Syslinux - Jul 2020 - extlinux - Failed to load ldlinux.c32

Thank you for your answer.  I need to correct some information from my 
previous post: booting from `/` did not work either.  I just assumed it 
did based on previous experience.  But with that successful build on 
development branch, it did not either.

I do not succeed building 6.03 nor 6.04-pre1 on slackware current with 
GCC 9 anyway.  This is why I was using the development branch.

v6.04-pre1 make install and installers were complaining so I used its 
binaries right away as such (I tried both / and /boot/syslinux/)

         dd if=./bios/mbr/mbr.bin of=/dev/sda
         ./bios/extlinux/extlinux --install /
         cp -f ./bios/com32/lib/libcom32.c32 /
         cp -f ./bios/com32/mboot/mboot.c32 /

but in the end I got the same error as previously:

	Failed to load ldlinux.c32

Thanks

Hello,

You may consider this answer off topic, but here goes. 

I have already suggested to Patrick that the syslinux package, currently at
version 4.07,  be not upgraded.

Version 6 brings support for EFI, but for that Slackware uses elilo and in my
humble opinion it will be simpler for users to use grub 2.06 for EFI as well as
legacy booting.

I have suggested that grub become the default boot manager in the installer of
Slackware 15.

Best regards,

Didier

Hello Didier, this is the topic exactly.  Why exactly did you recommend 
him not to upgrade 4.07?  I myself sent him a message, attempting to 
push for an upgrade!

Yes GRUB2 is simpler but I would rather like SYSLINUX to become the new 
bootloader.  Not just because the text vs menu flavors look as nice as 
cute as the good old LILO, but because... we can.  We already switched 
to PAM which to me, is unfortunate.  I am afraid that in the end, 
Slackware will be just like like any other distro but its init and the 
absence of package management.  I would be glad to discuss this more 
privately.

Anyhow back to the topic, I managed to use EXTLINUX for loading XEN 
MULTIBOOT before, but now that I try to set it up on another cluster, it 
just fails.  For the record, I finally managed to build 6.04-pre1 on 
Ubuntu 18 (apparently it used GCC 7) but same goes yet again.
