The past few years I've been working (off and on) porting an open source System 7 application to System 6. Originally I was doing it all by hand, but now I'm using LLMs to help me solve bugs. I've found Gemini to give the most accurate answers to coding issues, but ChatGPT o4-high and o3 work...

Thanks Snial, I will give it a whirl!

If I want to develop an application that targets System 6 what version of CodeWarrior should I be using ? I have an old open source which was originally targeted for MacOS 7+ that makes a lot of C library calls (fcntl, etc) that I would like to get running on System 6. I have been noodling...

Yeah, sorry if that wasn't clear.

Curious if we can come up with a list of Apple Macintosh software that was available for purchase at some point. Off the top of my head: HyperCard Macintosh 68000 Development System MacDraw MacPaint MacProject MacTerminal MacWorks XL (debatable) MacWrite System Software Switcher? Through the...

At the risk of derailing our derailed conversation, I'm curious if I could get feedback on another issue I'm running into. :) In brief, the codebase is using FSpOpenResFile and FSpCreateResFile, which are System 7+ functions. I'm trying to figure out how to correctly create and open a resource...

You know I took a closer look at that Aztec C link and it looks like its for a Dos version that compiles 68k code? I guess in theory it should work since what I've read so far Xinu doesn't use any toolbox/rom routines. I'll send you a link shortly 😀

Woah! Major hat tip @Crutch! Somehow I missed this in my initial research, this is awesome! Well I am loath (playfully) to share the following but it only seems fair. I contacted the Purdue Xinu group regarding getting a copy of the source code for the Mac edition (my book did contain a post...

Curious to hear what books piqued everyones interest from the bibliography. The one I found that I'm slowly going through is Operating System Design: The Xinu Approach (Macintosh Edition) which walks the reader through creating an operating system on the Macintosh. My hope is that after I...

I currently reading through this myself, the chapter 4 FKeys to allow window and app switching are a god send, my only remaining hot key wish is to have a key command to move the current selection in Finder to the trash.

Oh, that might explain why my virtual disk image stoped working after implementing this change; the program was writing temporary files starting with a period...

Here is the solution I ended up with. CodeWarrior Pro N, does seem to have a broken implementation of open for System 6 but luckily we do have access to the source code which is located in Code Warrior:MSL:MSL_C:MSL_MacOS:Src:fcntl.mac.c. In the open function there are two blocks of code where...

Thank so much for these responses! I'm both ecstatic and equally embarrassed to say that I had not realized the source for the c library was included with the complier... so much time wasted. But I'm able to pursue this new path, thanks!

Hello, I am working on porting an old open source project that was originally made to run on System 7 and up, to run on System 6. This is my first foray into classic Mac development, and at best I would consider myself a novice C programmer, but I am slowly making headway. I'm stuck on an issue...
