A brave undertaking. On a Macintosh, generating a VM is a multi step
First generate the source code for the interpreter.
Time millisecondsToRun: [
Interpreter translate: 'interp.c' doInlining: true.
( this is taken from the Interpreter class ; category --translation ).
Depending on the speed of your machine, this may take a while to run.
This process generates the interpreter, memory manager, BitBlt, etc.
Then generate the support code for the interpreter:
This writes all the source files for the runtime/hardware support code
to the current image directory. I usually place all of the generated
files into a new folder before compiling. On the Mac, a stuff-it file
called 'projectArchive.sit' is generated. Unstuffing reveals two
CodeWarrior 8 project files, Squeak68K.proj and SqueakPPC.proj. (BTW,
CodeWarrior is a C language "development environment"). Compile these
puppies. Almost magically, a couple of new Squeak VMs are generated.
VM generation for other machine platforms is usually a little different.
Generally, the platform support ftp/web sit has the source code and the
make files for that platform.
As a sidebar, Interpreter generates itself through a Smalltalk to C
translation mechanism, which is implemented through class
CCodeGenerator. This is a useful tidbit should you decide to modify the
Amaze your friends !!! Confuse your enemies !!! Build your own Squeak
