Trying to install Yi fails because it fails to install vty.
When trying to install vty through cabal install vty, or cabal install after cloning the vty repo, I get error messages from undefined references, related to terminfo, such as this one.
/usr/local/lib/terminfo-0.4.0.1/ghc-7.6.3/libHSterminfo-0.4.0.1.a(Base.o): In function s4NX_info:
/tmp/ghc26691_0/ghc26691_1.o:(.text+0x20b1): undefined reference to cur_term
What does the error mean exactly?
The file /usr/local/lib/terminfo-0.4.0.1/ghc-7.6.3/libHSterminfo-0.4.0.1.a does exist. I tried in a sandbox, reinstalling cabal deleting its folders, yum-installing ncurses-devel, cabal-installing terminfo, yum-installing ghc-terminfo-devel, cabal-installing terminfo from a cloned repo, and combinations of those things (without really understanding what I was doing) to no avail.
I am in Fedora 20. Using Cabal 1.22.0.0 (installed an older Cabal with yum, then did cabal install cabal-install, and removed the yum's cabal). Cabal list terminfo right now shows 3 installed versions of terminfo (0.3.2.5, 0.4.0.0 and 0.4.0.1). ghc-pkg list shows v0.4.0.1 and 0.3.2.5 as installed (and not hidden) in the global database (I think. The one in /usr/lib64/ghc-7.6.3/package.conf.d)
I would appreciate some help to get Yi installed and to understand how to proceed with these issues. Thanks

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 just installed Haskell and have been trying to get it going, but when I tried to start it up, it does this:
C:\Users\isaac>cabal install
Warning: The package list for 'hackage.haskell.org' does not exist. Run
'cabal update' to download it.
cabal: Error reading local package.
Couldn't find .cabal file in: .
C:\Users\isaac>cabal update
Downloading the latest package list from hackage.haskell.org
It has been like that for 10 hours now. I don't know if it's even possible to see how much progress, if any, it's made, but it doesn't seem to be doing anything. The version is:
C:\Users\isaac>cabal --version
cabal-install version 1.24.0.2
compiled using version 1.24.2.0 of the Cabal library
All of this has been just to get Cairo working (on Windows).
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

I have no idea at all how in resolve this or where to even try. Has anybody trod this path before and do you have any advice or pointers?
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'm new to Haskell, trying to write a program for compiler construction class.
I installed the haskell-platform package on my ubuntu 13.10, and then (without messing around with anything after installing haskell platform) tried to run the following command:
$ sudo cabal install bnfc
which results with:
Resolving dependencies...
Configuring BNFC-2.6.0.3...
cabal: The following installed packages are broken because other packages they
depend on are missing. These broken packages must be rebuilt before they can
be used.
package process-1.1.0.2 is broken due to missing package
directory-1.2.0.1-508733a890139bbedb8aa76468431462
Failed to install BNFC-2.6.0.3
cabal: Error: some packages failed to install:
BNFC-2.6.0.3 failed during the configure step. The exception was:
ExitFailure 1
As I try installing package directory it says the package is already installed.
Can anyone help?
I also am using Ubuntu 13.10 with the haskell platform package, and bnfc installs for me.
There are a few things you can check....
Don't use sudo with cabal install (by default cabal installs packages in your own home directory, using sudo might be causing trouble by giving the wrong file ownerships, or perhaps trying to put files in /root, or even overwriting /usr stuff)
Rename ~/.cabal/ and ~/.ghc/, and rebuild them by running "cabal update" (You may need to re-add ~/.cabal/bin/cabal from the moved location after the move). These hold installed packages and their info.... Since you have a new vanilla install, these should basically be empty, although the meta info in them may be corrupt. (if for some reason this makes things worse, you can always restore the original directory.... If it solves the problem, you can delete the original .cabal and .ghc)
You can get more info about why a package isn't installing by doing the following
cabal unpack bnfc #This will download and unpack the source code
cd BNFC-2.6.0.3 #enter the newly created source directory
cabal configure #This checks that all system dependencies are met
cabal build #This builds the package
cabal install #This installs the package in ~/.cabal/
(You may have to iterate to another package if a dependency isn't met)
I think 2. may solve your problem, as the error message you showed implies that the build process is hooked on finding a very specific version of the directory package, rather than the latest one. This happened to me once and cleaning out .cabal solved the problem for me.
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.
