compiler for ELKS programs

compiler for ELKS programs

[jerryc]

Greetings,

Inspired by the feedback I have gotten from this list and my local LUG, 
I am learning to program C and use the curses / ncurses libraries. This 
seems like the best approach for putting Inner Peace on 8086's.

I read somewhere that ELKS itself does not have a compiler. If that's 
true, the code would have to be compiled on another computer, which 
should not be a problem. Some of what I'm reading refers to different 
coding styles for different compilers.

So, here are the relevant questions:

Does ELKS have a compiler?
If not, is there a compiler that will compile programs properly to run 
on ELKS?
If so, what kind of coding styles are needed?

Any other help and suggestions would be appreciated.

Thanks again for all your support for an ELKS and C newbie.

Yours in peace,

Jerry

The compiler required for ELKS is documented on the ELKS web site. See the
FAQ section at :-

http://elks.sourceforge.net

Dear Neil,

I've read that page over several times, and there was some info about 
compiling ELKS itself. However, if it does say what to use to compile 
software to run on ELKS, I couldn't find it. Would you be so kind as to 
humor a newbie to C and ELKS and copy and paste in the paragraph or two 
that has it, and I'll forward it to my local LUG friends to explain it 
for me if I can't understand it?

Thanks for your help.

Yours in peace,

Jerry

RE: compiler for ELKS programs

[Neil Holmes]

Hi Jerry,

Here is a cut and paste from the FAQ section.

Q2.2. How do I make an ELKS kernel?
Recent releases contain a compiled binary kernel which most people would be
able to use for initial testing. You should only need to compile your own if
you wish to modify the kernel, or change the configuration options. The file
boot in images.zip can be written to floppy with dd or RAWRITE.EXE to make a
kernel boot disk.

If you want to compile your own kernel, download dev86/Dev86-0.0.13.4.tar.gz
and kernel/elks-0.0.67/elks-0.0.67.tar.gz (or the latest versions) from
linux.mit.edu, or one of the other sites. Unpack Dev86 them into /usr/src
(or any other convenient directory), and elks into /usr/src/linux-86 then
do...

	tar -xvzf Dev86-0.0.13.tar.gz -C /usr/src
	tar -xvzf elks-0.0.67.tar.gz -C /usr/src

The development environment will be created in /usr/src/linux-86, and the
kernel source in /usr/src/elks. Next you have to build the development
tools, which include the bcc compiler:

	cd /usr/src/linux-86
	make install

Next, compile the kernel:

	cd /usr/src/elks
	# Build kernel
	make config
	make dep
	make

And this cut and paste shows you where to get dev86 from. I checked the
link. It works fine.

Q2.1. Where can I find the source?
The primary site http://elks.sf.net

The primary site for Dev86 is http://www.cix.co.uk/~mayday/ which is the
best place to find the latest version.


Hope this helps. Please drop me a line if you need more.

Neil

Dev86 (which may be installed on your linux box already rpm -q dev86 on
a rpm derived distro, linux86 on a debian one) contains a
compiler called bcc.

So if you have a simple c program like a Hello World. Named hello.c 

#include <stdio.h>

main()
{
	printf ("Hello, World!\n");
}

Under linux run:

bcc -o hello hello.c 

This will produce a file called hello which is

file hello
hello: Linux-8086 executable not stripped

You should then be able to run this in your elks environment of choice.

The Red Hat 7.0 Linux RPM installation of dev86-0.15.0-5 does *NOT* appear
to be sufficient to make ELKS images.zip (at least). I found it necessary
to download, untar, make and install Dev86src-0.16.0.tar.gz.

Re: compiler for ELKS programs

[jerryc]

Thank you Paul and Neil,

Based upon that, I should be able to find the coding style requirements
(old style, ANSI, etc) for bcc in the documentation. Any other
suggestions as we progress on this project would be appreciated.

Probably the thing that would be most helpful soon would be some links
or names of good sample code of programs that already use curses or
ncurses for 80 x 25 text screens, particularly ones that scroll both up
and down. If anybody has ideas for anything other than C using
curses/ncurses, now would be a good time to hear them, too, before we
get too commited to that solution.

Yours in peace,

Jerry
