To install additional packages for Cygwin, do I just need to run the setup.exe again and choose from the packages list?
Also, doing this won't harm my computer in terms of 2 Cygwin instances being installed or problems of that kind (I'm kind of a noobie with these things).
Last, there is no package manager in Cygwin which you can run in the command line? Something similar to Pip in Python.
No, adding additional packages doesn’t modify the current settings. There is a
package manager called apt-cyg which installes additional packages from
command-line. To install apt-cyg follow the below steps:
wget rawgit.com/transcode-open/apt-cyg/master/apt-cyg
install apt-cyg /bin
Note: wget should be installed for downloading the apt-cyg. To Use apt-cyg for
installing additional package (after following the above steps):
apt-cyg install ncurses
No, it doesn't hurt the current setup. The install program knows what's installed already.
Having said that, I long ago got into the habit of installing all of Cygwin since, despite its size, it's still minuscule compared to the size of modern hard disks. That way, you won't ever have to worry about whether a package is installed or not.
Re-run the setup executable like "cygwin_setup-x86_64.exe" should do it.
"Install from Internet"
Accept your existing root directory (from your existing installation)
Use your existing "Local Package Directory"
On the screen, view "Full"
Search for the new package you want to add
Go through the installation
Additional option, may be helpful for someone:
To install additional packages in windows from windows command line you can use your cygwin installer.
I suppose, you've already downloaded it to install cygwin from here https://cygwin.com/install.html.
$ setup-x86_64.exe -q -P graphviz
see this guide for details:
http://preshing.com/20141108/how-to-install-the-latest-gcc-on-windows/
There is no package management in Cygwin outside of the setup program. The setup only applies updates to your current installation, it does not overwrite packages than what you already have.
So if you want new packages just rerun the setup program to install packages.
You can just look for the package binaries and decompress them in the C:\cygwin\bin folder.
I did that for dos2unix ( https://cygwin.com/packages/summary/dos2unix.html ) and trying it out now.

I have a system setup of Haskell that I've maintained with Homebrew and subsequent cabal install invocations for various packages. I would like to take this back to the bare installation created with brew install haskell-stack.
How do I do this? Right now I seem to have a bunch of stuff lying around (e.g. old docsets, executables like ghc-mod etc.) at the system level, even after deleting all installed packages with rm -r ~/.ghc. Is there a reliable way to get back to the basic configuration that brew install haskell-stack creates?
Is it possible to use RPM or YUM or any other package manager in Linux, specifically CentOS, to install a package either already downloaded or from repo to a custom location without admin/root access?
I tried building from sources, using cmake, configure, make, make install etc, but, it ended up having so many dependencies one after other.
Or are there any better alternatives?
It is possible to use yum and rpm to install any package in the repository of the distribution. Here is the recipe:
Find the package name
Use yum search.
Download
Download the package and all of its dependencies using yumdownloader (which is available on CentOS by default). You'll need to pass it --resolve to get dependency resolution. yumdownloader downloads to the current directory unless you specify a --destdir.
mkdir -p ~/rpm
yumdownloader --destdir ~/rpm --resolve vim-common
Choose a prefix location
It might be ~, ~/centos, or ~/y. If your home is slow because it is on a network file system, you can put it in /var/tmp/....
mkdir ~/centos
Extract all .rpm packages
Extract all .rpm packages to your chosen prefix location.
cd ~/centos && rpm2cpio ~/rpm/x.rpm | cpio -id
rpm2cpio outputs the .rpm file as a .cpio archive on stdout.
cpio reads it from from stdin
-i means extract (to the current directory)
-d means create missing directory
You can optionally use -v: verbose
Configure the environment
You will need to configure the environment variable PATH and LD_LIBRARY_PATH for the installed packages to work correctly. Here is the corresponding sample from my ~/.bashrc:
export PATH="$HOME/centos/usr/sbin:$HOME/centos/usr/bin:$HOME/centos/bin:$PATH"
export MANPATH="$HOME/centos/usr/share/man:$MANPATH"
L='/lib:/lib64:/usr/lib:/usr/lib64'
export LD_LIBRARY_PATH="$HOME/centos/usr/lib:$HOME/centos/usr/lib64:$L"
Edited note (thanks to #AmitNaidu for pointing out my mistake):
According to bash documentation about startup files, when connecting to a server via ssh, only .bashrc is sourced:
Invoked by remote shell daemon
Bash attempts to determine when it is being run with its standard input connected to a network connection, as when executed by the remote shell daemon, usually rshd, or the secure shell daemon sshd. If Bash determines it is being run in this fashion, it reads and executes commands from ~/.bashrc, if that file exists and is readable.
Now if you want to install a lot of packages that way, you might want to automate the process. If so, have a look at this repository.
Extra note: if you are trying to install any of gcc, zlib, make, cmake, git, fish, zsh or tmux , you should really consider using conda, see my other answer.
TL;DR Use Miniconda, conda-forge is amazing.
curl "https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh" | sh
Or, alternatively:
curl https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh > Miniconda.sh
bash Miniconda.sh -b -p ~/conda
# -b is used to specify that this is done "in batch", so skip the EULA prompt
# -p lets you specify where you want conda installed
Commonly wanted packages:
gcc conda install gcc
zlib conda install zlib
make conda install make
cmake conda install cmake
git conda install git
fish conda install -c conda-forge fish
zsh conda install -c ActivisionGameScience zsh
tmux conda install -c conda-forge tmux
This tmux has a bug with the name of the ncurse library it uses. You can work around it by going to your da/lib folder and symlinking ln -sT libtinfow.so.6.1 libtinfo.so.6
For the rest, you can try https://anaconda.org/search?q=.
I've tried for a long time to get a package manager to work well on CentOS/RedHat but without success. The best I could do was to install a Gentoo Prefix at the correct location on another CentOS with root access, then scp a .tar.xz of the whole installation to the target server (only way to get a proper gcc for Gentoo Prefix). I could emerge (build & install) packages on the target server but kept hitting problems with locals and permissions.
I recently achieved a user installation of some interesting packages using conda. Here is how to install it from the command line:
curl "https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh" | sh
If like me, your home folder is hosted on a remote drive (a network file system), you might not want to install it in your home folder, so you might want to use something like mkdir /var/tmp/lo then specify an installation folder like /var/tmp/lo/da during the installation.
You'll then be able to install quite a lot of packages, though maybe not all those you wanted. Most of the time, if it is not in the default channel, it will be in conda-forge. You can check for existing packages at https://anaconda.org/search?q=
Other package managers I've tried to use after conda:
Linuxbrew
I thought that with that it would be easy to install homebrew (linuxbrew) but their sources are messy and use hard-coded absolute path to ruby interpreter, which fails because it isn't the last version and so on and so on and I gave up.
Nix
Nix still requires you to use the /nix folder. They hard-coded it too and it's hard to sed it correctly from every download it has to do during the installation (let alone updates).
Gentoo Prefix
I expect Gentoo Prefix to be easier to install directly now that we gcc can be used on the target server. -- Ok, I tried but met permissions bugs during installation (2018-09-28):
portage.exception.OperationNotPermitted: chown(b'~/gentoo/tmp/var/tmp/portage/sys-apps/gentoo-functions-0.12/image/var', 2000, 2000)
PkgSrc
I'm going to try pkgsrc now. -- Use (older) version 64-bit EL 6.x if on CentOS 6 or if encountering (G)LibC version issues with the 7.x one. -- No luck, pkgsrc hard codes /usr/pkg/sbin and /usr/pkg/bin. So it can't be used as user, unless maybe setting up a fakechroot environment. But I've never done that and I expect usability issues.
Please comment/answer if you succeed in installing any other package manager.
Download the packages, and indicate to include dependencies with the --resolve flag.
yumdownloader --resolve openslide-tools
Iterate over all downloaded rpm files.
for i in *.rpm; do rpm2cpio $i | cpio -idv; done
the output will be stored in your present working directory $PWD/usr/*
This answer by goldilocks sounds like what you are looking for.
https://unix.stackexchange.com/a/61295
It's still not a pretty process, but seems easier than building from source.
Otherwise you might want to look into non-root package managers as an alternative to yum.
Yes it is. If the software is packaged in repos. And admin installed
PackageKit-command-not-found package.

I was install a package by rpm command in redhat, but the package is failure now.
I want create a new package from installed package.
what can I do?
This command would help you in that,
rpm -Fvh –repackage rpm-file-name.rpm
Here rpm-file-name.rpm is an existing package in Linux which will be repackage by using above option.
From man page of rpm;
–repackage Re-package the files before erasing.
–replacefiles Install the packages even if they replace files from
other, already installed, packages.
–replacepkgs Install the packages even if some of them are already
installed on this system.
rpmrebuild is built for re-creating RPM package files from already installed packages. There are options which allow you to tailor the packaging, but the most simple invocation just produces an RPM file from an installed package. Example: rpmrebuild coreutils
Is there any apt-get-like program for use with Cygwin?
I already tried cyg-apt but when I try I get this error:
cyg-apt: downloading: http://cygwin.mirrors.pair.com/setup-2.bz2
cyg-apt: downloading: http://cygwin.mirrors.pair.com/setup-2.ini
cyg-apt: bad URL http://cygwin.mirrors.pair.com/setup-2.ini, exiting.
Best I have ever used:
apt-cyg package manager
You can do this using Cygwin’s setup.exe from Windows command line. Example:
cd C:\cygwin64
setup-x86_64 -q -P wget,tar,gawk,bzip2,subversion,vim
For a more convenient installer, you may want to use the
apt-cyg package manager. Its syntax is
similar to apt-get, which is a plus. For this, follow the above steps and then
use Cygwin Bash for the following steps:
wget rawgit.com/transcode-open/apt-cyg/master/apt-cyg
install apt-cyg /bin
Now that apt-cyg is installed. Here are a few examples of installing some
packages:
apt-cyg install nano
apt-cyg install git
apt-cyg install ca-certificates
Update: you can read the more complex answer, which contains more methods and information.
There exists a couple of scripts, which can be used as simple package managers. But as far as I know, none of them allows you to upgrade packages, because it’s not an easy task on Windows since there is not possible to overwrite files in use. So you have to close all Cygwin instances first and then you can use Cygwin’s native setup.exe (which itself does the upgrade via “replace after reboot” method, when files are in use).
apt-cyg
The best one for me. Simply because it’s one of the most recent. It works correctly for both platforms - x86 and x86_64. There exists a lot of forks with some additional features. For example the kou1okada fork is one of improved versions.
Cygwin’s setup.exe
It has also command line mode. Moreover it allows you to upgrade all installed packages at once.
setup.exe-x86_64.exe -q --packages=bash,vim
Example use:
setup.exe-x86_64.exe -q --packages="bash,vim"
You can create an alias for easier use, for example:
alias cyg-get="/cygdrive/d/path/to/cygwin/setup-x86_64.exe -q -P"
Then you can for example install the Vim package with:
cyg-get vim
you can always make a bash alias to setup*.exe files in $home/.bashrc
cygwin 32bit
alias cyg-get="/cygdrive/c/cygwin/setup-x86.exe -q -P"
cygwin 64bit
alias cyg-get="/cygdrive/c/cygwin64/setup-x86_64.exe -q -P"
now you can install packages with
cyg-get <package>
This got it working for me:
curl https://raw.githubusercontent.com/transcode-open/apt-cyg/master/apt-cyg > \
apt-cyg && install apt-cyg /bin
No. The only officially supported tool for downloading and updating Cygwin packages is the setup.exe file you used for the initial install, although that can be invoked with command line arguments to help the process.
From that same page:
The basic reason for not having a more full-featured package manager is that such a program would need full access to all of Cygwin's POSIX functionality. That is, however, difficult to provide in a Cygwin-free environment, such as exists on first installation. Additionally, Windows does not easily allow overwriting of in-use executables so installing a new version of the Cygwin DLL while a package manager is using the DLL is problematic.
You can use Chocolatey to install cyg-get and then install your packages with it.
For example:
choco install cyg-get
Then:
cyg-get install my-package
I am trying to build db-mysql extension for NodeJS under Cygwin. The problem is, that it requires libmysql development libraries and include files. I have no idea how to install (and where to get) this stuff to work with Cygwin. Under Ubuntu i would write something like this:
sudo apt-get install libmysqlclient-dev
But this is not possible under Cygwin. Also there is no available libmysql package when I run Cygwin's setup.exe. Does anybody know how to solve this isue?
I have installed wamp under Windows which includes MySQL database. I would like to use databases from that installation under Cygwin, is that possible?
Thanks
It's available from Cygwin Ports, a large repository of additional Cygwin packages that can be installed through Cygwin's setup.exe.
