Linux
Several years ago I started exploring Linux. But in the
summer of 1999 I actually started using
Linux.
As you can see on my other pages I am interested in
programming in Delphi. For that reason I wanted to start
programming in Linux. As a teacher I know that most
people prefer a graphical shell, so when you intend to
write educational programs you must do that for
(X)windows.
First I had to learn the C-language as it is THE language
for Linux. Then I had to look for a suitable programming
environment. I discoverd on one of my Linux CD's the
package Xforms. After some problems installing the
package I finaly got it working.
Most distributions
contain a package containing the xforms library. When you have
this package installed you must be able to run the binary
included in the packages I wrote. Most distributions have
version 0.89 of the Xforms library included so I
compiled my programs with that library.
There is a newer versions of the Xforms library, so I recommend to take a look at the XForms homesite :
http://savannah.nongnu.org/projects/xforms/
Because I didn't understand what to do with the Makefiles (most of my programs are short and contain only one file, so
a makefile isn't really necessairy) I wrote a simple program called "comp". With
this program I could compile my xforms programs in a very easy way .
F.i. to compile the program 'lucas.c' (see below) I only
had to enter : comp lucas.
I think Linux is a great platform for educational
purposes (pupils know very well how to bypass security
measurements in Windows95/98). So I started programming
to convert some programs written in Delphi to Xforms.
Today xforms aren't very popular anymore. Take a look at the sourcecode to get some ideas for programming if you like.
If you want to do graphical programming on the Linux platform, please take e look at my Lazarus page.
When you are programming educational software for Linux I
would like to hear about that, so maybe we can join our
efforts.
At this moment I have available.
