Installing GCC to Mac OS X Leopard without installing Xcode

I'd like to install gcc to Mac OS X Leopard, and compile some software from source using MacPorts. As http://www.macports.org/install.php has suggested, I've registered as an Apple developer. Now I have to download the Xcode developer tools, but it seems to be enormous. Is such a big download (3.5GB or 1GB) really necessary just for gcc and some header files (mostly for console applications)? Is there a smaller download (possibly on some other site) which would work? Did I find the proper download (Xcode Developer Tools), as required by the MacPorts website?

I don't need an IDE, I don't need any iOS-related software, I don't need big SDKs, I don't want to do any GUI programming.

I don't have an install disk.

There was a similar question Is there a way to install gcc in OSX without installing Xcode? . My question is different, because I wouldn't mind downloading and istalling parts of Xcode to get gcc, as long as it's reasonably large, say 300 MB u开发者_高级运维ncompressed. Is that possible?

At http://developer.apple.com/devcenter/mac/index.action I've found the download link http://developer.apple.com/ios/download.action?path=/ios/ios_sdk_4.2__final/xcode_3.2.5_and_ios_sdk_4.2_final.dmg , which is a 3.5GB download. Based on some answers below, I noticed that Xcode 3.2.5 is for Snow Leopard, and I need Xcode 3.1.4 (1GB) for Leopard, which I can get from http://connect.apple.com/ (titled Downloads and ADC Program Assets) after registration and logging in, clicking on the section Downloads / Developer Tools, then finding Xcode 3.1.4 Developer Tools. The download link is http://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wa/download?path=%2FDeveloper_Tools%2Fxcode_3.1.4_developer_tools%2Fxcode314_2809_developerdvd.dmg .

Maybe this one is right for you: https://github.com/kennethreitz/osx-gcc-installer

I'm using homebrew and everything is fine: http://blog.strug.de/2011/09/homebrew-without-xcode-save-15-gb/

Apple released the command line tools for Xcode in 2012 Feb, the URL: https://developer.apple.com/downloads/index.action?=command%20line%20tools

This tool package includes make and gcc, I searched for a very long time, and finally, Apple released it.

If you download Xcode 4.3 from AppStore for Mac, since the Xcode is packed as Xcode.app and placed in /Application folder, you will have no chance to use the LLVM compiler, nor make utility from the command line.

So, download this package now, if you use Mac OSX Lion (Mac OSX 10.7.3 required), and you need to install some utilities, e.g., mySQL and php mCrpyt module, etc.

Quote from the Apple download site:

This package enables UNIX-style development via Terminal by installing command line developer tools, as well as Mac OSX SDK frameworks and headers. Many useful tools are included, such as the Apple LLVM compiler, linker, and Make. If you use Xcode, these tools are also embedded with the Xcode IDE, and can be installed on your system using the Downloads preferences pane with Xcode 4.3 and later. This package requires Mac OS X 10.7.3 or later.

If you don't have Xcode on a system restore disk, retail copy of OS X, or as an optional installer on your hard drive, you will need to download the appropriate Xcode package for Leopard. Xcode 3.2.5 is only for Snow Leopard, OS X 10.6. For 10.5, the most recent Xcode is 3.1.4 (I believe) which is a 993MB download. When logged in, you should find it in your Developer Download and ADC Program Assets section of the Developer Connection website (you may have to search a bit to find that, though).

Note the Apple-supplied GCC has a number of Apple-developed enhancements, particularly in the area of multi-architecture support, that some open-source projects, in particular, Python, depend on. You may be able to get things to work with a vanilla GCC but is it worth your time and hassle to hack around and test and guess?

GCC is available as a binary package from fink, the other OS X package manager.

Have you thinked about GNU-Darwin ports? There are many binary packages, gcc too, but i don't tried it on my own.

You'll find an (albeit older) version of Xcode on your Mac OS X install disk.

This won't have the iOS bits, etc. (it will have the Cocos Mac OS X development bits however) , but should be all that you require.

The Xcode download is quite big, but if you really want things to work well, you should use it. I've tried other distributions of GCC on the Mac OS X and I've got so much troubles with them... I could not compile PHP without the GCC Xcode distrib for instance.

Apple had released the command line tool in Xcode 4.3.2 in late March 2012.

I found the item can be downloaded from AppStore in Mac or the download section of XCode. GCC might be easier to get familier, and Apple version command line tool is fine to me.
