This project allows offline Cygwin installation on Windows by pre-downloading it in advance on Linux (using Wine).

Features

• Ideal for those who wants to meet Windows only in virtual machines.

  • Download on Linux.
  • Deploy on Windows.

• Simple straightforward workflow.

  • Linux: packages.sh (optional)
  • Linux: update.sh
  • Linux: archive.sh (optional)
  • Windows: install.cmd

• No dependencies on software external to Windows during installation.

• Support for unattended (non-interactive) installation.

• Support only for 64 bit Linux/Windows versions.

Configure list of selected Cygwin packages

Modify list of packages for download:

packages.conf

The names of available packages to select from can be found in Packages column during selection of packages in Cygwin installer run with GUI. Script packages.sh starts Cygwin installer with GUI exactly for the purpose of reviewing available packages to list them in packages.conf:

packages.sh

NOTE: Script install.cmd will install list of packages specified before update.sh is run rather than consulting pakcages.conf again (the list used is cached in distrib/packages.line.conf file). See also comments in packages.conf.

Update Cygwin content from Internet on Linux

update.sh

This command will pre-download Cygwin content under distrib directory.

The command starts Cygwin setup in unattended mode (without GUI) and downloads all packages (with their dependencies) listed in packages.conf file.

It also automatically downloads official Cygwin installer placed in the following path relative to the root of this repository:

distrib/setup-x86_64.exe

WARNING: It is possible to install Cygwin on Linux on top of Wine. Do NOT do it. Make sure that the machine where updates are downloaded does not contain Cygwin installation. Otherwise the package may not be complete as Cygwin installer only downloads missing components. In its worst case, remove ~/.wine directory to get rid of any application installed on Wine.

Archive Cygwin content into single distributive file on Linux

archive.sh

This script will archive entire content of this directory with root of the archive matching root of this repository.

WARNING: If the downloaded content is incomplete, archive.sh script may (rightfully) fail as it inspects some files in the downloaded content. The downloaded content can be incomplete if Cygwin is installed on Wine - see warning in section for update.sh script.

Install Cygwin without Internet connectivity on Windows

install.cmd

This command will use pre-downloaded Cygwin content from distrib directory prepared by update.sh for offline installation.

The command is starts Cygwin setup in unattendant mode and installs everything (without GUI).

Run commands on Linux using Wine

When run on Linux, Wine is used.

Install Wine, for example on Fedora 24:

sudo dnf install -y wine

Pre-downloading packages via proxy

It is also possible to perform download via proxy server. Make sure to use right credentials for authentication (if required) - proxy setup may be selective about allowed content per user.

Unfortunately, there is no known way to provide username and password for proxy authentication to Cygwin installer. This makes it difficult to run update task automatically (e.g. in continuous integration platform) behind proxy with authentication.

Changelog

• v1.0.0

  • Make list of packages configurable in packages.conf file.

  • Fixed hang (due to command line switch into interactive mode) at the end of the installation if cmd /wait install.cmd is used.

  • Tag archived package using the following format:

    cygwin-offline.git-v[REPO_TAG]-[COMMITS_SINCE_TAG]-g[GIT_COMMIT_HASH]-[dirty].cygwin-v[CYGWIN_VERSION].zip
    

    For example:

    cygwin-offline.git-v0.0.0-11-g9127328-dirty.cygwin-v2.5.2.zip
    cygwin-offline.git-v0.0.0-11-g9127328.cygwin-v2.5.2.zip
    

  • Split unattended and interactive mode of Cygwin setup into packages.sh and update.sh scripts.

  • Clean up directories from obsolete and unsopported scripts.

• v0.0.0

  Initial version after spin-off.

  It worked for download-install cycle.

  It was tested on clean Windows 2012 R2 in windows-server-2012-R2-gui Vagrant box.
