THis is not the fault of Fedora 9 - we run this, too, on some systems, and it works fine here. To me it seems a sif you missed to install a few critical packages on your system.
I agree with you, even though is not easy to find what is missing.
... HOSTCC scripts/mod/sumversion.o scripts/mod/sumversion.c: In function "get_src_version": scripts/mod/sumversion.c:384: error: "PATH_MAX" undeclared (first use in this function)
This probably means that the "kernel-headers" package is missing. Try: "yum -y install kernel-headers" (running as root).
I have checked what you say but, the answer is: "package kernel-headers-2.6.25.11-97.fc9.i386 is already installed on this system"
Could the problem be related to some path not correctly declared?
Many Thanks
Gino
