Re: Croquet on FreeBSD?

Howard Stearns
FWIW, I got this working enough to meet my needs - which do not  
include either sound or rendering! I just run routers and a harness.

I don't know enough to say which of what I did made a difference, but  
here's what I did:

1. I added the following ports mentioned by Takeshi-san: emulators/
linux_base8, x11/linux-XFree86libs, graphics/linux-dri, audio/linux-
openal. However, I do not think I made use of the last two.

2. I grabbed 
Squeak-3.sources.tar.gz, and configured using the directions in  
section 1.1 of

3. UnixOSProcessPugin died during make, so I removed it from the list  
in ../platforms/unix/src/plugins.ext. Then make and make install both  
worked. (Thanks for the help, Josh!)

4. The resulting squeak worked ok under X11, and it works headless:
   - A few of the Croquet tests don't work. In particular:
       - the socket reuse test, which allows the same system to be  
both router and participant without using the backdoor. This was ok  
for me because I use the backdoor when I do that.
       - ffi. That hasn't bothered me so far, because I'm running the  
router and a naked harness - no rendering. However, I had to trap the  
failing initialization of OpenAL and use a DummyOpenAL object that  
answers doesNotUnderstand:, ifNotNilDo:, isCurrent, and isPlaying:.
   - I was actually running this over VNC, which I had also installed  
onto the operating system. VNC doesn't tend to support OpenGL, so  
there was little hope of ever seeing Croquet Morphs running.)

So the conclusion is that FreeBSD, as the unix VM source is now, was  
ok for running an "interactivity server", but not for being a normal  
graphical Croquet display.
