extlinux device trouble
Hello,
i'm using version 4.07.
On my computer extlinux does not work.
after debugging, i found the trouble.
in the function parse_mountinfo there was using a function get_string.
in the function get_string there was a line (42) } else if (ch == '\\') {
but in my mountinfo list, there was \ , but not with octal digit.
so the function get_string will fail.
here are some information

[PATCH 0/5] Deleting __intcall() from Syslinux
From: Matt Fleming <matt.fleming at intel.com>
Since we can't use __intcall() for EFI, and since we can now have the
ELF module code resolve all our symbols at runtime, we should delete
as many references to __intcall() as possible and just access the
symbols directly.
The most interesting patch is the support for weak symbols. We need to
be able to reference derivative-specific

It's x86 arch.The reason of compiling pxelinux only is that i want to add tcp support, not http and ftp.

[GIT PULL] elflink fixes
Hi Peter,
The main part of this pull request includes commits that try to replace
as many __intcall() invocations as possible. Some remain, but not many
(and eventually they'll be gone too). There's also a patch to make
better use of ld's --as-needed option and various other bug
fixes/cleanups.
The following changes since commit ff7334a2ce536b7f4b1f6d6f93ff4e285a3bd45a:

syslinux efi64 test c32 module
Hello,
does someone have test syslinux EFI64 bootloader in qemu ?
we have a own c32 module. And some build of this module will hang booting.
Now I will (debug / test) this in qemu.
Is that possible?
if so, what do I need except qemu-syste-x86-64.
And how do I have to start the qemu?
Thanks & regards

Issues with syslinux_run_command(str) and parameters
With the latest 6.03pre I'm seeing an issue where no parameters are passed to the image executed via syslinux_run_command().
An example of this is whichsys.c32, which uses this. E.g., using an example from the wiki page - whichsys.c32 -iso- chain.c32 hd0 -sys- chain.c32 hd1 swap - results in a loop back to the isolinux menu as chain.c32 receives no parameters. Similarly, using -iso- memdisk
