Cog+NativeBoost @ Mac OS

Hello,

since recently i got access to macs, i were finally able to add NB
support for Mac OS.
I built the Cog VM with NativeBoost plugin , which you can download at
NativeBoost project page [1].

At image side you just load NativeBoost-Installer package
and then evaluate:

NBInstaller install.


Should i also build Squeak VM with NB plugin, or i could stick with Cog? :)

What about adding NativeBoost to the official VMs? There could be a
command line option to enable/disable it. What do you think?

i'm not opposed to this.

If you remember , i proposed to do this for FFI (keep it as builtin,
and enable either via command-line or via .ini file).
That is fairly possible.

Hi Igor,

wonderful, thank you *very* much.

I installed the examples (which appear to be working) and tests as
well, but the tests crash the VM. I have not yet tried to nail the
problem down; is this expected behaviour on the Mac?

Best,
thanks again,

Michael

Hi Igor,

here are some details.

most tests are green, but there are some issues:

1. NBUnixHeapManagerTests - 2 errors ("unable to map to virtual memory")
2. NBCallbackTests - assertion failure in NBInterpreterProxy >> #callInterpreter

I installed NB in a clean up-to-date Squeak trunk image and use the
Cog/NB VM from the NB Google code page.

Best,

Michael

Mac memory manager (NBMacExternalHeapManager) works ok, because it is
involved in a bootstrapping,
and you won't be able to run almost anything without successful bootstrap.
I have to disable this test , or better use an appropriate heap
manager for testing depending on platform.

Yeah, callbacks not ready for Cog. I implemented necessary stuff, but
haven't time
to test it. So, don't use callbacks.
Also, Eliot made something cool with FFI , we yet have to see it, and
basicly i think
i will wait till release of it, so i can play more nicely with it than now.


Also, i haven't time to check all image-side code for compatibility with Mac.
I even didn't tried to do any external library call, i just tested
that assembler + interpreterProxy calls working ok.

Currently the Mac NB code using mostly the linux code, and sure thing
it could be different in some places specific to mac.

Hi Igor,

OK, so those are "expected failures". :-)

Are there any larger bodies of example code that could be used to
identify those places?

Best,

Michael
