Rubénerd!

Perhaps its a remnant of my dial-up days, but I'm one of those old fashioned people that keeps local copies of all the stuff I download. Saves me having to download them again if I need to reinstall.

In the case of Xcode 4.x, components are downloaded and installed from the Preferences screen, but you can still keep the downloaded disk images by navigating to:

~/Library/Caches/com.apple.dt.Xcode/Downloads/

Ironically enough, I only remembered this again when I was going through my home folder backups, and realised my Caches folder was way larger than it should be.

I was having trouble compiling Gnumeric from MacPorts and Pan this evening. Turns out gtk2 was failing to build because of a problem with the tiff port.

root# port -v install gtk2
–––> Extracting tiff
On Mac OS X 10.5, tiff 3.8.2 requires Xcode 3.1 or later but you have Xcode 3.0.
Error: Target org.macports.extract returned: incompatible Xcode version
Warning: the following items did not execute (for tiff): org.macports.activate org.macports.extract org.macports.patch org.macports.configure org.macports.build org.macports.destroot org.macports.install
[...]
Error: Status 1 encountered during processing.

If you're being given this error message too, as the error suggests you need to grab yourself a newer version of Xcode. Since I only just reinstalled Mac OS X Leopard on my MacBook Pro I installed the Xcode that came on the 10.5.6 DVD which as the error above shows is only Xcode 3.0.

What's curious is the Apple Software Update has never told me about a newer Xcode. Is it because you need to login as a ADC member first perhaps?

Anyway, lesson learned: make sure you have the latest Xcode before attempting to compile software or built ports on your Mac! It's not that it's darn obvious you should, but that we need reminding sometimes :).
