[gentoo-user] Genkernel doesn't work when module loadable support is disabled
Dear all, I'm trying to generate a kernel without module. So I've disabled Enable loadable module support option with genkernel. Genkernel compiles well the bzimage but fails after with the message ERROR: Failed to compile the modules target... (look hereunder log).

The entire point of genkernel is to make it easy for newbies to compile a kernel, complete with all needed modules, lvm raid support if needed, maybe a splash and an initramfs. I suppose you *could* use the correct options to genkernel to do it, but if you are creating a monolithic kernel then you must know what you are doing, so what you want is: cd /usr/src/linux make menuconfig make copy kernel, System.map, .config and whatever else you like to keep to /boot; edit grub.conf reboot Using genkernel for this is overkill, much like a bulldozer is overkill for digging one hole to plant a rosebush :-) alan -- gentoo-user@gentoo.org mailing list

Then build a kernel with module support enabled. I'm not sure where that error comes from, but it sounds like you do need to heed it. If you *want* a kernel without modules, then enable module loading and make sure all the drivers you need are compiled in. If you *need* to not have module loading, then I'd imagine you have no choice but to compile it manually. p.s. Do you *need* an initrd/initramfs? With no modules I doubt you do, so try genkernel with kernel instead of all. -- Mike Williams -- gentoo-user@gentoo.org mailing list

Although if you did still want to use genkernel to get an initramfs and a nice splash screen, the correct way is: genkernel bzImage initrd It might also be useful for you to read genkernel --help. -Richard -- gentoo-user@gentoo.org mailing list
