After compiling *any* project (I have several ones) the .o files in the directory

/MyProject/build/MyProject.build/Debug/MyProject.build/Objects- normal/ppc

have *all* a size between 1 and 1.1 MB - as I have just recognized.

The Objective C code files are (as usual, I think) rather small: most of them 4 KB, the biggest one 32 KB.

Is this normal behavior? And if not: Where may it come from? Inconvenient build settings?

For one of my projects (Mac OS X 10.4.6, Xcode 2.3), the o file sizes vary between 1028 and 181576 bytes, the majority falling in the 20-50 kB range.
So I guess what you're seeing may be influenced by your build settings.


Try building one of the developer examples to see whether the behavior changes from what you see in your own projects. If so, you ought to be able to find the settings that differ in your projects.

As an example I've compiled /Developer/Examples/AppKit/Sketch (again, using Mac OS X 10.4.6, Xcode 2.3) and found most o file sizes in <path to intermediate files>/Sketch.build/Development/Sketch.build/ Objects-normal/ppc to be between 1136 and 191192 bytes, with the majority falling into the 30-90 kB range.

With kind regards

Piers
