odd, but if you do this in the top level directory, it compiles fine: make mrproper cp configs/kernel-2.4.22-i686.config .config make oldconfig make oldconfig make dep make bzImage Note the two make oldconfig commands... haven't figured out why exactly this works yet. *** This bug has been marked as a duplicate of 105978 *** Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031030 Description of problem: I was not able to compile a custom uniprocessor kernel using the normal process: make mrproper make clean make xconfig -> then load in configs/kernel-2.4.22-i686.config make dep make bzImage During the compile, there is a warning on sched.c about implicit declaration of active_load_balance, and the final link process fails, saying that active_load_balance is an undefined symbol. Version-Release number of selected component (if applicable): kernel-source-2.4.22-1.2115.nptl How reproducible: Always Steps to Reproduce: 1. Attempt to compile UP kernel as described above. (Maybe only on P4 machine)? Actual Results: Compile fails. Expected Results: Compile succeeds. Additional info: The problem appears to be in the configuration process - the CONFIG_SHARE_RUNQUEUE option ends up getting set to Y somewhere, even though CONFIG_SMP is not set. active_load_balance is defined in sched.c as an empty function if CONFIG_SHARE_RUNQUEUE is not set, and is defined with a real body if CONFIG_SMP and CONFIG_SHARE_RUNQUEUE are both set, but if CONFIG_SMP is not set and CONFIG_SHARE_RUNQUEUE is set, it is never defined. This is on a Pentium 4 system - maybe it only does this if something detects that the CPU might support HT (this one doesn't)? Anyway, the configuration process should make sure CONFIG_SHARE_RUNQUEUE is not set for a non-SMP kernel. After manually disabling CONFIG_SHARE_RUNQUEUE in the .config file, the kernel compiles properly.
