Hi all,

Description

When booting from the generated iso, an error is issued :

ISOLINUX 6.03 ETCD Copyright (C) 1994-2014 H. Peter Anvin et Al

Failed to load ldlinux.c32
Boot failed : press a key to retry ...

Configuration Files and environment

[root@hbcs tmp]# uname -a
Linux hbcs 3.10.0-1062.12.1.el7.x86_64 #1 SMP Tue Feb 4 23:02:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
[root@hbcs tmp]# cat /etc/redhat-release 
CentOS Linux release 7.7.1908 (Core)

Steps to Reproduce

Expected Functionality

Boot into your customized linux

Config File

[root@hbcs tmp]# cat /linux-live/config 
#!/bin/bash
# This is a config file for Linux Live Kit build script.
# You shouldn't need to change anything expect LIVEKITNAME

# Live Kit Name. Defaults to 'linux';
# This will be the name of the directory created on your CD/USB, which
# will contain everything including boot files and such.
# For example, Slax changes it to 'slax'
# Must not contain any spaces.
# If you change it, you must run ./tools/isolinux.bin.update script
# in order to update isolinux.bin for CD booting.
# If you do not need booting from CD (eg you're booting only from USB)
# then you can ignore recompiling isolinux.bin, just rename LIVEKITNAME
# and you're done.
LIVEKITNAME="mysuperiso"

# Kernel file, will be copied to your Live Kit
# Your kernel must support aufs and squashfs. Debian Jessie's kernel is ready
# out of the box.
#VMLINUZ=/vmlinuz
VMLINUZ=/boot/vmlinuz-3.10.0-1062.el7.x86_64

# Kernel version. Change it to "3.2.28" for example, if you are building
# Live Kit with a different kernel than the one you are actually running
KERNEL=$(uname -r)

# List of directories for root filesystem
# No subdirectories are allowed, no slashes,
# so You can't use /var/tmp here for example
# Exclude directories like proc sys tmp
MKMOD="bin etc home lib lib64 opt root sbin srv usr var"

# If you require network support in initrd, for example to boot over
# PXE or to load data using 'from' boot parameter from a http server,
# you will need network modules included in your initrd.
# This is disabled by default since most people won't need it.
# To enable, set to true
NETWORK=false

# Temporary directory to store livekit filesystem
LIVEKITDATA=/tmp/$LIVEKITNAME-data-$$

# Bundle extension, for example 'sb' for .sb extension
BEXT=sb

# Directory with kernel .ko modules, can be different in some distros
LMK="lib/modules/$KERNEL"

Hello, I have the same issue as you and I'm using Debian (4.19 amd64). I guess after the step

customize config file (vmlinuz part)

you have to run the script tools/isolinux.bin.update . Maybe isolinux.bin is incompatible with your kernel version. However I've already run the script, it's failed when building the isolinux.bin . Errors were:

ld: cannot find /usr/lib/crt0,efi,ia32.o
ld: skipping incompatible /usr/lib/libgnuefi.a
ld: skipping incompatible /usr/lib/libefi.a
theogfx commented 4 years ago

If you change the LIVEKITNAME var in config, then you should also rebuild the isolinux files (for USB or CD).

Thus when launching ./tools/isolinux.bin.update, you should specify the following-path:

/<LIVEKITNAME>/boot

Don't forget to copy the newly built files to ./bootfiles/ and voilà!

./tools/isolinux.bin.update does not work under CentOS as it is written for Debian. I'd be interested to know the steps required to make this work with CentOS.

What are the names of the files we are supposed to copy? I don't have a diff of the folder contents, and there is not a dedicated subfolder.

Likely it was in the working directory at the time - did a search in the gnome GUI (Ctrl+F ldlinux.c32) and found the second updated copies in the base dir of linux-live-kit (several other copies from slax internal stuff e.g. debian9, debian10) - presumably I was there when I called bin.update.

Copied files with a newer, shared timestamp to linux-live-kit.x.y/bootfiles/ and currently building ...

I am closing all issues to make some cleanup. Please reopen if you still need to, yet I cannot guarantee that I can help with your current issue.
