For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
GD - GD::Graph

Posted by cliffwea (cliffwea), 9 October 2003
Hi there

I am trying to setup a questionnaire, that ouputs results in graph format. I am using Perl, and hopefully some modules. What I need to know, is what level of access I need to a web server to run the modules?

Can I use shared web space, or do I need more, what question would I ask the hosting company to clarify the position

Also, would some one like be suitable

Thanks for your help on this issue.

The GD module includes C code, and to compile and install these you'll need web space on which you can run the compiler; it should be possible for you to install them in your own area so that (technically) you don't need a dedicated server / root access etc.    Beware - there are very few ISPs out there  who will give you sufficient flexibiity, but I think you *should* get it at Hurricane.   I was certainly compiling up C code there the other day and it works fine, but I've not tried GD.

At the risk of you saying "oh no - not another language", I can be certain that Hurricane support dynamic graphics under PHP; we use it ourseleves.   There's nothing (but the technology mix that you might not be familiar with) to stop your Perl application generating HTML as per normal, and the images it generates being references to PHP scripts that actually make up JPEGs on thge fly.   I could do you a demo of this in an hour or two if you happen to be our way
