compile failure

Greetings- I'm trying to compile from the git sources, based on the 2.6 kernel included on the website. This is an an x86_64 install (originally CentOS 6, but I've got kernel 3.0.4 running on it now)... I'm having a heck of a time getting the DECT stuff to compile in the kernel. my make keeps failing- In file included from /home/jfreeman/linux-2.6/include/net/dect/dect.h:147, from /home/jfreeman/linux-2.6/drivers/dect/coa/sc1442x.c:19: /home/jfreeman/linux-2.6/include/net/dect/identities.h:55: error: field âarcâ has incomplete type make[4]: *** [drivers/dect/coa/sc1442x.o] Error 1 make[3]: *** [drivers/dect/coa] Error 2 make[2]: *** [drivers/dect] Error 2 make[1]: *** [drivers] Error 2 make: *** [sub-make] Error 2 That's the most recent failure, after I removed the enum dect_ari_classes from dect_netlink.h Anyone have any thoughts or suggestions? Thanks- Joe
