I am trying to make something really simple. A simple hello world program that's installable as a package for arch. So i've tried to create a PKGBUILD file but i couldnt figure it out on how to package it. What i want to accomplish is:
Grab my repo from github
Compile the file/-s
Create a system variable so that i can run it from anywhere with a predefinded keyword
(optional) checking with gpg
And i want to generate a package that i can install using sudo pacman -U helloworld-1.10.tar.xz
I hope someone could help. Any help would be very good to have. Thanks :-)

I am a beginner in Python, trying to still learn the basics. I am mostly interested in using it for Data Analysis and Visualizations, with packages such as matplotlib.
Most of the examples I see, use the code
"import matplotlib"
or something similar.
But there are also cases when people suggest using pip install the use the package.
So, as a rule of thumb, when should one use import and when should one install through the terminal?
Let's say you want to use some library. Let its name be ABC. ABC has some function, let's say function1.
If you write
import ABC
ABC.function1()
you will get error. Because in your virtual environment python can't find library called ABC. You must install it first using pip install ABC in your terminal. After that same code will work.
You must install library first in order to use it.
There is no thumb rule for using a method to install. You can use any method for installing. Aim is to install so that the library is available when you run the code, else you will get an error.
In Windows, if you want to install a package/library use the following Command on DOS Prompt
python3 -m pip install matplotlib.
To Upgrade the same, use the following Command on DOS Prompt
python3 -m pip install --upgrade matplotlib.
You can install and upgrade the package/libraries through Jupyter too.
Once installed, you need to place the import <library_name> on top of the code in which you want to use that library.
I am a programming starter to try github for the first time.

I completed the clone as described in the main link.
I have also completed the npm installation as described in the text and have successfully run it.
But if i simply want to use source code, do i not need to install the module using npm?
Why do I install the module using npm?..
How do I use the packages I installed using npm?
Even if I did a search on Google, there was no post for beginners like me.
I really appreciate your advice.
I am currently working to develop a code which helps me to find a closest string match for a given string from a list of strings. I came across a Perl module Text::Fuzzy which helps me to do that. But i am working on cygwin and a having hard time installing it properly by using cpan commands. So how do i properly install it?
Can't exec "make": No such file or directory at /usr/lib/perl5/5.22/CPAN/Distribution.pm
This means that make is missing. You will have to install make to be able to install a Perl module.
Just do
apt-get install build-essential
Edit: Since you are using cygwin, please refer the link which xxfelixxx has suggested.
I have a hard time understanding where is the right place to place a code that will install the needed packages for the given docker container managed by dokku.
We have a scala application and, unfortunately, we need to have one shell call that is dependent on an environment. I would like to install the given package for the given container using "apt-get install". Right now I am using a custom plugin with a file named "post-release-build". However, I don't have the permission to install anything in that phase.
Basically, my script that should be invoked looks like this (based on a dockerfile that is available online):
apt-get update
apt-get install -y build-essential xorg libssl-dev libxrender-dev wget gdebi
wget http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-trusty-amd64.deb
gdebi --n wkhtmltox-0.12.2.1_linux-trusty-amd64.deb
echo "-----> wkhtmltox installed!"
Is there a way how to make it work? I would also prefer to have such a file somewhere in the application so I don't need to setup environment before pushing the app (in the future).
EDIT:
I have found a plugin that should be capable of installing packages using apt-get (https://github.com/F4-Group/dokku-apt) however, I am a little bit unlucky because it downloads a package that is not working properly.
Since just downloading with apt-get will download a package that fails, I investigated deeper into dokku and came out with a new plugin that should install the package for you.
I have created a script, documented how to use it and licenced it over MIT license so feel free to use it. Hopefully it will save you the time I had to spend realizing what is going on.

I am using Ubuntu 12.04. I have installed doxygen 1.8.3.1 using make install.
I would like to uninstall the doxygen built by make, but I don't find any way to do it using make (uninstall or clean...).
In the Makefile there is no reference to uninstall it the software. :(
Unfortunately I can't use the sudo apt-get remove doxygen because it wasn't an installed. :(
I don't find anything related on the internet.
Can anyone help me, please?
Thank you in advance,
Fabiola
There is no "uninstall" target. You need to do a "rm" be hand. If you used the standard prefix path "/usr/local" then
rm /usr/local/bin/doxygen
rm /usr/local/man/man.1/doxygen.1
(more if you install the docs are wizard). Depend on the user used for install, you need sudo to do it.
I know this question is old, but since it is the first result in google I would like to share another way of uninstalling Doxygen built from source. In the build directory where you've ran make there should by a file name install_manifest.txt. That file contains paths to files that were installed using make install command. All you need to do is to run the following command:
sudo xargs rm < install_manifest.txt
Of course this assumes that you've kept the build directory or at least the install_manifest.txt file. If not you need to remove the files by hand as somebody already suggested.
