make installkernel errors

[Mani H.]

Hi,

I'm trying out FreeBSD 11.1-RELEASE amd64. Fresh install and without any update I'm trying to follow the instruction from http://www.wonkity.com/~wblock/docs/html/buildworld.html to build and install world with custom kernel.

I created my custom kernel by following http://www.wonkity.com/~wblock/docs/html/kernelconfig.html from GENERIC.

Reason for building and installing the world is to remove:

1. binutils which mainly I want to remove ld and use lld instead.
2. Removing GAMES, EXAMPLES, NLS, ...
3. Removing Debugging tools (this is going to be production/home ;-) server and I don't really need them).

/etc/src.conf

// Want to have [FILE]lld[/FILE] instead of [FILE]ld[/FILE]
WITH_LLD=yes
WITH_LLD_IS_LD=yes
WITH_LLD_BOOTSTRAP=yes
WITH_LLVM_LIBUNWIND=yes

WITHOUT_BINUTILS=yes
WITHOUT_BINUTILS_BOOTSTRAP=yes

// These are what I have concerns about. My custom kernel doesn't include these
// as well
WITHOUT_BHYVE=yes
WITHOUT_DTRACE_TESTS=yes
WITHOUT_HYPERV=yes
WITHOUT_KDUMP=yes
WITHOUT_KERNEL_SYMBOLS=yes

// Since it is going to be a server, I want it to remove these as they are not need. I have them in
// my desktop
WITHOUT_GAMES=yes
WITHOUT_EXAMPLES=yes
WITHOUT_SHAREDOCS=yes
WITHOUT_DOCCOMPRESS=yes
WITHOUT_DICT=yes

Following the instruction from wonkity, everything goes good without any error until I execute:
make installworld KERNCONF=CUSTOM

This ends with so many errors like:

kldxref: error while reading /boot/kernel/libmchain.ko: Bad address
kldxref: error while reading /boot/kernel/linprocfs.ko: Bad address
kldxref: error while reading /boot/kernel/linsysfs.ko: Bad address
kldxref: error while reading /boot/kernel/mfi_linux.ko: Bad address
kldxref: error while reading /boot/kernel/mmcsd.ko: Bad address
kldxref: error while reading /boot/kernel/mrsas_linux.ko: Bad address
kldxref: error while reading /boot/kernel/msdosfs_iconv.ko: Bad address
kldxref: error while reading /boot/kernel/mvs.ko: Bad address
kldxref: error while reading /boot/kernel/mxge_eth_z8e.ko: Bad address

... // Many more (Please let me know if you want me to post more)

I've never seen these error during install kernel and I was wondering someone can help me to fix these.

Thank you,

OK, first off, those instructions are from 2011-2013. Please read and follow https://www.freebsd.org/doc/handbook/makeworld.html

Secondly, you should be able to only install the portions of the release you want during the install process. Installing "world" over the existing system isn't going to remove anything, at least as far as I know.

These days the GENERIC kernel is pretty compact and efficient. Unless you need something that can't be loaded into the GENERIC kernel, dealing with a custom kernel isn't worth it for "home use" in my opinion.

I'm not sure that I'd use lld by removing ld until that is done in the core FreeBSD release, as delivered. Run-time or compile-time options, environment variables, and/or symlinks are much safer options for what is still experimental software. There are instructions on how to do this at https://wiki.freebsd.org/LLD

jef Thanks for your reply. I looked at the link that you posted. The steps are the same as wonkity with more details, but you are correct it has most recent change / information. Regarding lld, in my understanding, that instruction is for before FreeBSD 11.1, since the source for FreeBSD 11.1 contains lld code. But agreed about experimental part.
