How can I install the latest Haskell Platform on debian? - linux

I want to install the latest Haskell Platform on my Raspberry Pi.
Unfortunately my linux-fu is very weak. I can apt-get install haskell-platform which works, as far as it goes, but installs a very old version from the official package repository. Part of the code I want to compile only compiles against GHC 7.8.

You can get the latest GHC Debian Packages from http://deb.haskell.org
Instructions for installation here

As the comments discuss, the experimental suite contains (very) recent ghcs (including ghc release candidates).
You can install packages from there like so:
apt-get update
apt-get -t experimental install packagename
unstable also contains ghcs that are actually released.
And the generic linux binary platform also will work with debian.

Linux Installation libX11-devel

I am trying to build QT4 (porting from Redhat 5 to 7 with an upgraded gcc compiler) in RedHat 7 and I was getting an error saying X11/Xlib.h can't be found. Anyways, after doing some research most people said to install libX11-devel to get those x11 libraries. Since I am using an offline machine I can't do "apt-get" type commands and have to manually install RPMs. So, I went to my RH-7 installation DVD and got "libX11-devel-1.6.3-3.el7.x86-64" (I have 64 bit OS) and tried to install using "yum install libX11-devel-1.6.3-3.el7.x86_64" and I am getting dependencies errors. It's saying
...Requires: pkgconfig(kbproto)
...Required: pkgconfig(xcb)
...Requires: pkgconfig(xproto)
...Requires: pkgconfig(xcb) >= 1.1.92
So, here are my questions.
1) when it says "pkgconfig(kbproto)", is it saying find the "kbproto....RPM" and do a "yum install". In my dvd I only have "xorg-x11-proto-devel-7.7.13.el7.noarch.rpm". Do I have to somehow find "xorg-x11-proto......x86_64.rpm" since it's a 64 bit machine?
2) Is there a difference between "yum install" and pkgconfig "install"? Are there any other installation variants in Linux?
3)For an offline machine, Is there anyway I can get all the dependencies and install everything at once ?
4) Why is it saying "xcb" requires twice. If I just get a xcb...rpm version above 1.1.92 can I just install it once?
Before actually answering the questions, I am going to suggest to see if you can get the latest version of the packages. The packages on the installation DVD may be really out of date and contain known vulernabilities, and other bugs. Can you use yumdownloader - in an online environment - to download the latest version onto a separate DVD and use that as the installation source? See https://access.redhat.com/solutions/10154 for more information.
To answer the questions themselves:
Requires: foo can refer to a package foo or a "feature" foo. pkgconfig(kbproto) is a "feature" (or virtual requires). You can use yum/rpm to see what provides this. On my Fedora box, for example, rpm -q --provides xorg-x11-proto-devel shows that this package indeed provides pkgconfig(kbproto).
As for x86_64 vs noarch, it doesn't matter. noarch packages work everywhere. Other packages are restricted to the platform. So x86_64 only works on intel/amd x86 64-bit machines. Installing noarch should be fine in your case. If you only had a i686 package, though, that wouldn't be sufficient. You would have to find a x86_64 or noarch package.
Yes, there's a big difference between yum and pkg-config. They do completely different things. One is a system tool for installing RPM packages. The other is a tool for developers for using the right headers and compiler flags. If your concern is finding/installing RPMs, do not use pkg-config directly.
Do you have access to an online machine that can access the RHEL 7 yum repositories? On that machine, do something like this:
mkdir rhel7-packages
cd rhel7-packages
yum provides '*/X11/Xlib.h' # make a note of the package that provides this file. it's libX11-devel on Fedora here
yumdownloader --resolve libX11-devel # download libX11-devel and all dependencies not installed on the system
Then copy/install the RPMs on the machine without internet access.
It's probably printing out xcb twice because it's two different requirements. The unversioned requirement will be satisfied if you install any verison of xcb. The versioned requirement will only be satisfied if you install 1.1.92. If you install 1.1.92, it will satisified both the requirements.
1.
You have to resolve the dependency on the system where you are building your package. This means you need to have those dependencies installed, inclusing libX11-devel. To do that, download the RPMs manually from EL7 repos to local disk and run this:
$ mkdir -p /tmp/libX11_dep_rpms && cd /tmp/libX11_dep_rpms
# Download all dependencies from here. All your packages should be available here:
# http://mirror.centos.org/centos-7/7/os/x86_64/Packages/
# Then install
$ yum localinstall *.rpm
# After this you should be able to build your qt4 package, provided all dependencies are resolved. Otherwise, repeat the procedure for all dependencies
# If you can't download packages, then you need to create a FULL DVD ISO that will contain all packages.
2.
pkgconfig ensures that a requirement is coming from a particular build that provides a particular version of the library. Here are some detail.
3.
Get the Everything ISO from EL7.
4.
This has to do with the pkgconfig and library versions.

Fedora - Reinstalling GMP with C++ support

I'm trying to install a library that uses gmp and am running the ./configure on it.
So far, I've gotten past several snags, such as requiring gcc, g++, and m4 by using:
yum install gcc
yum install gcc-g++
yum install m4
Now I'm getting this error:
checking for the GMP library version 4.1.3 or above... no
configure: error: Cannot find GMP version 4.1.3 or higher.
GMP is the GNU Multi-Precision library:
see http://www.swox.com/gmp/ for more information.
When compiling the GMP library, do not forget to enable the C++ interface:
add --enable-cxx to the configuration options.
As such, I tried both installing and updating gmp using yum:
yum install gmp
yum update gmp
Install tells me it's already installed and is v. 5.1.2
Updating says there's nothing to update.
I went to the gmp site and it is currently v. 6.0.0
I downloaded it and ran configure (using --enable-cxx), make, and make install.
Yet, nothing has changed. It still says I have v. 5.1.2 and the configure for the library still says it can't find 4.1.3 and above / try enabling c++.
The gmp files (such as gmp.h) are being placed in /usr/local/lib and /include
I've been at this for hours without any progress. I'm rather new to linux so I imagine there's something I just don't know about.
Am I not installing 6.0.0 correctly to overwrite the already installed one?
Or is there a way to reinstall the original with the c++ option?
Any help would be appreciated. Thanks.
dnf install gmp-devel resolved this for me on rhel
When you manually install something, as you have, it doesn't get installed in the normal /usr/lib directory and therefore it doesn't overwrite it. This is a good thing. In general, you shouldn't mess with files installed by the package manager. (Except in the case that they are config files that are meant to be edited.)
When you install manually, it is installed to /usr/local/lib. Fortunately, GCC and other compilers don't care which directory something is installed in, they will find it (when it's in standard places like /usr/* or /usr/local/*).
Just include the C++ header and add the correct -l library flag.
I figured it out.
Under the --help section of the ./configure for the library I was trying to install, there was actually a feature just for this:
--with-gmp-include=DIR
--with-gmp-lib=DIR
Using these, I was able to get it to install.
Thanks for the help.
I think I was too focused on trying to update the system install of gmp.

Cabal can't determine GHC version

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
The Glorious Glasgow Haskell Compilation System, version 7.4.2
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)

How to install Haskell Platform on Linux Debian Wheezy?

Initially I thought I would get install Haskell with couple of commands using apt-get but its seems somehow complex.
As I look at the haskell org download page, I downloaded haskell-platform-2013.2.0.0.tar.gz. Then next step is somehow confusing. It ask to install GHC before installing platform but at the same time if one opens GHC download page , it shows some warning e.g Stop ! ..... we recommend installing the Haskell Platform instead of GHC.
Please guide me how to install Haskell on Debian Wheezy. Can we build a .deb installation package from this package ?
$ sudo apt-get install haskell-platform [haskell-platform-doc]
On Debian Jessie, the above will install an outdated Haskell distribution. The latest can still be installed by downloading the "generic" Linux tarball for the Haskell platform.

Error building haskell llvm bindings on Linux

I built llvm 3.0, downloaded from here. I did:
./configure CC=gcc CXX=g++ --enable-shared
sudo make -j5 -s install
Next, I cloned the LLVM bindings from here. I am trying:
runhaskell Setup configure
But I get:
Configuring llvm-3.0.0.0...
Setup.lhs: At least the following dependencies are missing:
llvm-base ==3.0.*, type-level -any
I am running Linux Mint 64-bit (equivalent to Ubuntu 11.0). GHC is 6.12.3. I tried a cabal install but apparently the llvm version is too old to run some examples (am I mistaken?).
What am I doing wrong?
Bryan recently split the llvm package in two, that split has not yet made it to hackage. So if you don't want to simply cabal install the hackage version,
install the type-level package (cabal install should work fine)
cd into the base subdirectory of the llvm-repo, install llvm-base
cd into the llvm directory, install
I have not tried it, so it might not work, but usually Bryan's repos are buildable, so there's a good chance that it does.
