I made a program that embeds a dll to generate a cellular automaton 
image. Could someone test it for me?     http://pastebin.com/raw.php?i=67KtcSK3

windows only

seems to work here  (a big triangle filled with some recursive inverse 
triangles)

yay!

Thanks.

I'm curious. Is there anyway to access a binary function like this 
without writing it to a dll or shared object I wonder?

works here too, xp/pro 32bit.

I'm mostly worried about big endian machines

The triangle is a cellular automaton. This one is a good source of 
randomness according to Stephen Wolfram.

Thank you Endo, Maxim

Works the same for me on W7 64bit.

I need to save some stack space for my evaluation routine runs out 
of stack with the search-depth on 2 (I had expected this but than 
on depth 5 or so)

can unset help? Is there a method to keep track of the stack? To 
see how much you have and use up?

hi all
am trying to use Kaj's 0mq bindings on an aws micro instance.
i have rebol-core 2.7.8.4.3 installed
when i do %ZeroMQ-binding.r2, i get:

Script: "ZeroMQ Binding" (none)
** Script Error: Feature not available in this REBOL
** Where: context
** Near: binary: make struct! [value [binary!]] none
Any ideas?

this works fine on windows7 with rebol-view 2.7.8

REBOL/core does not include the ability to call shared libraries. 
REBOL/View does.

rats

trying rebol-view

now getting this:


./rebol: error while loading shared libraries: libX11.so.6: cannot 
open shared object file: No such file or directory


any experience running rebol-view on aws? looks like some libs/headers 
are missing...

libX11 and libX11-devel are loaded on the instance...

linX11.so.6 is located in /usr/lib64, and i'm guessing that rebol 
is looking in usr/lib

loaded all i686 extensions to the 64bit instance
now get:

$ ./rebol -v
** User error: Bad face in screen pane!
** Near size text self

shouldn't ./rebol -v open the console on linux directly?

note: this is happening with MaxV's http://www.maxvessi.net/rebsite/Linux/
2.7.8 as well

just saw this:
http://www.rebol.org/aga-display-posts.r?post=r3wp226x4139
trying a reboot

no luck with rebooting...

xfonts-100dpi and xfonts-75dpi installed (yum install xorg-x11-fonts-100dpi.noarch 
and xorg-x11-fonts-75dpi.noarch)

damn. >2 hrs and no luck
any ideas anyone?

read somewhere that Xvfb may need to be used - no luck yet... :(

ok - finally got it to launch the console

two more dependencies loaded:
1. xorg-x11-xvfb.x86_64
2. xorg-x11-xauth.x86_64

then:
$ xvfb-run ./rebol -vs

>>

works!

Sujoy, what distro are you using?

Amazon Linux AMI 2012.09

WOW, I didn't know of the existence of Amazon Linux. 

It has a very particular configuration for cloud and not for graphic, 
so you need Xvfb.

:)

took a while to figure out, but i found your posts on altme

However if you have trouble with more "classic" distro, let me know, 
so I'll correct the installer packages. See also this:

thanks MaxV

With Kaj here I've got my own private school, but I still am curious, 
so taking a look here. Goodmorning.

Kaj - i've been trying to run the ZeroMQ bindings on an Amazon Linux 
AMI (took a while to get Rebol View running!)

I have installed and built zeromq from the source, but the result 
is a 64bit build, so rebol complains:

wrong ELF class: ELFCLASS64

would you happen to have a 32bit libzmq.so i can use?

Sujoy - Kaj is still asleep, I will tell him you asked this question 
as soon as he's awake.

:) thanks Natasja

Welcome Sujoy :)

Sujoy, you're in luck; last week I added most dependency libraries 
for Windows to my Red testing repository:

http://red.esperconsultancy.nl/Red-test

They're in the MSDOS folder. The 0MQ library is a bit old, because 
newer available versions are a bit harder to unpack in Windows, but 
it's sufficient for my bindings

Hi Kaj
Am actually trying on an aws instance (amazon linux 2012.09)
would you have the .so files?

Ah, as Natasja said, not very awake yet here. Sorry

I'm not planning to add Linux binaries, as they're very dependent 
on the Linux distribution

true

It would be best to force a 32 bit compile on your AMI. If that's 
problematic, best install some 32 bit distro and extract them from 
there

got it working just as you said. forced a 32bit compile of zeromq
works - i can now do %ZeroMQ-binding.r2 with no issues
