Re: client on freebsd over tramp server on archlinux

[Shigio YAMAGUCHI]

OK. You are trying to use TRAMP function of emacs.

Can you invoke global command on the server side (freebsd) from the client side?
        $ ssh server global --version
Can you invoke 'global-client' script on the client site (archlinux)?
        $ which global-client

'global-client' should be here: /usr/local/share/gtags/script/global-client

If you can do these, please try again.

Regards,
Shigio
