Installing additional packages for Cygwin
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/
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
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.
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
