installing qt4-make on ubuntu 12.04 LTS - c

I am running ubuntu 12.0.4 LTS on my controller. I was trying to install qt4-make using apt-get, but I am getting a message that the package is not found. I need this to make and compile a file. How can I install this ? Also, is there any alternative I can download ? I even tried sudo apt-get install libqt4-* . Still nothing happens.

I think qt4-make is qmake, so try this:
sudo apt-get install qt4-qmake

Install OpenMPI on Ubuntu 17.10

I am using the following command for OpenMPI installation on Ubuntu 17.10:
sudo apt-get install openmpi-bin openmpi-common openssh-client openssh-server libopenmpi1.3 libopenmpi-dbg libopenmpi-dev.
However, I get the following error:
E: Unable to locate package libopenmpi1.3
I wanted to know how to fix this. Alternatively,I am open to installing openmpi differently if anyone knows another way of doing it.
apt-get install libopenmpi1.10 would work.

Install arm-poky-linux-gnueabi toolchain on PC

There are 2 compilers used in IMX7(ARM Yocto Linux):
arm-poky-linux-gnueabi-gcc
arm-poky-linux-gnueabi-g++
When I build complete image by spending about 2 hours its already downloaded.
But I would like to know how to install this tool chain directly on PC(Ubuntu/CentOS) and use it as separate compiler in PC instead of with its Image as I mentioned above.
Use below command in your ubuntu pc
$ sudo apt-get install gcc-arm-linux-gnueabihf
$ sudo apt-get install g++-arm-linux-gnueabihf

Try to compile, install and run imgmin on ubuntu server, but command not found

I try to use imgmin (written in C) by rflynn (see on GitHub rflynn/imgmin).
So I followed the instructions
sudo apt-get install -y autoconf libmagickwand-dev pngnq pngcrush pngquant
git clone https://github.com/rflynn/imgmin.git
cd imgmin
autoreconf -fi
./configure
make
sudo make install
imgmin original.jpg optimized.jpg
I compiled and installed it without any problems (or notices). But I can't run "imgmin", it always tells me:
-bash: imgmin: command not found
Where is my mistake? Thank you for any suggestion.
I'm running on Ubuntu Server 16.04 LTS with latest updates.

Error while installing CodeLite IDE in Ubuntu

While installing CodeLite IDE in Ubuntu following error occurs.
Any idea?
ERROR:
The following packages have unmet dependencies:
codelite : Depends: libjbig0 but it is not installable
Depends: liblzma5 (>= 5.1.1alpha+20120614) but 5.1.1alpha+20110809-3 is to be installed

E: Unable to correct problems, you have held broken packages.
I had a similar problem. You may need to check your version of Ubuntu, and that you've added the correct repositories. If this is the problem, then the fix is very simple!
Firstly, check your version of Ubuntu. From terminal you can do this with the command lsb_release -a. The important part, for our purpose, is the codename. I'm using Ubuntu 13, aka "saucy".
Now let's look at the multiverse repository that you added. From the terminal you can do this with sudo gedit /etc/apt/sources.list. Go down to the end of the file, and you should see something like:
## This software is not part of Ubuntu, but is offered by third-party
## developers who want to ship their latest software.
deb http://repos.codelite.org/ubuntu/ saucy universe
Make sure that your version has your ubuntu codename (in my case 'saucy'). The example code on the website is for Ubuntu 14, and so I wrongly had a 'trusty' source here. Edit the line so that it is correct for your version of Ubuntu, and then save and close the file.
Lastly, you'll need to update your repos so that the change goes through. From the terminal, run sudo apt-get update. All being well, you should now be able to sudo apt-get install codelite without the errors.
My problem was caused by too much cutting-and-pasting code from the codelite website. I followed exactly the same page as you did, and their example code is for people with Ubuntu trusy (14).
You will need to be more specific on how you tried to install codelite.
The official Debian repository manages an ancient version of codelite which we (the codelite team) do not support.
In order to get the most up-to-date version (that we support) please install it from codelite's official website (select the Download at menu at the top)
Before installing, make sure you delete the folder ~/.codelite (incase you are upgrading)
Also, the official Debian installer is split into 2 pakacges codelite and codelite-plugins make sure you purge them both before installing codelite from our repository
I'm the author of Howto install the latest codelite in Ubuntu - EuroBytes. I have tested the latest codelite on Trusty.
If you still have issues with codelite, remove like so: sudo apt-get purge codelite
Note that the dependencies links are dead. But, i managed to install it anyways:
codelite 6.1 on Ubuntu Trusty Thar 14.04.
Image from: Howto install the latest codelite in Ubuntu - EuroBytes
Install like so:
sudo apt-add-repository "deb http://repos.codelite.org/ubuntu/ $(lsb_release -sc) universe"
sudo apt-key adv --fetch-keys http://repos.codelite.org/CodeLite.asc
sudo apt-get update
sudo apt-get install codelite wxcrafter
Feel free to contact me here or on my site, for any issues you may have.

opencv install folder on ubuntu

I installed opencv2.3 on ubuntu by first adding the ppa and the doing apt-get install
$ sudo add-apt-repository ppa:gijzelaar/cuda
$ sudo add-apt-repository ppa:gijzelaar/opencv2.3
$ sudo apt-get update
$ sudo apt-get install libopencv-dev
I am developing on Eclipse and my programs work. I have this one problem though, while following an ebook. I cannot find the /opencv/samples folder in my system. I did a unix directory search to no avail.
Also, in Synaptic Package Manager I find that the opencv packages are not marked green, ie they're not installed. However I have written and executed opencv codes on my machine.
What is the reason for this?
It seems you have installed binary OpenCV package while the samples are (most likely) included only to source package.
