gVim

If you use gVim, you can get copy-on-select behaviour when using :set guioptions+=a.
This is enabled by default on X11 systems (copies to PRIMARY), but not on MS Windows & OSX (as selecting any text would override your clipboard).

No +clipboard?

Vim requires the +clipboard feature flag for any of this to work; you can check if your Vim has this by using :echo has('clipboard') from within Vim (if the output is 0, it not present, if it's 1, it is), or checking the output of vim --version.

Most Linux distributions ship with a "minimal" Vim build by default, which doesn't have +clipboard, but you can usually install it:

• Debian & Ubuntu: Install vim-gtk or vim-gnome.

• Fedora: install vim-X11, and run vimx instead of vim (more info).

• Arch Linux: install gvim (this will enable +clipboard for normal vim as well).

You could also use xclip, xcopy, or xsel to copy text to the clipboard; see the following questions for solutions:
