I was watching this, and, as you can see, the first command I am told to put in is:
sudo apt-get install python-setuptools
When I do this, it outputs:
sudo: apt-get: command not found
I have no idea why this is the case.
How can I resolve this so I am following the tutorial correctly?
Mac OS X doesn't have apt-get. There is a package manager called Homebrew that is used instead.
This command would be:
brew install python
Use Homebrew to install packages that you would otherwise use apt-get for.
The page I linked to has an up-to-date way of installing homebrew, but at present, you can install Homebrew as follows:
Type the following in your Mac OS X terminal:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
After that, usage of Homebrew is brew install <package>.
One of the prerequisites for Homebrew are the XCode command line tools.
Install XCode from the App Store.
Follow the directions in this Stack Overflow answer to install the XCode Command Line Tools.
Background
A package manager (like apt-get or brew) just gives your system an easy and automated way to install packages or libraries. Different systems use different programs. apt and its derivatives are used on Debian based linux systems. Red Hat-ish Linux systems use rpm (or at least they did many, many, years ago). yum is also a package manager for RedHat based systems.
Alpine based systems use apk.
Warning
As of 25 April 2016, homebrew opts the user in to sending analytics by default. This can be opted out of in two ways:
Setting an environment variable:
Open your favorite environment variable editor.
Set the following: HOMEBREW_NO_ANALYTICS=1 in whereever you keep your environment variables (typically something like ~/.bash_profile)
Close the file, and either restart the terminal or source ~/.bash_profile.
Running the following command:
brew analytics off
the analytics status can then be checked with the command:
brew analytics
As Homebrew is my favorite for macOS although it is possible to have apt-get on macOS using Fink.
MacPorts is another package manager for OS X:.
Installation instructions are at The MacPorts Project -- Download & Installation after which one issues sudo port install pythonXX, where XX is 27 or 35.
Conda can also be used as package manager. It can be installed from Anaconda.
Alternatively, a free minimal installer is Miniconda.
apt-get command is only available on Debian or Debian-based Linux distributions (such as Ubuntu, Linux Mint, Kali). It is not accessible on macOS. Alternatively, you can use package managers like Homebrew, MacPorts, and Nix. You can find equivalent commands for each as follows
brew install package_name
sudo port install package_name
nix-env -i package_name
Before installing above package managers, you need to install XCode first. Follow the operation instructions from this guide How to Fix "sudo apt-get command not found" Error on Mac Terminal.
Alternatively You can use the brew or curl command for installing things, wherever apt-get is mentioned with a URL...
For example,
curl -O http://www.magentocommerce.com/downloads/assets/1.8.1.0/magento-1.8.1.0.tar.gz
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
I am new to aerospike and just getting used to it. Now I have installed the C client library as they have described in their documentation.
Here is my code
Test.c
And this is the error that I get on compiling it.
Error
I am assuming here that the linker is somehow not able to connect the function of the aerospike client to my code. I am not able to understand how to solve it!
Here are my notes from using C Client inside an Ubuntu VM, Aerospike server is also installed inside this VM and running.
Using eclipse to develp C code:
sudo apt-get install eclipse eclipse-cdt g++
Note: C Client does not support AsuRM processors.
I am working inside a Ubuntu 16.04 VM.
$lsb_release -a ⇒ shows my ubuntu version
pgupta#ubuntu:/var/log/aerospike$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.1 LTS
Release: 16.04
Codename: xenial
Required library:
$cd ~
$sudo apt-get install libssl-dev
Download C Client and install for Ubuntu 16.x: http://www.aerospike.com/docs/client/c/install
It was downloaded in my ~/Downloads directory.
$cd Downloads/
$ls
$tar xvf aerospike-client-c-4.1.1.ubuntu16.04.x86_64.tgz
$cd aerospike-client-c-4.1.1.ubuntu16.04.x86_64/
$ sudo dpkg -i aerospike-client-c-devel-4.1.1.ubuntu16.04.x86_64.deb
$ cd examples
$ make
$cd basic_examples/
$cd put
$cd target/
$ sudo service aerospike start (I have a server running in my ubuntu 16 VM)
$./example
Output shows I was able to read and write records to the server.
I need to install libssl1.0.0 on a ubuntu 10.04 machine offline.
After lots of search, I still cannot find any libssl1.0.0 packages built for ubuntu 10.04. Building it from source is not accepted, because it takes several minutes to complete the build and installation process while I only have few seconds to finish the job.
Please advise me how to quickly install libssl1.0.0 on ubuntu 10.04 offline.
Finally I use checkinstall to build debian package from last version of source. If checkinstall does not exist in the system, it can be installed by apt-get install checkinstall. The rest of steps are:
tar xf openssl-1.0.1e.tar.gz
cd openssl-1.0.1e
./config --prefix=/usr shared
make
checkinstall
Then openssl_1.0.1e-1_amd64.deb will be available under openssl-1.0.1e folder.
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.
