'user' error?) but my hello-world.elm now compiles.
Thank you all again.
It looks like some dependency issues with elements you already have installed. You will probably need to install it in a sandbox.
First, update to the latest version of cabal:
$ cabal update
$ cabal install cabal cabal-install
Next, make sure you have the installed version of cabal on your $PATH.
$ which cabal
> /path/to/cabal/bin/cabal
If it says something like /usr/bin/cabal you will need to export cabal to be on your $PATH. For me this is `/home/username/.cabal/bin
$ export PATH=/path/to/cabal/bin/cabal;$PATH
Run which cabal again and ensure it is pointing to that path.
Now that you have the latest version of cabal. Run the following:
$ mkdir elm
$ cd elm
$ cabal sandbox init
This will initialize a sandbox where dependencies are completely independent of your other installs. Within this directory, you should be able to install the elm platform by running:
$ cabal install Elm elm-repl elm-reactor elm-get
These will be installed in a sub-directory called .cabal-sanbox/bin/ For convenience, you will probably want to add this to your $PATH so you can run the executables from any directory.
Hope this helps!
I am currently trying to update Cabal (1.14.0, cabal-install at version 0.14.0) by doing
cabal install cabal-install
However, this gives me an ExitFailure1 with the error
setup: The program ghc version >=6.4 is required but the
version of /usr/bin/ghc could not be determined.
But I'm definitely running a version of GHC that is greater than that.
$ /usr/bin/ghc --version

It might be important that I'm on OSX 10.8 and that I installed Haskell through the Haskell Platform download for Mac.
Does anyone have advice on how to fix or work around this issue? I haven't been able to find any documentation on this problem.
Since you're on a Mac, why not try installing the excellent Homebrew package manager? Add /usr/local/bin to your PATH, and then it's just brew install cabal-install.
You can even brew install ghc haskell-platform.
To upgrade the package list, use brew upgrade, then you can see what needs updating with brew outdated and update them with brew update.
Of course, you can name individual packages to update also, and specify versions of packages. Homebrew keeps the "recipes" (Ruby scripts) for package management in its own git repository (by default in /usr/local).
Then you can get on with what you really wanted to do in the first place...write some code! (or build, in your case)
hi i'm trying to install, (without having to update or install the latest compiler),reactive-banana-wx and one of the requirement's are failing
cabal install reactive-banana-wx
and heres the error
Configuring wxc-0.90.0.4...
setup: failed
cabal: Error: some packages failed to install:
reactive-banana-wx-0.6.0.1 depends on wxc-0.90.0.4 which failed to install.

wxc-0.90.0.4 failed during the configure step. The exception was:
ExitFailure 1
wxcore-0.90.0.3 depends on wxc-0.90.0.4 which failed to install
when i try to cabal install wxcore ,wx or wxc they all say failed and point towards wxc being required.
here's the error
cabal install wxc

ghc -v
Glasgow Haskell Compiler, Version 7.0.4, for Haskell 98, stage 2 booted by GHC version 7.0.4
I've got the same error trying to install phooey with ghc 7.4.1 on Debian tonight. The reason is a bug in the package wxc-0.90.0.4 and it should affect all wxHaskell-based packages. You can fix it, there is no need to downgrade your wxc package...
The easiest way to reproduce it is to do
cabal install wxc
or
cabal install glade
It might be a good idea to make sure that all prerequisites are in place, before you do it. wxc depends on a number of cabal and Linux packages and all of them should be installed and compiled... I did it in the most stupid way possible, just by running
cabal install wxc
and reading error messages which it spills out. This sweetie usually tells you what it wants... For instance, if it complains about cabal package x, just do cabal install x. If it complains about Linux package y, then use your Linux package manager and install the development version of this package, which is called normally lib<y>-dev in Debian. So, for instance, if
cabal install wxc
gives you an error saying that package gtk+2.0 is missing, you want to do
apt-get install libgtk2.0-dev
The same story with cairo, glade2 and other GTK-related libraries
When you are green with all prerequisites, you want to install wxWidgets-2.9, which is currently in the Development stage... so, it doesn't have any binaries for Linux and you should build it yourself. Download the source code from wxWidgets website and build it. It is pretty easy to do, just:
untar/unzip the source code to your favorite directory
run ./config
run ./make
If you are on wxc-0.90.0.4, at this moment you should encounter our little bug... To keep the long story short, it is in the file eljpen.cpp, which you can find in
~/.cabal/packages/hackage.haskell.org/wxc/0.90.0.4/wxc-0.90.0.4.tar.gz
Open the archive, go to the line 159 in the file and replace *_ref = NULL; with _ref = NULL or anything else what makes more sense. Then recreate the archive in the same place with the fixed eljpen.cpp file in it.
run ./make
It should work now.
run sudo make install (normally, you should have root privileges to insatll wxWidgets library...).
after it is done try to do
cabal install wx
again. It should be working now. I guess, after that you can enjoy your reactive-banana-wx, wxHaskell, phooey, etc.
PS http://sourceforge.net/tracker/index.php?func=detail&aid=3576397&group_id=73133&atid=536845. Why didn't I find it earlier? :/
I'v solved this problem on Lubuntu 12.10 so:
sudo cabal info wx
Synopsis: wxHaskell
Versions available: 0.11.1.2, 0.12.1.4, 0.12.1.5, 0.12.1.6, 0.13.2,
0.13.2.1, 0.13.2.3, 0.90, 0.90.0.1 (and 11 others)
I picked out different versions of wxHaskell, but only 0.13.2.3 was right.
sudo cabal install wx-0.13.2.3
...and everything has compiled and installed. Then I could install:
sudo cabal install reactive-banana-wx -fbuildExamples
That's no depends on the version of your Glasgow Haskell Compiler or the sort of your Linux.
When I tried to load a .hs in ghci, it failed on the line:
import System.Random
Message:
Could not find module `System.Random'
Use -v to see a list of the files searched for.
I remember it worked yesterday and all of a sudden today it does not work.
This problem only occurs on Ubuntu 12.04 LTS, GHCi 7.4.1 , when i tried this on windows haskell platform and other linux machines i worked.
I tried to use
sudo apt-get remove ghc
sudo apt-get install ghc
to remove and re install ghc, but however the problem persists.
Could someone help me? Thanks
You must install the random package. You can probably get it from your package manager (as something like libghc-random-dev or similar), or you may cabal install random.
Edit in 2021 These days, cabal install is not the way. Instead, use cabal init to create a package and list random in your build-depends field. Compilation can be performed with cabal build (just build) or cabal run (to execute the result); interactive use is available via cabal repl.
I am trying cabal install glib-0.12.3 under my Ubuntu 11.10 using cabal-install 0.10.2. However, it shows the following error messages:
setup: The program gtk2hsC2hs version >=0.13.5 is required but the version
found at /usr/bin/gtk2hsC2hs is version 0.13.4
cabal: Error: some packages failed to install:
glib-0.12.3 failed during the configure step. The exception was:
ExitFailure 1
After half an hour's search, I cannot find where this gtk2hsC2hs is. I dug into places like http://code.haskell.org/gtk2hs/tools/c2hs/, but could not seem to find the right version.
How could I upgrade my gtk2hsC2hs? Thanks!
It's part of the gtk2hs-buildtools package.
$ cabal install gtk2hs-buildtools
(maybe with the --global flag, depends on how you want to install packages in general) should provide you with the newest version that should be able to build the latest gtk2hs packages.
Since the old gtk2hsC2hs is in /usr/bin, make sure that the new one is either installed there (replacing the old) or in a directory appearing before /usr/bin in your $PATH. A default cabal install installs executables (on Linux) in $HOME/.cabal/bin, so it would be a good idea to have that the first directory in the $PATH.
