He Kelly, (CC to the vm-dev list) I don't know the answer to your question, but there is a separate mailing list devoted to Squeak VM development that may be of some help. http://lists.squeakfoundation.org/mailman/listinfo/vm-dev - Dave On Sun, Mar 23, 2008 at 10:13:12AM -0600, Kelly Wilson wrote: > Hello everyone, > > > > I recently ported squeak to Syllable OS and it runs with vm-display-null and > vm-sound-null just fine.

Hey everyone, I managed to figure this out. It seems that the vm-display-custom.la file was not being properly output because of some Syllable weirdness. The -lSDL library also wasn't being include correctly for the dynamic lib when being built. Anyways, I just looked at what Linux was doing and tried to build the custom display by hand...this worked. Thanks, K.Wilson P.S. I am sure other problems will pop up...I will post when appropriate.

For the record... that's really cool! Gulik. -- http://people.squeakfoundation.org/person/mikevdg http://gulik.pbwiki.com/ |
Hey Gulik, Thanks for the comment. I have improved
this port for Syllable to the point where I can write directly to the screen
using SDL. I only have a couple events being grabbed and my pixel translations
seem to be off a little because everything is tinged blue?? There is also only an error box
complaining that SqueakV39.sources can’t be found on the opening screen
and another box saying “Reading in stream”? It seems like I am
missing some code…do I have to fill in the ioPrintForm function and the
clipboard functions for the screen updates to work correctly? I haven’t
implemented those yet. Thanks, K.Wilson From:
