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. If you want to try to build a version of Executor, try this: cd src autoreconf --install cd .. mkdir build cd build ../src/configure make That should leave you with a binary called executor (at least on 32-bit x86 Linux systems, or a Mac (Intel or PowerPC) with XCode 3 installed). 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. Now that Executor is using a recent GNU build system, my plan is to use the datadir related variables as a place to install the template for a system volume and to automatically build an ExecutorVolume somewhere (based on environment variables and defaults) the first time Executor is run. 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 may be able to build a copy of Executor by using our old build system and doing something like mkdir -p build/debug-linux cd build/debug-linux ../../util/configure.sh '--host=i486-linux' '--build=i486-linux' '--front-end=x' '--host-gcc=gcc -m32' '--cflags=-fno-strict-aliasing -I/usr/X11R6/include -O0 -finline-functions -g -Wall' '--root=../..' '--host-file-format=glibc' '--sound=linux' '--syn68k-host=i486-linux-glibc' make However, you may find that you need to hand-edit Makefile and change the line BUILD_GCC = gcc to BUILD_GCC = gcc -m32 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. At one time we had Executor running on the Alpha, a 64-bit environment. We actually modified gcc to support "pointer bit-fields" and were able to get Executor to run. Now that 64-bit machines are more popular, I've begun an experiment in supporting 64-bit machines without modifying the compiler. See README.64 for more info. As I continue Executor's transition to a recent gnu build system I may inadvertantly push versions that don't build when using the above commands. Don't hesitate to ask me if you're having trouble compiling, linking or running any of the above platforms. My email address is still , 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. --Cliff Matthews
