Hi everyone I found problem with compilation drbd kernel module version 8.3.6 on one of our systems. System is xen domU with kernel 2.6.18-r12 . After deeper look into problem i found that module can be compiled without xen compatibility flag set in kernel source, or if xen compatible kernel is set it can be compiled without SMP flag set (if one procesor configuration is set). With combination of these flags it is not possible to compile it. I found that problem is in including APIC definitions. To explain if i put #define CONFIG_X86_LOCAL_APIC into drbd c files, stage1 of compilation is finished successfully. I cannot add it into header files because local header files are included after kernel ones(or is some included into all of c files before kernel ones ? ) Here is my traceback. Traceback: Calling toplevel makefile of kernel source tree, which I believe is in KDIR=/lib/modules/2.6.18-xen-r12/source test -f ../scripts/adjust_drbd_config_h.sh && \ KDIR=/lib/modules/2.6.18-xen-r12/source O=/lib/modules/2.6.18-xen-r12/build /bin/bash ../scripts/adjust_drbd_config_h.sh /lib/modules/2.6.18-xen-r12/source ~/drbd-8.3.6/drbd ~/drbd-8.3.6/drbd Using unmodified drbd_config.h make -C /lib/modules/2.6.18-xen-r12/source O=/lib/modules/2.6.18-xen-r12/build SUBDIRS=/root/drbd-8.3.6/drbd modules make: Entering directory `/usr/src/linux-2.6.18-xen-r12' CC [M] /root/drbd-8.3.6/drbd/drbd_buildtag.o In file included from include/linux/smp.h:18, from include/linux/sched.h:63, from include/linux/module.h:9, from include/net/sock.h:46, from include/linux/connector.h:101, from /root/drbd-8.3.6/drbd/linux/drbd.h:30, from /root/drbd-8.3.6/drbd/drbd_buildtag.c:2: include/asm/smp.h: In function 'hard_smp_processor_id': include/asm/smp.h:76: warning: implicit declaration of function 'GET_APIC_ID' include/asm/smp.h:76: error: 'APIC_BASE' undeclared (first use in this function) include/asm/smp.h:76: error: (Each undeclared identifier is reported only once include/asm/smp.h:76: error: for each function it appears in.) include/asm/smp.h:76: error: 'APIC_ID' undeclared (first use in this function) include/asm/smp.h: In function 'cpu_present_to_apicid': include/asm/smp.h:111: error: 'BAD_APICID' undeclared (first use in this function) include/asm/smp.h: In function 'logical_smp_processor_id': include/asm/smp.h:134: warning: implicit declaration of function 'GET_APIC_LOGICAL_ID' include/asm/smp.h:134: error: 'APIC_BASE' undeclared (first use in this function) include/asm/smp.h:134: error: 'APIC_LDR' undeclared (first use in this function) make: *** [/root/drbd-8.3.6/drbd/drbd_buildtag.o] Error 1 make: *** [_module_/root/drbd-8.3.6/drbd] Error 2 make: *** [modules] Error 2 make: Leaving directory `/usr/src/linux-2.6.18-xen-r12' make: *** [kbuild] Error 2
