Hi,

I'm trying to build 10.5.6's AppleFan.kext, but it's failing as follows:

bash-3.2# darwinbuild -init 9G55

I'm building on a case-sensitive HFS+ image (created using the  
commands in the README), on a 10.5.6 PPC Mac with Xcode 3.0 installed  
(regardless of the above, should I install 3.1.x before compiling  
10.5.6 projects?). The error appears to be correct: the AppleFan  
package contains a Project Builder project rather than an Xcode project.

Thanks,


Jonas

PS: I want to recompile that kext with the debugging code enabled,  
because the CPU B intake and exhaust fans constantly remain at idle  
speed (300 rpm) on my dual G5, resulting in lots of noise from the CPU  
A fans doing overtime as soon as the system gets slightly loaded.

It's not that the CPU B fans cannot spin faster anymore (they work  
fine when the Apple Hardware Test cd tests them), nor that the  
temperature sensors are broken (the temperature sensors of CPU B  
consistently show a higher temperature than those of CPU A). While it  
does not appear to be a (pure) software problem either (booting in  
10.3.4, the OS version the machine originally came with, does not  
appear to solve the problem), I'd like to take a look at what the kext  
is telling the fans to do.
