Yes there is one. You need to declare a variable before the first assignations.

-- Euphoria Code    
atom t0 
integer n 
sequence b_lst, prime_lst 
 
t0 = time()  
...

With n = 10, you get only 4 primes, so you cannot show the ten last ones as you want to do.

You should use

? prime_lst 

instead of

? prime_lst[$-9..$]

After fixing the minor errors:

-- Euphoria Code    
atom t0    
t0 = time()  
   
integer n  
n = 10  
 
sequence b_lst  
b_lst = repeat( 1, n )    
 
sequence prime_lst  
prime_lst = {}    
    
for prime = 2 to n do    
	if b_lst[prime] then    
		prime_lst = append(prime_lst, prime )    
		for i = prime * 2  to n by prime do    
			b_lst[i] = 0    
		end for    
	end if    
end for    
    
? prime_lst    
? time() - t0   

The original error you got was from ld.so, not Euphoria.

libgtk3-nocsd.so.0 was a hack added to prevent the GTK developers from messing with the native look and feel of the window managers on various platforms. It's no longer included in modern linux distros.

Running the corrected source code above with Euphoria 3.1.1 works fine, but compiling it on modern 64-bit Linux (Mint) results in the following error:

init-.c linking /usr/bin/ld: i386 architecture of input file `/home/irv/euphoria/bin/ecu.a(be_machine.o)' is incompatible with i386:x86-64 output

While there might be some kind of work-around to prevent this compile failure, just compiling the program using Euphoria 4.2 is a much better solution. It compiles and runs correctly.

You really should update to Eu 4.1 or 4.2, it has lots of improvements.

BTW, when I run this with n = 10, I get:

{2,3,5,7} 
0 

The linux time command for n = 10 gives:

{2,3,5,7} 
0 
 
real	0m0.004s 
user	0m0.001s 
sys	0m0.003s 
 

I had to change the line n = 10 to n = 20000 to get a non-0 sec runtime.

0.009999999776 
 
real	0m0.011s 
user	0m0.005s 
sys	0m0.006s

Well, complexity is imposed in society in every way, also in the computing world. I'm moving to simpler solutions, that's why I revisited euphoria after some years. Maybe I can use it in some DOS distraction-free, fun context. I really miss a 64-bit modern DOS or at least some modern OS/2. I found FRANK that looks like a good and funny platform to use, so version 3.1.1 would fit the device.

There's also some revival of 3.1.1 in this site.

I'm not convinced that Eu 4 is any more "complex" in use than Eu 3 - the basics are the same.

It's just that with Eu 3, you had to write and debug your own routines to do common tasks, while many of those now come "stock" with Eu 4. You are free to ignore those, and write your own if you wish.

As for "plain DOS" - you can boot up Linux in plain text mode, and run 3.1 or 4.1 programs there. Eu 3.1 and 4.1 for Windows seem to work with Wine, as well, but why bother?

Much better, of course, is to run them in a terminal - which allows you to still have an open browser to check documentation, an editor, etc. all available right there on the screen as you work.

I use a terminal all the time when debugging GUI programs, see photo here: https://drive.google.com/file/d/1cZrkNUlxUUHICAHB7XHgKX2duOQO-R7q/view?usp=sharing

And of course the best Euphoria editor (IMHO) is also a GUI program: https://drive.google.com/file/d/1lXXrNleSwt4suxkcj53UZOgsanWFihNq/view?usp=sharing

Hi Jean-Marc,

So many acronyms: OOEU, LMDE, Gigi, also bindu? Care to explain? Thank you.
