Executor is a Macintosh emulator that is able to run many ancient Mac
OS 680x0 binaries (System 6 era, early System 7) without using any
intellectual property from Apple Computer.

Executor has not been actively worked on for many years.  It is more
of a curiousity than anything practical; it does not run PowerPC
binaries, nor did it even run most System 7 applications.  Unless you
have a particular application that you know works with Executor, or
just like emulation a lot, you probably don't want to spend any time
with Executor.

Included are a bunch of auxiliarly files and miscellaneous front-ends.

The DOS port required various other libraries that we had permission
to use, but that we did not necessarily have the permission to publish
the source for, so the source to some of the packages that the DOS
port requires is not present in the github repository.

Don't be mislead by configure.ac, Executor currently builds using an
ancient configuration script.  If you want to try to build a version
of Executor for Linux, try doing this (*After you've done a make
install of syn68k):

  mkdir -p build/debug-linux
  cd build/debug-linux
  ../../util/configure.sh  '--target=i486-linux' '--host=i486-linux' '--front-end=x' '--target-gcc=gcc' '--cflags=-fno-strict-aliasing -I/usr/X11R6/include -O0 -finline-functions -g -Wall' '--root=../..' '--target-file-format=glibc' '--sound=linux' '--syn68k-target=i486-linux-glibc'
  make

That should leave you with a binary called executor.  Unfortunately, without
a System Folder, Executor won't even come close to running.  If you're using
a system that can install RPMs and you can dig up and install a copy of
executor-aux-2.1pr16-1.i386.rpm, then you should be able to run.

I'll fiddle around a bit and figure out the easiest way to build a
System Folder for Executor from the git repository and add that info
next.  In the meantime, if anyone is reading this and wants a copy of
executor-aux-2.1pr16-1.i386.rpm, try messaging me (ctm) at github.

If you're on an x86_64 based machine and you have the ability to compile
32-bit binaries, you should be able to build a copy of Executor by doing
something like

  mkdir -p build/debug-linux
  cd build/debug-linux
  ../../util/configure.sh  '--target=i486-linux' '--host=i486-linux' '--front-end=x' '--target-gcc=gcc -m32' '--cflags=-fno-strict-aliasing -I/usr/X11R6/include -O0 -finline-functions -g -Wall' '--root=../..' '--target-file-format=glibc' '--sound=linux' '--syn68k-target=i486-linux-glibc'
  make

However, you may find that you need to hand-edit Makefile and change the line

HOST_GCC = gcc

to

HOST_GCC = gcc -m32


If you have SDL <http://libsdl.org/> installed and would like to use
the SDL-based version of Executor on Linux, you can try:

  mkdir -p build/debug-linux-sdl
  cd build/debug-linux-sdl
  ../../util/configure.sh  '--target=i486-linux' '--host=i486-linux' '--front-end=sdl' '--cflags=-fno-strict-aliasing -I/usr/X11R6/include -O0 -finline-functions -g -Wall' '--root=../..' '--target-file-format=glibc' '--sound=sdl' '--syn68k-target=i486-linux-glibc'
  make

If you have SDL <http://libsdl.org/> installed and would like to play with
the SDL-based version of Executor on Mac OS X Intel, you can try:

  mkdir -p build/debug-macosx-sdl
  cd build/debug-macosx-sdl
  ../../util/configure.sh  '--target=i486-macosx' '--host=i486-macosx' '--front-end=sdl' '--cflags=-fno-strict-aliasing -I/usr/X11R6/include -O0 -finline-functions -g -Wall' '--root=../..' '--target-file-format=glibc' '--sound=sdl' '--syn68k-target=i486-macosx-glibc'
  make

In the past it was possible to cross-compile a version of Executor for
Windows using mingw32.  So far that port hasn't been tried since
putting the code on Github.  It probably doesn't work, but probably
could be made to work without much effort.

My email address is still <ctm@ardi.com>, although ARDI itself is
defunct.  I get a ridiculous amount of spam and will quite possibly
not see email addressed to me.  I'm ctm on github (http://github.com)
and typically check my email there once a day.
