Building CogVM on FreeBSD

Hi,

Here's how to build the Cog VM on FreeBSD.

First, some numbers. Cog, PharoCore 1.1.1, FreeBSD 7.3:

  439108061 bytecodes/sec; 44986622 sends/sec
  484848484 bytecodes/sec; 44903004 sends/sec
  464609800 bytecodes/sec; 45028548 sends/sec
  480300187 bytecodes/sec; 46726917 sends/sec
  485768500 bytecodes/sec; 47229357 sends/sec

4.0.3-2202, a slighly older non-compatible Pharo image, same FreeBSD 7.3:

  525667351 bytecodes/sec; 15328014 sends/sec
  548473486 bytecodes/sec; 14943262 sends/sec
  545260915 bytecodes/sec; 14728594 sends/sec
  545260915 bytecodes/sec; 14600418 sends/sec
  524590163 bytecodes/sec; 14646769 sends/sec

Build the VM on a 32bit FreeBSD boxen.

- Download the sources:

  $ svn co http://squeakvm.org/svn/squeak/branches/Cog/platforms
  $ svn co http://squeakvm.org/svn/squeak/branches/Cog/src
  $ svn co http://squeakvm.org/svn/squeak/branches/Cog/unixbuild

- Apply the following patches from the FreeBSD port of Squeak, found in
/usr/ports/lang/squeak/files:

  patch-platforms__Cross__plugins__Mpeg3Plugin__libmpeg__mpeg3io.h
  patch-platforms__unix__config__configure
  patch-platforms__unix__plugins__PseudoTTYPlugin_openpty.h
  patch-platforms__unix__plugins__SqueakFFIPrims__ffi-config

- Apply the following patch to platforms/Cross/plugins/SqueakFFIPrims/sqFFIPlugin.c:

- Configure the VM as follows in the 'bld' directory:

$ ../../platforms/unix/config/configure \
  CFLAGS="-g -O -msse2 -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0 -DDEBUGVM=0" \
  --without-npsqueak

- Build the VM. Voila.

HTH.

Glad to see your mail make it to squeak-dev, Pierce. I posted some
comments on vm-dev, and I'll reproduce them here. (I don't know if
you're subscribed there.)

Typo nit: this should be

   patch-platforms__unix__plugins__PseudoTTYPlugin__openpty.h

(note the double underscore)

Dump this into a file foo, and add
"platforms/Cross/plugins/SqueakFFIPrims/" in front of the filename, so
you can patch < foo

And building completed without error! I haven't attempted running an
image; I only have terminal access to a FreeBSD machine.

I'd mentioned in vm-dev that it would be really useful to have an image
that only evaluated "3 + 4" and wrote that to stdout. (Maybe someone
already has one?) We could use that with a Hudson instance, and verify
our VM builds automatically.

Actually, you do not need a special image for this. Just supply a start
script when you start Squeak, and run headless using the -vm-display-null
parameter. The script can evaluate 3+4, write output to /dev/tty, then exit.
An example start script is attached.

Excellent!

Turns out I'd only run configure, not make, so when I've figured out
what make's telling me I did wrong (it might be a 64-bit thing judging
by "warning: cast from pointer to integer of different size"), I'll give
it a whirl.

You'll get a lot of these warnings when compiling 64-bit. Many can be
ignored, but some things do not work at all when compiled this way.
If you have specific problems, bring it up on vm-dev (yes I know you
originally asked the 3 + 4 question on vm-dev ;-)

Hi!

I can't get this to work on FreeBSD 8.1... It's a fresh installation, nothing in /etc/make.conf

I'm really happy to see other FreeBSDers out in the community! Would you
mind reposting this to vm-dev though?

i love FreeBSD. It was a first unix system i begun working with more
than 10 years ago.

Do not hesitate to ask about anything on vm-dev or squeak-dev.

Thanks, I've just signed up to vm-dev...

I've been running FreeBSD on my servers for a while, but now I'm trying it on my laptop.  The switchover (from Gentoo) has been fairly smooth, EXCEPT for my essential Smalltalk environment.  Unfortunately, I've had no luck with the latest squeakvm or cogvm!
