There are a lot of pre-compiled binaries available
for Mac OS X, but sooner or later you will need to compile
something from source. You'll download some gzipped file,
unpack it, cd into the directory, and a README will tell
you to do "./configure;make && make install"
But it didn't work, did it? That's because Mac OS X doesn't
install make or cc or indeed any development tools at all
Fortunately, this is easy to fix. Pop in your install
DVD and you'll see a folder called "Xcode Tools". Click on that,
install it, and you will now have make, cc and everything else
you need to compile that little C code you downloaded.
However, Xcode gives you much more than that. The few little
things you needed aren't even the half of it. Xcode is actually
a complete IDE (Integrated Develpment Environment) for Mac OS X. It's really great stuff,
and right after you get that compile done, I'me sure you will want
to take a look at this. So you open up Applications and..
Huh? Nothing new here. What gives?
No, really, you did install all this stuff. It's just not in
Applications. You'll find it under /Developer at the root of
your hard drive. There's a gig and a half of stuff there.
You can find example projects and prebuilt utilities - it's
really a treasure trove of code. There's a simple example
of using some of this at Xcode for the Rest of Us. You'll
find a good overview at http://www.macdevcenter.com/pub/a/mac/2003/10/24/panther.html and a Google search for "Xcode Tutorials" will turn up much more.
