Syslinux - Sep 2015 - cannot compile simple.c from within Syslinux 6.03

Hello All,

This is my first time requesting help, so please bear with me. I don't
upgrade Syslinux very often (only when the need arises), until now I have been
using version 4.05. However, I have recently acquired several UEFI servers that
are in need of being able to do OS installations via pxelinux.  I have upgraded
to Syslinux version 6.03, however I am not able to compile my custom simple.c
menu program from within /opt/syslinux-6.03/com32/cmenu (it does compiles under
Syslinux 4.05 when I run "make" in the /opt/syslinux-4.05/com32/cmenu
directory).  My PXE server is running RHEL 5.8 x86_64 with the latest updates. I
am compiling simple.c with gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-55).  I see
that the Syslinux "installer" can be built for both the
"BIOS" and "64-bit EFI" by running "make bios efi64
installer", is there an argument that can be passed to "make"
that will build the simple.c32 file for both "BIOS" and "64-bit
EFI"?  I have read through all the documentation that I can find on the web
as well as what is in the Syslinux "doc" directory, but I haven't
been able to find any reference to how build simple.c32 when using version 6.03.
If I run "make" from the /opt/syslinux-6.03/com32/cmenu directory, I
get the following:

[root at SWVT-LINUX cmenu]# make
Makefile:27: /elf.mk: No such file or directory
make: *** No rule to make target `/elf.mk'.  Stop.

Any help that you can provide will be deeply appreciated.

Thank you sincerely,

Kevin Colbert

Not sure about that, I'll let a developer answer.

Actually in case of EFI there is no "installer" AFAIK, just an PE/COFF
image
to be put in its place.

But, why not just use the official binaries instead of rebuilding them?

Such doesn't exist.  syslinux.efi covers FAT* boot and PXE loads in 1
binary.

That should fail.

You'll need to perform your make from the root.  The root Makefile
sets up key variables to control how and where pieces are built due to
the triple-architecture ( bios/ efi32/ and efi64/ ).

Short of a full make, I'm not sure what less you can build without trying

There's still an open discussion regarding certain HP and HPE UEFI systems.

That's unexpected, as Gene explained.  However, you may want to check
out whether the Lua binding of libmenu.c32 in Syslinux 6.03 is enough
for you, in which case you may be able to avoid compilation altogether.
See com32/lua/test/simplemenu.lua for an example.

Just do a plain make bios or make efi64 at the top level.  After the
first run that will only remake what's necessary.
