requires python3, tkinter; AND cannot run headless about fio-plot

[louwrentius]

Thank you, X should not be required, I will try to reproduce and fix it. Which flavour of Linux do you run?

After installing the additional dependencies, it appears tkinter requires a working x display. :( I was so close! My thoughts: After the .json files are generated, send them to another machine with the additional libraries / dependencies for image generation.

This server is: CentOS Linux release 7.3.1611 (Core)

This is the temporary fix:

import os
import sys
import json
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
import numpy as np
import argparse

I ran this on Debian and it worked, but the fonts are screwed up. I'll look at that later. The tool is written on MacOS with brew.

spent lots of time on this problem, here is my solution effectively:

1. yum -y install tkinter tcl-devel tk-devel

to your python directory: vim ......./Python3.6.2/Modules/Setup.dist

2. Remove comments from these lines:

_tkinter _tkinter.c tkappinit.c -DWITH_APPINIT \

-L/usr/local/lib \

-I/usr/local/include \

-ltk8.5 -ltcl8.5 \ # default is 8.2 and you should change it to the version you installed in step1

-lX11

./configure
make && make install

I have released an almost total rewrite that requires python3. I've tested it on a clean Linux box and it seems to work fine, without the issues reported above.
