Ah, right, that was the last show-stopper.
BTW, I tried installing Syllable on VMWare 7 and it failed to recognize 
the disk controller (I tried every possible disk modes and Syllable 
boot mode). I might have not picked the right image to install...I'm 
retrying right now with this one: http://downloads.syllable.org/Linux/i686/systems/Server/0.1/SyllableServer-0.1.i686.VM.7z

Oh, that's old. We only got a VMware image contributed for Server 
0.1, so it's much better to run the installation for Server 0.4

hm, kaj, could you try setting
base-address:  -2147483648
and see if that generates binaries which work?
Kaj

But that's Syllable Server, my Linux, so it won't provide any testing 
abilities for Red beyond another Linux
Also, View doesn't run on it. You'd need my unreleased graphical 
version with X11 to run the Red compiler
For testing PIC mode, you'd need Syllable Desktop, for example the 
live CD you got at ReBorCon :-)
Andreas, I'll give it a try

Shouldn't I use one of the VMware v0.6.6 images rather than the install 
CD?
Or should I wait for your graphical version with X11?
Kaj

[1585x2]
You'r mixing up Desktop and Server. 0.6.6 is Desktop, X11 is Server, 
which is Linux
If you want to run Desktop, 0.6.6 indeed has a ready VMware image. 
On the other hand, the live CD you have has some enhancements. Such 
as R3 and the cURL binding :-)

Ah! :-) But can it run R2/View?
Kaj

[1588x2]
Desktop can only run ORCA, Boron and now R3. That's why I've never 
been able to use REBOL in the past decade
Server has R2/Core, Boron and ORCA onboard

Ok, so I need to compile Red/System scripts elsewhere and copy them 
in Syllable.
Kaj

I'm using View on our inhouse Syllable Workstation, which I could 
give you a download for
Dockimbel

copy them => copy the built binaries
Kaj
27-May-2011
[1593]
Yes, I cross-compile everything on Syllable Workstation
Dockimbel
27-May-2011
[1594]
Let me try Desktop first on VMware
Kaj
27-May-2011
[1595]
Wow, base-address	-2147483648 compiles
Dockimbel
27-May-2011
[1596]
Well done Andreas! :-)
Andreas

[1597]
now do the binaries run :) ?
Kaj
27-May-2011
[1598]
I'll have to reboot
Dockimbel

If you can upload the binary somewhare I can test it from my running 
Desktop image.
Kaj

readelf -a looks reasonable
I've compiled the 0MQ binding, and that isn't ported to Desktop yet
Andreas

[1602]
what's the dynamic linker called on syllable desktop? would/should 
/lib/ld-linux.so.2 work?
Kaj
27-May-2011
[1603x4]
No need. It's in the kernel, so it doesn't need to be referenced 
from every binary
I've compiled empty and hello now

Ok, trying to download them (wget?)
Got it
Kaj
27-May-2011
[1609x4]
Wget is not onboard. Curl is
The browser is easiest
Or R3
No, that's only on the live CD
Dockimbel
27-May-2011
[1613]
Runs but doesn't display anything.
Kaj
27-May-2011
[1614]
Look at the end of /var/log/kernel

memmap_instance() RO overlap RW (80000000 + 00001000 -> 80000000)
ERROR : execve(./hello) failed. Too late to recover, will exit
Kaj
27-May-2011
[1617]
That would be the next thing to work on
Andreas
27-May-2011
[1618]
that sounds like something alignment-related is broken
Kaj
27-May-2011
[1619]
Alignment should basically be the same as on Linux
Dockimbel

Kaj, what was the link for Syllable's ELF loader source code?
Just want to have a look at the source, I won't debug it right now, 
I'm still preparing slides for tomorrow's presentation.
Kaj
27-May-2011
[1622x2]
I'll try this again
Kaj: 
I tested the new section headers on Syllable Desktop.

memmap_instance() RO overlap RW (08048000 + 00001000 -> 08048000)"


besides the entry point address being a problem, this could also 
be due to segment alignment, which we basically ignore, at the moment. 
could you try changing "page-size: 4096" to "page-size: 1" and see 
where that gets us?"

Ok
