I want to install a c++ compiler on my ibook running tiger. I've downloaded xcode, but space is at a premium on my drive these days, so I don't want to install the entire package. is there a way to install just the c++ compiler and not all of xcode?

I have not tested this, but it might work.
Mount your Xcode disk image and open its Packages/ folder. Execute and install gcc4.0.pkg and DeveloperTools.pkg.

The installation sizes are:
GCC 4.0.0 -> 168MB
Developer Tools -> 171MB


Extract the .pkg`s with unpkg if you want to take a further look at the files its installing.

didn't work. at least, running gcc -v doesn't bring up anything.

You can use Pacifist (link in my signature) to examine the contents of each package and pull out the parts you want. However, you'll probably need to get a bunch of the support files before gcc will work properly. I'm not sure what all will be required, but you could experiment a bit if you want.

You'd need more than just gcc, you'd need the linker at least and most likely make and autoconf etc. Not so easy to pick out what you want. I suppose you could install all of Xcode and then delete the folder Developer from the root of the drive, but I haven't tried that.

gcc is also included in Darwin, if you want to pickt it out from there - or you could compile it yourself on a different machine (do "make" but not "make install") and install it where you want it. The source to the Apple versions of the developer tools is here:

You can also find the "raw" GCC 4, without the backwards compability extensions Apple includes, att http://gcc.gnu.org/. You'd still need a different Mac to compile it on.
