How do I compile a .c file on my Mac?
C Solutions
Solution 1 - C
You'll need to get a compiler. The easiest way is probably to install XCode development environment from the CDs/DVDs you got with your Mac, which will give you gcc. Then you should be able compile it like
gcc -o mybinaryfile mysourcefile.c
Solution 2 - C
You will need to install the Apple Developer Tools. Once you have done that, the easiest thing is to either use the Xcode IDE or use gcc, or nowadays better cc (the clang LLVM compiler), from the command line.
According to Apple's site, the latest version of Xcode (3.2.1) only runs on Snow Leopard (10.6) so if you have an earlier version of OS X you will need to use an older version of Xcode. Your Mac should have come with a Developer Tools DVD which will contain a version that should run on your system. Also, the Apple Developer Tools site still has older versions available for download. Xcode 3.1.4 should run on Leopard (10.5).
Solution 3 - C
Just for the record in modern times,
for 2017 !
1 - Just have updated Xcode on your machine as you normally do
2 - Open terminal and
$ xcode-select --install
it will perform a short install of a minute or two.
3 - Launch Xcode. "New" "Project" ... you have to choose "Command line tool"
Note - confusingly this is under the "macOS" tab.
Select "C" language on the next screen...
4- You'll be asked to save the project somewhere on your desktop. The name you give the project here is just the name of the folder that will hold the project. It does not have any importance in the actual software.
5 - You're golden! You can now enjoy c with Mac and Xcode.
Solution 4 - C
In 2017, this will do it:
cc myfile.c
Solution 5 - C
You can use gcc, in Terminal, by doing gcc -c tat.c -o tst
however, it doesn't come installed by default. You have to install the XCode package from tour install disc or download from http://developer.apple.com
Here is where to download past developer tools from, which includes XCode 3.1, 3.0, 2.5 ...

Solution 6 - C
Use the gcc compiler. This assumes that you have the developer tools installed.
Solution 7 - C
Ondrasej is the "most right" here, IMO.
There are also gui-er ways to do it, without resorting to Xcode. I like TryC.
