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

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

Hello, is there a way to start a efi-application (bios update tool) from syslinux ? best regards Johann

It's x86 arch.The reason of compiling pxelinux only is that i want to add tcp support, not http and ftp. ? 2014-05-08 18:09:15?"Gene Cumm" <gene.cumm at gmail.com> ???

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: Only

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 Johann

Fixed: cp -r syslinux-6.01/com32/libupload/*.h image/usr/share/syslinux/com32/include/ [snip] rm -rf image/usr/share/syslinux/com32/include [snip] cp: cannot create regular file `image/usr/share/syslinux/com32/include/serial.h': No such file or directory The cp is happened in the "libupload" dir, while "rm -fr" is happend in "lib" dir, let "libupload"

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
