I've been using Funtoo on my main desktop PC for quite some time. Now I'm expanding the family building a small (and "weak") NAS and I'd like to have the OS on a USB key, easy to move and clone.
I created a chroot environment on the desktop and installed Funtoo inside it; it all went well, except that when I tried to compile a new kernel ( gentoo-sources-4.15.4 ) the modules_install phase fails: more specifically, depmod.sh fails. As consequence, apparently, the kernel fails to boot.
I tried different methods: manual compilation, genkernel and genkernel-next, all with the same result.
It worth mentioning that the two CPU are different, but both x86_64 and I modified the *FLAGS accordingly.
The two errors are:
./scripts/depmod.sh: line 46: 6113 Illegal instruction "$DEPMOD" -b "$tmp_dir" $KERNELRELEASE 2> /dev/null
*./scripts/depmod.sh: line 58: 6118 Illegal instruction "$DEPMOD" "$@" "$KERNELRELEASE" $SYMBOL_PREFIX
I'm not too knowledgeable and couldn't find a hint from those.
