[syslinux] 5.01 whichsys.c32 / ifcpu64.c32 does not execute labels

Hello

I am working as developer of archiso (Arch Linux ISO creator). I am
triying to get working with syslinux 5.01 (previously using 4.06).

whichsys.c32 does not execute labels and does not throws any error, just
a help message (the same thing happens with ifcpu64.c32 and ifcpu.c32)

Example:


boot: <<TAB>>
 select pxe sys

boot: whichsys -iso- sys -pxe- pxe -sys- sys
Usage:    whichsys.c32 [-iso- command] [-pxe- command] [-sys- command]
Examples: whichsys.c32 -iso- chain.c32 hd0 -sys- chain.c32 hd1 swap
          whichsys.c32 -iso- config iso.cfg -pxe- config pxe.cfg
boot:

The same things happens if anything command is passed as arguments, ie:

boot: whichsys -sys- coco -iso- pepe
Usage:    whichsys.c32 [-iso- command] [-pxe- command] [-sys- command]
Examples: whichsys.c32 -iso- chain.c32 hd0 -sys- chain.c32 hd1 swap
          whichsys.c32 -iso- config iso.cfg -pxe- config pxe.cfg
boot:

also if I try to execute a c32 file without extension, ie:

boot: whichsys -iso- ls -sys- pwd
Usage:    whichsys.c32 [-iso- command] [-pxe- command] [-sys- command]
Examples: whichsys.c32 -iso- chain.c32 hd0 -sys- chain.c32 hd1 swap
          whichsys.c32 -iso- config iso.cfg -pxe- config pxe.cfg
boot:

But if I pass with .c32, it works, but shows the helper message at end:

boot: whichsys -iso- ls.c32 -sys- pwd.c32
[dir] .                    [dir] i686                       pkglist_i686.txt
[dir] ..                         aitab
[dir] boot                       checksum_i686.md5
Usage:    whichsys.c32 [-iso- command] [-pxe- command] [-sys- command]
Examples: whichsys.c32 -iso- chain.c32 hd0 -sys- chain.c32 hd1 swap
          whichsys.c32 -iso- config iso.cfg -pxe- config pxe.cfg
boot:


I detected this, because it does not work from config file:

---
DEFAULT select

LABEL select
COM32 boot/syslinux/whichsys.c32
APPEND -pxe- pxe -sys- sys -iso- sys

LABEL pxe
CONFIG boot/syslinux/archiso_pxe_choose.cfg

LABEL sys
CONFIG boot/syslinux/archiso_sys_choose.cfg
---

If more info/tests is needed please let me know.

When you tried to use whichsys.c32, could you please provide:
A_ the path for your Current Working Directory?
B_ the path for the cfg file where you have the relevant whichsys.c32 
boot entry?
C_ the path of the boot loader, and which one you used in your tests 
(ldlinux.sys, isolinux.bin)?
D_ the path where you have ldlinux.c32?
E_ the path where you have libcom32.c32?

Maybe with that additional info the issue can be replicated.

Thank you and Regards,
Ady.

boot: pwd
/arch/

/arch/boot/syslinux/archiso.cfg
/arch/boot/syslinux/whichsys.c32

both modes: syslinux and isolinux

* /arch/boot/syslinux/ldlinux.sys ( when installed on VFAT [extlinux -i
/<MNT>/arch/boot/syslinux] )

/arch/boot/syslinux/syslinux.cfg looks like this:

---
DEFAULT loadconfig

LABEL loadconfig
  CONFIG archiso.cfg
  APPEND ../../
---

* /isolinux/isolinux.bin

When booting in this mode directly using "El Torito" or via
"hybrid-mbr-iso": there is a /isolinux/isolinux.cfg with contents:

---
PATH /arch/boot/syslinux/
DEFAULT loadconfig

LABEL loadconfig
  CONFIG /arch/boot/syslinux/archiso.cfg
  APPEND /arch/
---

> D_ the path where you have ldlinux.c32?
/arch/boot/syslinux/ldlinux.c32
> E_ the path where you have libcom32.c32?
/arch/boot/syslinux/libcom32.c32

You may want to ask, "why all these chains?" because in this way, with
only one and the same directory structure and configuration files, we
made posible without any change to boot via all three mode
isolinux/syslinux/pxelinux and selecting if CPU supports 64-bit :)


I made a cutted (just syslinux relevant files) hard disk img (qcow2) for
qemu if you want (1.4MB) at:

and also on /isolinux/ldlinux.c32 to make isolinux works ;)
