Ok, here is my dillema. I'm trying to learn C and use Apple's Project Builder. But i cannot figure out how to compile with it. Any help would be great. I'm very new to programming btw.

I am in the same boat as you. I too cannot get Project Builder to built C files.

So I use the terminal to compile.

cd /name/ofthedir/
cc -o appname HelloWorld.c

this will produce the appname program wich you can run by typing ./appname

Command line is how I usually compile short Ansi C programs. However if you really want the comfort of Project Builder, create a project file by selecting "New Project" from the file menu, and in the assistent that pops up, scroll all the way down until you find "Standard Tool" (it is in the tools section, so you might have to click the diclosure triangle next to "Tools" if it's not shown). This works on the april beta dev tools, but I suppose it's the same in other versions, too.
PB creates a new main.c file (which defaults to the usual Hello World program) that you can then edit. Compile and run it by clicking the Hammer and Computer Screen button, your new program's output will appear in the Project window.

HTH, Seb.

Have you guys tried making Project of type "C++ Tool"? Obviously, it's not straight C, but I think it would work for you.

Edit: OK, Seb G, what's the difference between "C++" and "Standard" Tools? is "Standard" straight C?

Yes, "Standard" is plain C.

thanks seb j, that seemed to work. I'll have to play around with it until i'm sure but thanks.

From the terminal shouldn't the compile command be gcc? Everything I have read says Apple's compiler is based on gcc, but when I try to use it, it returns file not found. I have not tried just cc, but I will now.

guys, there's a tweak w/ PB and C code (unless it's been updated recently), that makes actually running C code pretty much futile, in it.

#1, make your project a Standard Tool, when you create the Project Space, that'll allow you straight C code, instead of C++.

#2, when you compile and run your code, it won't seem like it works. Feed it all the inputs you ask for in the code. after it get's all the inputs, it'll spit out all the outputs.why? I have NO clue. but, it does.

Solutions:
A. run the code using the debugger. The debugger runs everything in the right order.

B. Command line. use it, bond with it, it is your friend. learn Vi, or emacs, or any of the bazillion other command line text editors that exist. Compile in command line, using gcc (cc didn't work w/ 10.1.4, haven't tried after the latest update). if you type gcc main.c it'll create an a.out file in the same directory. use -o, it'll be named something else. run by typing ./a.out. g'luck, guys
