CFM-68K is a runtime architecture for 68K-based Macintosh applications and shared libraries. This architecture is modeled after the Power Macintosh runtime architecture and uses the CFM (the Code Fragment Manager) to provide shared library support for 68K Macintoshes. CFM-68K runtime applications and shared libraries can coexist and run simultaneously with classic 68K runtime applications.
CFM-68K Runtime Software Installation
The CFM-68K runtime software requires System 7.1 or later, 32-bit addressing to be turned on, and a 68020, 68030, or 68040 Macintosh system.
To install the CFM-68K runtime software and related shared libraries, drag the file called CFM-68K Runtime Enabler, as well as all the shared library files in the folder, from the “:CFM-68K Additions:” folder to the System folder icon (not into an open System folder) on your 68K-based Macintosh system. This copies the files into the Extensions folder. After installation, reboot your system.
Documentation on how to develop software that takes advantage of CFM-68K is in the "Bldg CFM-68K Runtime Programs" folder.
CFM-68K version 1.0.4
CFM-68K version 1.0.4 contains bug fixes to Mixed Mode for 68K.
• In previous versions of CFM-68K, the _MixedModeDispatch trap was not implemented. Calling NewRoutineDescriptor, NewFatRoutineDescriptor and DisposeRoutineDescriptor would result in an unimplemented trap system error. The trap is now implemented and it is safe to call all three routines.
• A bit was added to the gestaltMixedModeAttr so that software can detect that the Mixed Mode manager routines are implemented. This new bit is gestaltMixedModeCFM68KHasTrap. The Mixed Mode interface file, MixedMode.h, has been updated to support this new bit and new routine names have been added to allow calling the trap routines from classic 68k. This interface file is available on E.T.O. #20 (and later).
