Mac OS X install gcc compiler
Contributed by macster 
Tagged: Mac system administration Compiling open source projects typically requires a C compiler and gcc is typically the compiler of choice. Mac OS X doesn’t install the gcc compiler by default but it is freely available in the xcode suite of development tools.
To install the gcc compiler, download the xcode package from http://connect.apple.com/. You’ll need to register for an Apple Developer Connection account. Once you’ve registered, login and click Download Software and then Developer Tools. Find the Download link next to Xcode Tools (version) – CD Image and click it!
Find the downloaded package, doubleclick it and follow the installation instructions to install gcc and a host of other development applications. gcc will be located at /usr/bin/gcc.
Websites tend to change over time, so if you notice that the steps to download xcode have changed, please post a comment and I’ll update the recipe.

What if I’m still running Tiger, but the only download I see is for Leopard? The PDF says that the version listed is for Leopard only.
Quinn McHenry said on October 10, 2008
Keep looking down the list.. you’ll need a version 2.x of the developer tools. Like this:
Xcode 2.5 Developer Tools
Xcode 2.5 is an update release of Xcode developer tools, providing bug fixes over Xcode 2.4.1. Xcode 2.5 can be installed on Tiger (Mac OS X 10.4) or on Leopard (Mac OS X 10.5).

Keep searching, IT IS there. I went into the same issue, the default xcode that appear in the page is 3.x, but you need 2.5, it’s the latest for Tiger.
I searched in the site in the developer tools section, yeah I know it’s annoying.

Rich Feit said on March 1, 2009
Thanks much! Minor change — you first click on “Mac OSX”, then there’s XCode Tools in the resulting list.

Hi,
Thanks for the instructions. The path has changed slightly.
Once you log in, go to: Downloads -> Developer Tools -> Xcode 3.1.2 Developer Tools and download the package called Xcode 3.1.2 Developer Tools DVD (Disk Image)
Cheers!

The ‘gcc compiler’ is installed when one installs ‘XcodeTools’ (via the ‘XcodeTools.mpkg’ file) from the installation CD (if installing Panther [MacOS X 10.3.x] or earlier) / DVD – in the ‘/Xcode Tools/’ folder.
Or, in the CDs’ / DVDs’ ‘/Xcode Tools/Packages/’ folder is / are the ‘gccx.x.pkg’ (where s.x is the version number) installer file(s).

I like the Apple sucks for 1GB download for GCC. It is really good. Try!

GCC-4.0 requires 95mb when installed from your OS X DVD.

Some Apple forum members managed to figure out that the most up to date and final release of Xcode for Tiger is v 2.5. You can find the link to the Xcode package at http://discussions.apple.com/message.jspa?messageID=7769749

Sorry if i am repeating anyone but I know if you have mac 10.4.X then on the install disk you can find a copy of xcode…

Hi,
I’ve been installed the powerpc-apple-darwin9-gcc-4.0.1. I’m now concerned with an error message from typing ‘gcc -Version’ into console:
”powerpc-apple-darwin9-gcc-4.0.1: couldn’t run ‘/usr/bin/powerpc-apple-darwin9-gcc-ersion’: No such file or directory”
This seems to be obvious, because the letter ‘v’ from version is missing. But where have I look at to correct this mistake ?

The GNU Compiler for Java (GCJ or gcj), a free software compiler for the Java programming language, forms part of the GNU Compiler Collection…. The GNU Compiler Collection is a full-featured ANSI C compiler..

I have an Mac with OS a version 10.5.8. I recently installed Xcode v3.1.3 and I started to get errors and warnings in compiling programs with gcc, such as:
” ….. incompatible implicit declaration of built-in function ‘ceil’ ”
Can someone help me?

Can you tell me how to install CGAL in MAC
Kurt Bigler said on November 7, 2009
As a long-time XCode user it has been installed on my Mac for years, and I have applied updates occasionally. Nonetheless gcc is not located at /usr/bin/gcc (which has not been an issue until now since I don’t normally use the command line for compiling). It is however, located at /Developer/usr/bin/gcc. So I added /Developer/usr/bin/gcc to my path, hoping that would let me use gcc and make to build libjpeg under Leopard. (Aside: Apple’s own jpeg support via “Image IO” appears to ignore the specified “quality” for jpeg compression).
However the ./configure script for libjpeg says:
configure: error: installation or configuration problem: C compiler cannot create executables.
But at least now that I altered my $PATH it recognizes that gcc is present.
I have not tried to debug the configure script, but figure I am missing something basic, or else XCode installation practices have changed. My XCode is 3.1.1, and gcc from the command line says “i686-apple-darwin9-gcc-4.0.1″.
Kurt Bigler said on November 7, 2009
FIXED: I installed XCode 3.1.4 and it resolved the problem. It also installed gcc in /usr/bin so I no longer have to alter my $PATH.

I have an important question. You mentioned that you chose to ignore ring settings in this paper enigma machine. I have been trying to get the ring settings working by cutting each paper strip in half and shifting the right side by the appropriate ring offset..eg to the 2nd position if the ring is B offset. If all the examples have a GAAA and RAAA setting, I get the paper enigma to match the enigma simulators, but if I try any ring offset, the results don’t match. I went to the rotor details in Wikipedia and tried to replicate their results with GAAA and RBBB to get EWTYX to no avail. Could you please help tell me how you would get this to work right if I cut your strips in half and rotate 6 different rings instead of 3?

Is there any way to download a mac compiler with having an account with Apple? Because it is $100 a year. I just dropped my account because I felt like that was way too much money to spend every year for what Apple offers you. Plus If I get an account and download the compiler, if I don’t renew my account I think the compiler will stop working just like my email stopped working.

Apparently it’s possible to become a developer without signing up for any of their programs. Becoming a developer is free, and at that point you can download Xcode.

I hate this because I dont want to install xcode. I just want gcc. Xcode is a >2gigs .dmg (with the ios sdk) when gcc is much smaller. It’s pretty ridiculous when you have to install unnecessary and unwanted things to get a basic staple of computer programming.
This is why apple is awful. I do not want your IDE, I most certainly do not want the bundled iphone SDK (and I cannot find a non-bundled version from apple’s dev. site). I just want gcc (which should come with osx by default).
Sorry but osx is for children with over-protective children.

I just installed it. I’m frustrated. I installed the package, it told me location is “Mac Harddisk”. That doesn’t give me a path. In theory, it should be in /usr/bin?
Nothing is there. It claimed to copy over 93 MB but didn’t do anything? How can I tell if this was actually installed?
Jnkm 89 said on October 23, 2010
you can get gcc from their website ( http://gcc.gnu.org/ ) and install it yourself. downloading xcode is just one way to get it installed on your computer. Learn how to use the web before make these ignorant/moronic comments.

It’s not just a gcc compiler, it’s a whole development package including many other applications.

It looks like apple is forcing us to pay $100 to get this xcode software, is there another way?
Rebegol said on June 25, 2011
I had a lot of trouble with this today — only since xcode 4 came out is xcode 3.0 no longer available (it was free). You can pay about $5 for Xcode 4. However, your installation disk will have the right version of xcode for your operating system on it (for free). I upgraded to Snow Leopard and on the install disk, Xcode is an optional feature that does not install unless you ask it to.So look to the disk rather than the internet — I couldn’t find xcode free anywhere.

Quinn can you convert on a mac a doc that looks like a page which should really be a zip file?
Allen Liu said on September 3, 2011
I had the same issue of installing xcode but still could not find GCC. Try searching for “install xcode” through Spotlight and run that first file. That should do it. Took me a while to figure it out. Hope this helps!
tokeiten said on September 13, 2011
Try:
/Developer/Applications/Xcode
it works beautifully !
tokeiten said on September 13, 2011
if what you want, is not the Xcode IDE but just the plain compiler type:
gcc filen_name -o output_file_name
or try:
man gcc
good luck!
Kebman said on January 16, 2012
Does not work. You have to pay to download Xcode. I still need GCC, tho.
Kebman said on January 16, 2012
My bad, seems to work now. :p Had some problems downloading Xcode for older OS X’es.
