MPW 3.0a2 Release Notes

MPW 3.0A2 Release Notes July 14, 1988 Overview This release note pertains to the following MPW products: • MPW Development Environment • MPWPascal •MPWC • MPW Assembler MPW C++ has its own separate release note. This release note, the MPW 3.0 ERS's, and other tool-specific release notes are the documentation for this release. Differences between the ERS, previous 3.0 development releases, and this release are documented below. If no release note exists for something that has an ERS, assume that the piece has been implemented as documented in the ERS. MPW 3.0A2 highlights include a symbolic debugger, project management system, and new C compiler. All of the C pieces of MPW, were compiled with this new C. Since MPW 2.0, the C header files have three important changes: every function has a function prototype, the capitalization for routines that pass strings and points has changed, and the definition of Str255 has changed. The capitalization and Str255 changes will require changes to your C source. See the section below titled ''Interfaces." Another change in MPW 3.0A2 may require a change to your Makefiles. The Pascal compiler no longer uses the Load/Dump mechanism. Instead, the compiled object code for each unit is saved in the unit's resource fork. Therefore, dependency rules (in Makefiles) upon Pascal dump files are obsolete. See the section below titled ''Pascal." The A2 C compiler now has function prototype checking turned on. Furthermore, the C compiler is very strict about type compatibility. Be forewarned ... Installation • Installation horn floppies - MPW 3.0 now includes an installer disk for installing MPW from a set of floppy disks. Here are the steps for automatically installing MPW on your disk: 1) drag the "Installation Folder" onto the hard disk where you want MPW installed 2) launch the MPW Shell found in the ''Installation Folder" Apple Computer, Inc. Confidential Page 1 (the one you just dragged onto your hard disk) 3) the installation script will run and will prompt you to insert a disk in the internal drive. You can insert the MPW disks in any order and it won't hurt to insert a disk more than once. 4) once the installation is complete, throw away the "Installation Folder," and launch the newly installed shell. For those not using the installer script, you will notice that the· configuration of :MPW on the floppies has changed. The files on the disks are in folders that represent their final destination when moved to a hard disk. Pascal, for example, used to be found at the root level of the Pascal disk. Now, however, Pascal will be found in a "Tools" folder on the Pascal disk. This means that there will be duplicate folders across the set of floppies and you won't be able to drag the contents of each floppy onto a hard disk without some conflict. • Installation from Spudsffaters - simply drag the MPW and SADE folders onto your hard disk.
