ThinkC [Study Group 0] Getting your Development Environment Setup & Hello, World!

[Daniel Hansen]

Meh, I'd waste a lot of time because a web developper, I'm not.

I can help with this if you want, as I am, it turns out, a web developer. I've already done it in my adaptation of System.css into a WordPress theme (in the works, but the menu behaviour is done):

I appreciate your help but I'm thinking Extreme Long Term about this website (after all, it started out in 2004) and I don't want to impose further recurrent work on you, nor be forced to seek out helping hands. It's really braindead simple to edit in its current form. Anyone familiar with basic html circa 1998 can maintain that website.

I am. Unfortunately, I have other priorities.

Don't worry if you didn't get time to setup your environment yet - when you're ready we'll still be here.

Hi!
Just found the forum a few days ago and figured I'd join the study group!

I'm using a Mac Plus with 4MB RAM. (I would have rather used the SE/30 I acquired a while back, but it needs recapping)

I tried System 7.5.3 and THINK 6 but didn't get too far – there wasn't enough memory to run Hello World

Went with System 6.0.8 (which is what I usually run on my Mac Plus) and THINK C 5.0. So I guess I'll have to skip the System 7-specific content in the book – or get an emulator going.

Anyway, made it through the first two chapters. So far so good!

I'm also joining the party really late, but I found this study group a few days ago, and I'm mega excited about it. What a fun idea! I didn't have the programming chops in the 1990s to build mac programs that would have been any good, but I wanted to SO MUCH.

I'm going to try to do this all on a vintage mac - a Centris 610 I got working a few weeks ago, with Mac OS 7.6.1. It seems to play great with Symantec C++ 6.0 from the bundle of resources provided, but wow it took almost 5 hours to copy that whole bundle to the computer over LocalTalk. I had forgotten how much waiting everything used to require.

 

[Patrick]

WELCOME !

Thats almost the same setup my family had in the 90's including the monitor. except we had a Quadra 610. (which is near enough to be the same for all intents / purposes)

looking forward to what you will come up with!

Ok what is on deck for Session 2?

May I suggest we watch this video and do a small GUI App?

Video: C Programming on System 6 - Demo Application - joshua stein

In addition to some more reading in the book.

Wow, watching that video makes me appreciate modern programming that much more. because holy shit, lots of things done manually thats just transparent today.

Decided to follow along on my 040 IIci:



Been a professional programmer for 17 years, starting out with C and C++, but coding for system 6/7 was a bit before my time.

 

[MacOfAllTrades]

Just a shout-out to Macintosh C Programming by Example as being a good book to teach yourself C on Macintosh using THINK C 5.0

It came with a disk with some skeleton programs used in the book -- and macintoshrepository has the disk. I've used it to build a very simple program but hope to follow along with this study group, catching up in the next few weeks.

Great idea folks!

 

[MacOfAllTrades]

Ok - I'm game!
I was only a little further in using the Macintosh C Programming By Example book but I'll do the study group thing with this C Programming Primer book. It looks good.

The timing will encourage me to stay motivated.

I'm using either an SE or SE/30. Think C kinda of flipped on me when I took the same project that was working on the SE over to my SE/30. Cycling the "Optimize for 68020" preferences checkbox fixed the problem. Pretty weird but if anyone bounces between a 68000 and 68030 and find their programs don't run right / crash, I suggest trying to turn on 68020 optimization and rebuild, then you can turn it off if you want again.

I just learned about this & am excited to jump in (albeit quite late!) to learn some C in a fun way! I'm developing in Mini vMac on a MacII w/ 8MB RAM running System 7.5.5 w/ THINK C v5.0. I've gone through the "ShowPICT" example in Chapter 2 but it breaks in a weird way that I don't understand. I've gone over my code a few times & I don't think I have any bugs in it. When I run it the picture appears but the menu bar goes blank & it won't exit the picture window no matter what I do. Mouse still moves but the computer seems to be otherwise frozen. I have to force reboot to get back to a working state. Any ideas? Screenshot is from a MacSE/4MB RAM in Mini vMac running the built standalone binary. It crashes/fails the same way on both systems.

There's no menu bar in this simple app. It should exit on a mouse button click.

    //while ( !Button() );

You have the main event loop commented out. Re-enable that and it should start working.

You forgot a

That's not it, as it is, it's instructed to simply quit the app right away and go back to the Finder, not hang.

This was me copying/pasting code I was trying to troubleshoot with. The screenshot is of the program running without that line commented out. I pasted in the wrong code here.

Ah! Let me give that a try!

 

[superbenk]

Bingo! It was the missing `InitWindows();`. Thank you!

 

[RickLawson]

Hi are folks still working on this thread?
I am getting my dev env setup but wasn't sure if this was where to post when I start coding?

 

[Patrick]

you are in the right place.
