tmux: Depends on ncurses

[jaens]

Looks like it is unable to find the system curses:

There's a system ncurses-devel package installed, version 5.7.

After installing homebrew/dupes/ncurses, the install succeeds.
I do not see ncurses mentioned as a system requirement for linuxbrew, why is it in dupes and not a dependency of tmux?

[tseemann]

I can build it on RHEL 7 but I think you are correct in that it has a missing ncurses dependency.

% ldd /bio/linuxbrew/bin/tmux
        libncursesw.so.6 => /bio/linuxbrew/lib/libncursesw.so.6 (0x00007fe53b0d6000)

I do have homebrew/dupes/ncurses installed.

If you have the RPMs for ncurses-libs and ncurses-devel it might use those too.

I think ncurses is one of those packages that is guaranteed to come with OSX but needs special rule for Linux, like zsh does:

depends_on "homebrew/dupes/ncurses" unless OS.mac?

[sjackman]

I've added the dependency and built a bottle for Linuxbrew.

brew update
brew install tmux

should work now.
