Compiling on Win95 and Running on the Mac with Codewarrior

Helpful tools for Win95

• A good copy of Unix tools, including Tar and tr
• Codewarrior (of course)

Helpful tools for the Mac

• A good copy of Tar (if Netscape tries to decode it, use right click "Save Link As" to download)
• ResEdit
• Stuffit Expander
• NetPresenz, a good www/ftp server
• And of course, PC Exchange, a control panel included with MacOS 7.X.

How to Compile "Hello World" on the PC and run on the Mac

1. Create a new project with "File / New Project / Mac OS / C,C++ / C,C++ PPC". Put the new project in c:\HELLO. This inserts HelloWorld.c into the new project by default.
2. Change the default name of the executable from "Hello World PPC" to MacHello to make it easier to transfer. You do this by selecting "Edit / Project Settings / PPC Project", and changing File Name under Application Info.
3. Click on "Make" (the little app icon third from the right) (Compiling isn't good enough; you need to Make to get it to link.)
4. You should now have an executable file named C:\HELLO\MacHello; its resource fork is named C:\HELLO\resource.frk\MacHello.
5. Transfer the executable and its resource fork to the Mac.
   1. Make sure your PCExchange control panel is enabled, so your Mac can read and write PC floppies.
   2. Put a blank PC floppy in the PC's drive.

   3. xcopy c:\hello a:\ /s

      This is a cheezy way of copying MacHello and resource.frk/MacHello.
   4. Move the floppy to the Mac, and drag the MACHELLO icon only to a folder on the mac. (Don't drag it onto the desktop; this wouldn't force a copy.)
   5. Set the FileType to APPL and the creator to ???? using ResEdit.
6. Double-click it.

Other ways to transfer the executable to the Mac

• Run NetPresenz on the Mac, and use FTP to put the data fork (C:\HELLO\MacHello) and the resource fork (C:\HELLO\resource.frk\MacHello) into the proper place on the Mac (i.e. the resource and data forks of a single file MacHello). Normal FTP clients don't know how to send resource forks, so you should use MetroWerks' SendMacApp program, which knows how to package up both the data and resource forks into MacBinary format, which NetPresenz understands. need example here
• Create a .tar archive on the Mac using SUNTAR; this automagically converts each forked file to MacBinary format before archiving. You can then unpack that file on a Unix or Win95 system, operate on the files (e.g. check them in to a version control system), repack them with a normal tar program, and transfer them back to the Mac; SUNTAR will decode the MacBinary wrapper when unpacking the archive.
• Share a volume between the Mac and the Win95 system, using some Mac-aware networking software like MacLan for Windows 95.

Where is conio.h? How do I implement kbhit() and getch()?

• conio.h
• conio.c
• conio2.c - I encountered problems with Liechty's version; conio2.c is the version I use now.

I renamed my file on the PC, and when I transfer it over to the Mac, it has the old name. HELP!

The compiler on the Mac can't find a file which I can see is there!

• Make sure the file has a text type of some sort. PC Exchange files are recognized by the IDE but not the compiler! Files unpacked by Suntar are recognized properly because Suntar gives them a generic 'text document' type.
• Make sure there aren't any hidden nonspacing characters in the filename. Something (maybe the IDE?) puts one or two at the end or before the suffix sometimes. You can tell by clicking on the filename in the Finder as if you were renaming it, then use the arrow keys to move from one end of the name to the other; if you have to press the arrow key twice or three times to get the cursor to move, you've found an invisible character. Backspace over it, and all should be well.
• Make sure your access paths are set up correctly (in Edit / Project Settings).
