Python Cgi Script Not Working, Help Please

[johnchoo]

Hi everybody,

 

I am quite excited to be starting my first website with heliohost, and am happy to join this community.

 

My first challenge: I have a python cgi script, that calls a module, the files for which are placed in the same folder as the python cgi script. the folder is placed as a sub folder under the cgi-bin folder. I have placed the python shebang line(#!/usr/bin/python), the content type (print("Content-type: image/png\n")), and made the entire subfolder and its contents chmod permission 755.

 

the code in my file is as follows:

#!/usr/bin/python

from pychartdir import *

 

# The data for the bar chart

data = [85, 156, 179.5, 211, 123]

 

# The labels for the bar chart

labels = ["Mon", "Tue", "Wed", "Thu", "Fri"]

 

# Create a XYChart object of size 250 x 250 pixels

c = XYChart(250, 250)

 

# Set the plotarea at (30, 20) and of size 200 x 200 pixels

c.setPlotArea(30, 20, 200, 200)

 

# Add a bar chart layer using the given data

c.addBarLayer(data)

 

# Set the labels on the x axis.

c.xAxis().setLabels(labels)

 

# Output the chart

print("Content-type: image/png\n")

binaryPrint(c.makeChart2(PNG))

 

I placed all the files for the pychartdir module in the same folder.

but it still doesnt work. the link is here: http://promtech.heliohost.org/ . (its the 3rd broken link)

 

I would appreciate very much if anyone here can point out something I have been missing. I have tried to find the answers on these forums and google, but have come up with nothing that works. Many thanks in advance!

I was able to generate this thing here - http://yash.heliohost.org/cgi-bin/ChartDirector/lib/yash.py

 

I guess you are using the Linux (i386/i686) platform. Use the Linux (x86_64) platform from here: http://download2.advsofteng.com/chartdir_python_linux_64.tar.gz

Hi Yashrs,

 

That is fantastic! how did you do it? Yes I was using the (i386/i686) version, and it was because my laptop is 32 bit. Why is it that the 64 bit version works? is it because the server is 64 bit linux? I am sorry for my noob question, but I am new at this, and would really love to learn how to make it work.

I am assuming there is nothing wrong with the python script? so therefore the problem is in some settings? I am afraid I still can't get mine to work.

I guess you have this in the second last line :-

print("Content-type: image/png\n\n")

It should be

print("Content-type: image/png\n")

Try it and see if that works out !

[johnchoo]

YESSS!! IT works!!!

 

Thank you Mr Yashrs, you are a life saver.

 

btw, is the server really 64bit?

[yashrs]

The architecture is x86_64.

[johnchoo]

Thank you for the reply.

You are welcome. Glad your problem got solved.
