 |
|
Hi all,
I was strolling around in my kernel settings and saw that it was configured for SMP, but I've got only one processor (PIII) so I thought let's disable it. But now the compilation fails. Turned it back on, compilation goes well again. Hmmmm...this is what I get:
In file included from ksyms.c:17:
/usr/src/linux-2.4.19-r1/include/linux/kernel_stat.h: In function `kstat_irqs':
/usr/src/linux-2.4.19-r1/include/linux/kernel_stat.h:50: `smp_num_cpus' undeclared (first use in this function)
/usr/src/linux-2.4.19-r1/include/linux/kernel_stat.h:50: (Each undeclared identifier is reported only once
/usr/src/linux-2.4.19-r1/include/linux/kernel_stat.h:50: for each function it appears in.)
make[2]: *** [ksyms.o] Error 1
make[2]: Leaving directory `/usr/src/linux-2.4.19-r1/kernel'
make[1]: *** [first_rule] Error 2
make[1]: Leaving directory `/usr/src/linux-2.4.19-r1/kernel'
make: *** [_dir_kernel] Error 2
It's talking about : `smp_num_cpus' undeclared. Looks like something is still expecting the number of cpu's here. But I only got one. Any idea's? |

What options do have set for the Processor section?
Did you remember to do a 'make dep' and then a 'make clean' before doing the 'make bzImage'? |

This is what I tried:
(Pentium-III/Celeron(Coppermine)) Processor family
[*] Machine Check Exception
< > Toshiba Laptop support
< > Dell laptop support
< > /dev/cpu/microcode - Intel IA32 CPU microcode support
< > /dev/cpu/*/msr - Model-specific register support
< > /dev/cpu/*/cpuid - CPU information support
(off) High Memory Support
[ ] Math emulation
[ ] MTRR (Memory Type Range Register) support
[ ] Symmetric multi-processing support
[ ] Local APIC support on uniprocessors (NEW)
And I tried changing various setting here, but I have to select Symmetric multi-processing support to get the kernel to compile.
And I issue the normal:
make dep && make clean bzImage modules modules_install |

That is it! I couldn't remember exactly what brought it all back to standard base but you have it. |
