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On Debian Jessie, the above will install an outdated Haskell distribution.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.

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 The packages on the installation DVD may be really out of date and contain known vulernabilities, and other bugs.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.
I've Redhat 7.2 running Cinnamon, and hate the docks provided, how come I can't resize the area a widgit is allocated? All apps are jammed into half the dock.
Drives me to compile cairo-dock from source as it isn't an ibm redhat blessed package.
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
...
-- checking for module 'wayland-client>=1.0.0'
-- package 'wayland-client>=1.0.0' not found
-- checking for module 'gtk+-3.0>=3.4.0'
-- package 'gtk+-3.0>=3.4.0' not found
so I find gtk version is 3.14.13-16.el7 using yum list installed "gtk*"
I downloaded gtk 3.4.4 and compiled it and follow the INSTALL provided, sudo make install, which completes with no errors
rerunning cmake gives me the same error, so I'm wondering if I had to remove 3.14? I'm not really sure how best to proceed and thought it best to get some advice. I'm not really in the mood to break things. Thanks for your time and consideration.
Calvin, I'm also IBMer and installed RHEL7.2 from IBM's image.
I could successfully download the sources and install Cairo Docker and respective plugins.
I followed the instructions in this page here:
Glx-Dock - Generic:Compilation
First, install all dependencies below from official IBM repository.
I used the same package names for the Fedora dependencies and some may NOT exist for RHEL. Therefore, some plugins won't be available by fetching dependencies from official repository only - but the Cairo Docker will work.
sudo yum install cmake make pkgconfig gcc gcc-c++ gettext glib2-devel\
cairo-devel librsvg2-devel dbus-glib-devel libxml2-devel libXrender-devel\
mesa-libGL-devel mesa-libGLU-devel pango-devel libXxf86vm-devel\
libXtst-devel libXrandr-devel libX11-devel libcurl-devel gtk3-devel\
vte3-devel lm_sensors-devel libxklavier-devel libexif-devel\
libetpan-devel gnome-menus-devel alsa-lib-devel libical-devel\
upower-devel libzeitgeist-devel
Untar the packages and build with the commands described there except that you need to force the lib64 in both main and plugin builds with:
cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DFORCE_LIB64=yes
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.
A friend and I are interested in training the tesseract-OCR engine for a CV project. We tried using some wrappers such as PyTesser and pyocr, but the results are currently not as accurate as we need them to be. As such, we want to try training the tesseract to perform better for our purposes (i.e. identifying text on food labels), but are having some trouble installing the training tools.
What we've tried:
Looking on the google code website, the 'Compiling' page on the tesseract's google code wiki says the training tools are only available on version 3.03. However, the google code 'Downloads' page for tesseract-ocr only has the materials for 3.02. The bottom of the 'Compiling' page also has some comments about installing version 3.03 on Windows and OSX, but no comments yet for Linux users.
There also appears to be some sort of 3.03 source package for Ubuntu but we're not sure how to access it on our computers and the 'Compiling' page says we need to run these commands:
make training
sudo make training-install
We've also found a google group thread about tesseract 3.03 but again it seems like these posts do not include advice for Linux users (unless we missed something during the initial read).
Is this actually a really simple command-line install problem? Or, is there a way train tesseract with 3.02 (which we currently have installed)? Have we been looking at the wrong places for information?
Any advice or links to instructions for installing tesseract-ocr 3.03 for Linux distributions would be greatly appreciated! Thanks.
Tesseract can directly be installed in Ubuntu 14.04 using
sudo apt-get install tesseract-ocr
I don't have any idea if you can do it in older version of Ubuntu because the repo might be updated in later version of Ubuntu.
I had an aws ubuntu 14.04 instance.
when I tried installing Tesseract with
sudo apt-get install tesseract-ocr
It retuned package not found
But this worked for me.
sudo apt-get update
sudo apt-get install tesseract-ocr
Ubuntu is a debian based Linux distribution. The tesseract package you find will most likely be a debian package which will contain tesseract and the required default language files to allow you to run/train tesseract. You do NOT want the source package -- unless you just want to compile it yourself -- no need. You will not have to build tesseract, you just need to install the package. First, it appears you are new to Ubuntu, so please ready InstallingSoftware. It can be as easy as opening up an x-term and issuing the command apt-get install tesseract-pkgname (note: that means whatever the package name is).
There is no shortcut, take the time to understand whether you have a .deb package on your box that need to be installed or whether you are installing from a remote repository. The link above explains how to handle both.
Here is a specific Ubuntu thread dealing with installing tesseract Tesseract 3.0 + Ubuntu 10.04 Installation Guide Hope that helps. Tesseract is very good software.
I don't have any instructions for building Tesseract 3.03 for Linux specifically (I'm on Mac), but here's a link to download the source code for the 3.03 release candidate: https://tesseract-ocr.googlecode.com/archive/3.03-rc1.tar.gz
First run below command
sudo apt-get install tesseract-ocr
It will install tesseract version 3.04
Run below to update the tesseract
sudo apt-get --only-upgrade install tesseract-ocr
It will update tesseract to 4.1.3
I need to build yum package in ubuntu for Stress 1.0.2 application in ubuntu . I am i beginner and provide me Links to download and learn building an yum installer package.
Beware that RPM/yum packages rarely work properly on Ubuntu/Debian systems.
If you want to try it anyway, you can use the alien tool to convert the RPM into a DEB, then you can use dpkg or gdebi-gtk to install it. The homepage of alien is http://kitenet.net/~joey/code/alien/ and you can install it with apt-get install alien.
Edit: why do you want to use the RPM package given that you can install stress and stressapptest from the Ubuntu repositories?
