Hi ! Linux Gurus
I am working on cluster computing by using the DRBD and Heartbeat. I have problems installed DRBD. (Heartbeat is not installed yet !)

I list below all the relevant files (A,B,C and D). and server information for your easy reference.

Errors message appear after I install (untar Zxfv drbd-0.6.1-pre17.tar.gz) the drbd.

A) The error appear as follow after cd/drbd and do make:
-----------------------------------------------------
[root@node_A drbd]# make

B) drbd_main.c:111 (the line 111,112,113,114)
----------------
#if LINUX_VERSION_CODE > KERNEL_VERSION(2,3,40)

};
#endif

c) Makefile.var
----------------
LINUX = $(shell for S in /lib/modules/$(KERNVER)/build /usr/src/linux /usr/src/$INCLUDE := -I$(LINUX)/include

SUBDIRS = user drbd scripts benchmark documentation #testing

D) Informations about my server setting:
----------------------------------------
Red Hat 7.2
kernel-2.4.7-10
drbd-0.6.1-pre17.tar.gz
gcc-2.96-98

Anyone can point out what wrong with it.
You assistant is highly appreciated.
