I am having a really hard time getting OpenCL working in Trusty or Mint 17. Im using ppa:xorg-edgers, tried updates and even nvidia-340.
sudo apt-get install nvidia-331 nvidia-331-uvm nvidia-cuda-toolkit nvidia-cuda-dev opencl-headers nvidia-opencl-dev clinfo
Rebooting and then
babak#ASUS-G750JH:~$ clinfo
clinfo: /usr/lib/x86_64-linux-gnu/libOpenCL.so.1: no version information available (required by clinfo)
I: ICD loader reports no usable platforms
I have tried this on two Intel based systems with Nvidia GPU's a desktop with a GeForce 280, and a laptop with GeForce 780M with a physically disabled Optimus by the Asus, it only has the Nvidia GPU. A G750JH.
Has anyone done this successfully? Can I roll back and remove the PPA and use the default repo's, would that even make a difference?
For the xorg-edgers nvidia-346 packages, I get it working by installing also the nvidia-opencl-icd-346 package and its dependency ocl-icd-libopencl1.
Im not 100% sure what the issue was, but seems that the ppa:xorg-edgers, may have an issue. Whatever is broken the process below fixes the issue and results in both Cuda and OpenCL working with Nvidia and Ubuntu 14.04 x64

I need to install QT 5.10 on my ubuntu docker container. Compiling from source is out of question because it takes hours and my computer almost fried 2 times trying to do it until it ran ut of memory.
Does the QT installer from https://www.qt.io/download installs the libs for 5.10? If so, is there a way to install in a non graphical way? Since I'm in docker, I need an aautomated way to install it, but the .sh that is downloaded from the website is hundreads of megabytes long, so I can't read it to see if I can pass commands to automatically install it.
I think there's a PPA with qt available but I need a really thrustworthy source to get these libs. Debian is even worse in up to date packages.
Try in light of: headless unattended installation
As for Qt5.9.1
apt-get -y update
apt-get -y install build-essential libgl1-mesa-dev libassimp-dev libfontconfig1 libdbus-1-3 wget
wget http://download.qt.io/official_releases/qt/5.9/5.9.1/qt-opensource-linux-x64-5.9.1.run
chmod +x qt-opensource-linux-x64-5.9.1.run
./qt-opensource-linux-x64-5.9.1.run
I'm a newbie to Linux and try to install the latest R version on my Raspberry.
My Raspberry runs on Wheezy 7.8.
I followed instructions on CRAN, so I
added
deb http://cran.rstudio.com/bin/linux/debian wheezy-cran3/
to /etc/apt/sources.list
ran apt-get update which was successful and gave me only a "signature error" for the public key as pointed out on the CRAN-site
ran apt-get install r-base
But the result of the last command is
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
r-base : Depends: r-base-core (>= 3.1.2-1~wheezycran3.0) but it is not going to be installed
Depends: r-recommended (= 3.1.2-1~wheezycran3.0) but it is not going to be installed
Recommends: r-base-html but it is not going to be installed
Recommends: r-doc-html but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I tried to install R-2.15 before and then run the above commands. R-2.15 could be installed successfuly, but I'd need R-3* really.
I did browse the web, but couldn't find any useful hints for my specific problem, so I appreciate any support you could give me.
Thanks!
If it is of any use:

I had the same situation and decided to install that from the source code instead of install R from the repository(apt-get command).
Here is the command I run on my Raspberry Pi 2.
I could install and run R(3.1.2) sucessfully.
It might not be complete answer for you because I might already installed the library like gcc you did not have before. If you encounter the other issue, please let me know. I would like to solve it.
Just as a side note on this topic, because sudo make install process took a long time(maybe over a hour. I'm not sure because I feel asleep before I knew it...), I recommend you to do this when you have enough or before going to sleep like me.
wget http://cran.rstudio.com/src/base/R-3/R-3.1.2.tar.gz
mkdir R_HOME
mv R-3.1.2.tar.gz R_HOME/
cd R_HOME/
tar zxvf R-3.1.2.tar.gz
cd R-3.1.2/
sudo apt-get install gfortran libreadline6-dev libx11-dev libxt-dev
./configure
make
sudo make install
R
The cause of your problem is likely that the cran repository provides armel versions of the packages, and not armhf (which is the expected architecture for your RPI). If this is right, then you have two solutions:
The first work-around could be to download the armel version of the packages and then force their installation despite the architecture mismatch. It is supposed to work according to the Debian wiki, although you may experience performance issues:
The CPU in the Raspberry Pi implements the ARMv6 ISA (with VFP2) and
is thus incompatible with the Debian armhf port baseline of ARMv7+VFP3
and ARM hardware-floating-point ports for other distributions, which
all have the same baseline. It is compatible with Debian armel
(armv4t, soft(emulated) FP), but floating-point tasks will be slow
when running the Debian armel port.
To do that, you can try to reinstall the packages by specifying the armel architecture, for example:
apt-get install r-base:armel
If it doesn't work this way, you can otherwise download the packages from http://cran.r-project.org/bin/linux/debian/wheezy-cran3/ and install them manually using a commandline like:
dpkg --install --force-architecture xxxx_armel.deb yyyy_armel.deb zzzz_armel.deb
The other solution would be to compile R from its source.
I solved my initial question by upgrading Wheezy to Jessie. I am not an expert, but Jessie seems to be the current testing version of Debian, while Wheezy is the stable release - see here.
For upgrading, I followed the instructions here, or here, or here. Note: Upgrading takes quite a while and during the process you're required to answer some questions.
A word of caution though: Jessie is still testing and some people recommend not to use it yet, for a discussion see e.g. here.
I did set it up completely from a new completely new image, and it works well.
After having upgraded to Jessie I installed R-3.1.1. using
sudo apt-get install r-base
And I'd like to thank all those who have answered my question and given alternative ways of solving the problem above.
I'm able to install R-3.1.2 into raspbian using answer from teramonagi. I confirm it can install successfully on Raspberry Pi model B/B+.
However, before you can actually use R (install packages and run some R scripts), you have to increase the swap file size for Raspberry Pi due to lack of RAM (This service works very similar to page file in window, it kicks in when RAM usage is high). You can configure it by edit one of the config file by enter command below in LX terminal.
sudo nano /etc/dphys-swapfile
CONF_SWAPSIZE=100 #(change 100 to 512 or 1024, up to you, save the file)
sudo /etc/init.d/dphys-swapfile stop
sudo /etc/init.d/dphys-swapfile start #(restart swap file service with new swap file size)
Take note though, some users argued that increase swap file size can actually ruin your SD card. So apply this change at your own risk. I've been running my Pi with this configuration for my R automation for 1 month now. No issue so far.
Hope this helps.
Edit: If you are using model B/B+, i recommend to configure swap file size first then compile R.
That's what I've done to update my r-base on wheezy:

What is the best way to upgrade atom on Linux Ubuntu ?
I install atom using official doc
git clone https://github.com/atom/atom
cd atom
script/build
sudo script/grunt install
I created the following script to update my atom on Ubuntu 14.10.
#!/bin/bash
# Update atom from downloaded deb file
rm -f /tmp/atom.deb
curl -L https://atom.io/download/deb > /tmp/atom.deb
dpkg --install /tmp/atom.deb
echo "***** apm upgrade - to ensure we update all apm packages *****"
apm upgrade --confirm false
exit 0
The file atom_update is executable and needs to be called using su:
sudo ./atom_update
The above works, but nowadays I use the following:
sudo add-apt-repository -y ppa:webupd8team/atom
sudo apt -y update
sudo apt -y install atom
apm install \
file-icons \
tabs-to-spaces \
trailing-spaces \
xml-formatter
With the above setup
sudo apt -y upgrade
will update an installed atom to the latest version. The ppa is generally up to date.
Now, it looks like the easiest way is to download the new packaged version (.deb or .rpm) from the official releases and install it over your previous one: https://github.com/atom/atom/releases
It's now even easier with the APT package.
sudo add-apt-repository ppa:webupd8team/atom
sudo apt update
sudo apt install atom
And now you can upgrade / dist-upgrade as usual
sudo apt upgrade
Current official documentation seem to recommend another method:
Atom Github Page
Debian Linux (Ubuntu)
Atom is only available for 64-bit Linux systems.
Download atom-amd64.deb from the Atom releases page.
Run sudo dpkg --install atom-amd64.deb on the downloaded package.
Launch Atom using the installed atom command.
The Linux version does not currently
automatically update so you will need to repeat these steps to upgrade
to future releases.
Red Hat Linux (Fedora 21 and under, CentOS, Red Hat)
Atom is only available for 64-bit Linux systems.
Download atom.x86_64.rpm from the Atom releases page.
Run sudo yum localinstall atom.x86_64.rpm on the downloaded package.
Launch Atom using the installed atom command.
The Linux version does not currently
automatically update so you will need to repeat these steps to upgrade
to future releases.
Fedora 22+
Atom is only available for 64-bit Linux systems.
Download atom.x86_64.rpm from the Atom releases page.
Run sudo dnf install ./atom.x86_64.rpm on the downloaded package.
Launch Atom using the installed atom command.
The Linux version does not currently
automatically update so you will need to repeat these steps to upgrade
to future releases.
As of this writing, the best option to upgrade to the latest released version of Atom is to check out the most recent tag and build it, especially if you built it in the first place.
cd atom
git pull
git checkout v0.115.0 (or whatever the latest release is: https://github.com/atom/atom/releases)
script/build
sudo script/grunt install
wget https://atom.io/download/deb -O atom64.deb
sudo dpkg --install atom64.deb
or
wget https://atom.io/download/rpm -O atom64.rpm
sudo dnf install atom64.rpm
the above URLs redirect to https://atom-installer.github.com/
An easier way is to install the atom-updater-linux from the packages on the atom website.
Go to edit > preferences > install and search for atom-updater-linux
or from the terminal:
apm install atom-updater-linux
This should check for updates after every launch and prompt you to install new updates.
Currently the preferred procedure is described at the atom pages Installing Atom - Platform-linux
When using the add-apt-repository suggested in the top answer, this URL is suggested.
The apt repository mentioned at the Atom pages:
curl -sL https://packagecloud.io/AtomEditor/atom/gpgkey | sudo apt-key add -
sudo sh -c 'echo "deb [arch=amd64] https://packagecloud.io/AtomEditor/atom/any/ any main" > /etc/apt/sources.list.d/atom.list'
sudo apt-get update
If you are onn Ubuntu you can go to the Ubuntu Software Center, search for Atom and just click on Update. Then job done!
If anybody is interested, I wrote a small atom package for this purpose.
The package is meant to timely inform the user of new versions being available (stable or beta, configurable via settings) and uses GitHub API under the hood. It is platform independent, so it should work with any linux distro, but also with Windows or other systems.
It does not perform the upgrade automatically as I wrote it for my needs and I was not interested in such feature. I may add it in the future should strong interest for it manifest itself, though.
Feedback is welcome, best as tickets on github.
I upgraded from
Atom : 1.26.1
Electron: 1.7.11
Chrome : 58.0.3029.110
Node : 7.9.0
to
Atom : 1.40.1
Electron: 3.1.10
Chrome : 66.0.3359.181
Node : 10.2.0
I followed these simple steps,
create a file
sudo nano /usr/local/bin/atom-update
copy following snippet and save with Ctrl+o and "enter" and Ctrl+x
your code
#!/bin/bash
wget -q https://github.com/atom/atom/releases/latest -O /tmp/latest
wget --progress=bar -q 'https://github.com'$(cat /tmp/latest | grep -o -E 'href="([^"#]+)atom-amd64.deb"' | cut -d'"' -f2 | sort | uniq) -O /tmp/atom-amd64.deb -q --show-progress
dpkg -i /tmp/atom-amd64.deb
Make it executable
sudo chmod +x /usr/local/bin/atom-update
Run the script to upgrade atom
sudo atom-update
Ubuntu 16.04 and later
Run these commands to quickly and easily install and upgrade the Atom text editor snap package from the terminal in Ubuntu 16.04 and later (64-bit only).
Install Atom text editor:
sudo snap install --classic atom
Note that a snap in classic confinement behaves as a traditionally packaged application with full access to the system, and Atom extension packages are installed into the user's home directory.
Upgrade Atom text editor:
sudo snap refresh --classic atom
I would add that you should probably clean before updating the build to prevent some nasty errors.
cd atom
git pull
script/clean
script/build
sudo script/grunt install
For debian I have created a bash script which does the following:
Check with https://api.github.com and dpkg if atom is installed and/or up-to date.
Download and install the atom.deb from github if needed.
Provide a --beta switch if somebody wants to maintain the beta version as well.
Fell free to use it, it is located here: https://gist.github.com/rumpelsepp/8a953d6c092cbeb043695cfada114bef
Since December 2017 Atom provides official repositories for all major Linux distributions. You can find the latest installation instructions here.
Latest Way is to first install $ apm install atom-updater-linux then simply press Alt+Ctrl+U or go to Help and there is option for check for updates
I'm a newbie in OpenCL.
From yesterday, I'm trying to use OpenCL for parallel programming instead of CUDA which is more familiar for me and experienced before.
Now I have NVIDIA GTX 580 GPU, Ubuntu Linux 12.04 OS and CUDA SDK 4.1 (already installed before because of CUDA programming).
In CUDA SDK folder, Some OpenCL header file and library are already included.
So I just downloaded OpenCL examples from NVIDIA's Developer zone.
(Here is the link! https://developer.nvidia.com/opencl)
And I'm tried to compile some example by myself, but I couldn't.
I make Makefile by using -I I added path of header file, but I don't know how to added library path and what is the name of OpenCL library.
I searched on Google but someone said file named libOpenCL.so, but I only have OpenCL.lib.
Is Someone can help me?
Install
The following steps have been tested on Ubuntu 12.04.
Download the Intel SDK for Linux.
Extract the RPM:
$ tar zxvf intel_sdk_for_ocl_applications_2012_x64.tgz
Convert to .deb and install:
$ fakeroot alien --to-deb intel_ocl_sdk_2012_x64.rpm
$ sudo dpkg -i intel-ocl-sdk_2.0-31361_amd64.deb
Ensure that libOpenCL.so has been installed to /usr/lib/.
$ sudo ln -s /usr/lib64/libOpenCL.so /usr/lib/libOpenCL.so
$ sudo ldconfig
Compile
Simply link to the OpenCL library during compilation:
$ g++ main.cpp -lOpenCL
$ ./a.out
I am trying to run glassfish updatetool my in Ubuntu 12.04 x64. When I run the program it gives me following error.
---------------------------------------------------------------
There was an error running
/home/mrmrumman/glassfish3/updatetool/bin/../../pkg/python2.4-minimal/bin/python
You are running on a 64 bit Linux distribution and the 32 bit Linux
compatibility libraries do not appear to be installed. In order to use
the Update Center tools you must install the 32 bit compatibility libraries.
On Ubuntu (and possibly other Debian based systems) please install the
ia32-libs package. On RedHat 4 (and other RPM based systems), you may
need to add multiple 'compat' runtime library packages. Please see the
Update Center Release Notes for more information
I already install this package still it doesn't work. What can I do?
You also need to install 32 bit version of libjpeg.so.62 .
You can do so by running this command
sudo apt-get install libjpeg62:i386
Source : https://java.net/projects/updatecenter/lists/dev/archive/2012-05/message/0
For glassfish4 on ubuntu 12.04 x64 make sure you have the recommended updates for precise ticked in Settings of Update Manager, then
sudo apt-get install ia32-libs
This is not quite enough though because the pkg command looks for those libs in the wrong directories for the ubuntu installation. Help it find them with this command
sudo ln -s /lib/i386-linux-gnu /usr/lib32
Then the pkg command should work fine.
