World: r3wp

sure, I can..let me boot and login to my old mac mini ;)

Ok, let's use PM to reduce the noise :)

ok

Ok, seems we solved the OS X linking issue even for older toolchains.

The trick is to partially link all objects into an (internally resolved) 
single object and then use this to create the shared library. So, 
for Carl's example, that boils down to:

  ld -r -x -o lib.so a.o b.o
  gcc -dynamiclib -o lib.so lib.o

Here's a full package illustrating this:
http://bolka.at/2010/misc/exports2.tar.gz

Sorry, subtle but critical typo in the above. Should be:

  ld -r -x -o lib.o a.o b.o
  gcc -dynamiclib -o lib.so lib.o

Ah, very good. This solution looks like it does what is needed!  
I should have the OS X .so out soon.

The link failed...

ld: lib.o malformed object (section (__TEXT,___textcoal_nt) no symbol 
at start of coalesced section)

Using -t ... the above ld failure happens in the system files, not 
the R3 side.

I've confirmed that /core builds and runs... so this is not likely 
to be related to the gcc update.

Hm, does the link succeed if you leave out the -x option to ld?

yes

Ok. Then try make an unstripped .so from the unstripped .o and strip 
-x the .so afterwards.

I.e.:
  ld -r -o lib.o a.o b.o
  gcc -dynamiclib -o lib.so lib.o
  strip -x lib.so

Actually... I tried that earlier... 1 min...

I misinterpreted the result... that does actually seem to work.

I'll do some tests, and if they pass, will upload the new .so.

Great!

It would also be very neat if you could upload the (stripped) libr3.o 
as well, if that's ok for you. Would allow us to build self-contained 
binaries by statically linking in libr3.

Same for Linux (and FreeBSD, and ...), of course. Not sure if this 
is possible on Windows (I doubt it, actually).

guess it would be a .lib

Yes, but no idea if partial linking is possible with COFF.

(I.e. on Win32.)

A: yes, can export static lib for OS X and Linux.

Lovely!

This libr3.o of which you speak.. that should work for Amiga as well 
shouldn't it?

It would have to be one specific for Amiga, like the dynamic one

I just got compositing working on the Amiga (via AGG).

congratulations!

funny that R3/view ends up working on Amiga before OSX and Linux 
 :-D

Congratulations, Steven. Good stuff

Cool, Steven. Can you upload a screenshot? We like to have material 
to show progress with and I keep a library of screenshots.

Henrik - you better hurry up with GUI, so that Amigans can have some 
useful demos :-)

We are busy going 1.0 on an application these days, so I'm not working 
very much on the GUI. I can however tell that Rebolek and Cyphre 
are hard at work. :-)

Yes, right now I'm working on simple object browser for better debugging 
of styles.

Uploaded OS X libr3.so to github.

Steven, nice!

Cool collaboration on the OS X build

I'll get you updated lib for A110 for OS4.

Ha, great!

Kaj, yes, "Powered by Bolka"

Cool, now work on OS-X can continue ...

Henrik: I have a blog where I'm going to try and document my progress.. 
see http://solie.ca/

ssolie: cool :-)

yes... very :-)

ssolie - cool! Now you could update amigaworld.net R3 thread and 
post the screenshot :-) Btw - you said - "Although these images are 
quite complex they are rendered very quickly by REBOL." - I wonder 
if we have some gfx test scripts for you to try?

aren't those gfx test scripts?

I thought something like FPS measurement, or we have that (I can't 
remember the script name) CPU-REBOL cycles measurement script?

ah yes, that would be interesting to see.

the old 1000-cows script, maybe.
