Subject: [Vm-beginners] Building Cog on FreeBSD

I posted the following to squeak-dev, but it is pending moderator
approval because I've unsubscribed from that list. In case it doesn't
appear there, here it is.

Here's how to build 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:

--- sqFFIPlugin.c.bak 2010-12-03 23:41:56.000000000 +0800
+++ sqFFIPlugin.c 2010-12-04 14:38:02.000000000 +0800

- 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.

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

I can't run an image to test this (does someone have a test image that,
say, just spits the result of 3 + 4 to stdout? That'd be a great testing
tool!) but certainly the build completes without error after the
above-mentioned changes.
