Anyone Tried to Compile their own Kernel?

[sbeehre]

I Followed this guide http://www.bur.st/~paul/compile_xnu.html but when i go to compile the kernel i get this error

 

cc1: error: invalid option 'cpu=pentium4'
make[6]: *** [WKdmCompress.o] Error 1
make[5]: *** [build_all] Error 2
make[4]: *** [do_all] Error 2
make[3]: *** [build_all] Error 2
make[2]: *** [build_all] Error 2
make[1]: *** [build_all] Error 2
make: *** [all] Error 2

 

anyone know what that means? i would appreciate someone else trying it to see if they get the same error... what i was trying to do was compile a 10.4.3 kernel from the sources.
