Hi,
I have a set of about 80 projects - a shared framework, 2
applications and about 77 modules. These projects all use the same
prefix file.
The problem is that Xcode precompiles a prefix file for each of my
projects. This is very slow, and at 40MB/project is going to cause
me trouble with disk space on my laptop machine. How can I get
Xcode to share precompiled headers across multiple projects?
I assume you have looked at this: http://developer.apple.com/
documentation/DeveloperTools/Conceptual/XcodeUserGuide/Contents/
Resources/en.lproj/05_09_bs_speed_up_build/
chapter_35_section_2.html#//apple_ref/doc/uid/TP40002695-
DontLinkElementID_175
As I not have that many projects at a time, I did not bother to
change all my projects to use the same file and compiler options.
Therefore, I can not speak from experience.
However, I would be very interested to hear if you had any success
with your setup. Maybe we can save some time and space, too.

On another note, Xcode seems to rebuild the precompiled header if I
look at the settings for a project (look but don't change).
Firstly surely it should be smart enough not to recompile this
unless it really has to, secondly why is looking at settings for a
project or target causing the project.pbxproj to get touched?
This is a really big problem as it can take over 30 minutes to
rebuild the larger projects from scratch!
Cheers,
Steve.
