Installing xv on a Mac

I use John Bradley's program, xv, on a regular basis. It's a great Xwindows program for viewing, editing, and saving images. I recently installed it on a Mac.


Edit: Thursday September 20, 2018 -- I am transitioning to a new MacBook Air laptop, and went to download and install xv. I ran into some difficulty, and did an on-line search for help. When this page that I wrote popped up on the first page of search results, I knew I was in for some trouble! Fortunately, I found a solution that worked well: I downloaded MacPorts and installed it. From the command line, this is what I did next:

port version
sudo port selfupdate
port help
sudo port install xv
sudo port install XQuartz
sudo port install xfig

Legal note: I'm not officially endorsing these products, I'm not a developer of any of them, and I'm not making money off of them. Use them at your own discretion.



(Below is the continuation of my notes from 2009.)
I tried the "make" command after downloading the files, but had some problems. Below, I show how to correct these problems.

I had to modify several files to get "make" to work on this Mac. Below are the changes (I used the "diff" utility to show them).

Notes about using xv on a Mac:

Original Makefile:

Below is a script showing what I did to get xv to work on a Mac.
