I'm trying to install Tmux under a Cygwin 64-bit installation on Windows 7 64-bit. I'm following these instructions: http://java.ociweb.com/mark/programming/tmuxInCygwin.html

I successfully compiled and installed libevent and ncurses, but I get this error when I try to make the patched version of tmux:

Is there any way I can work around that error?

Alternatively, is there another way to get Tmux working on Cygwin?

Is there any particular reason you need to use tmux instead of screen? screen is in the repository and works out of the box. – nitro2k01 Feb 7 '14 at 8:43
    
Yes, I know. I need to use tmux because it's required for the Vim-R-Plugin to work – enricoferrero Feb 7 '14 at 8:46

This may be of interest to you: tmux has been released as a cygwin package just recently!

Please have a look at the announcement at on the Cygwin-Announce mailing list; you can now simply install tmux with the common cygwin setup-{x86|x64}.exe.

I just had exactly the same issue.

I solved it by editing tty-term.c. Search for 'cur_term' and comment out the line.

It compiled fine after that. Not sure if there are any downsides to this. Haven't seen any yet!
