I too, am having trouble re-building the kernel. I think what you've done is to use the xconfig defaults, not the config that was used to build the initial "vmlinuz" and associated modules. Look in /boot and find the config file there, something like "config-2.4.18-3" and use xconfig to load and save it ... on releases of RH earlier than 7.3 this worked well with the procedure you outline above. On 7.3 and 8.0 I get perhaps 50% thru compiling bzImage and get compile errors ... make[1]: Entering directory `/usr/src/linux-2.4.18-14/arch/i386/kernel' gcc -D__KERNEL__ -I/usr/src/linux-2.4.18-14/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=i686 -nostdinc -I /usr/lib/gcc-lib/i386-redhat-linux/3.2/include -DKBUILD_BASENAME=apic -c -o apic.o apic.c apic.c: In function `get_maxlvt': apic.c:44: warning: implicit declaration of function `apic_read' apic.c: In function `clear_local_APIC': apic.c:64: warning: implicit declaration of function `apic_write_around' apic.c:94: warning: implicit declaration of function `apic_write' =================================================== I'm guessing the header files are not quite current but I haven't had time to continue investigation. ===== There are only 10 kinds of people in the world.
