Hello syslinux, I'm a newbie to extlinux, and I'm a developer from yocto project (an embedded linux project). The device or filesystem must be mounted before we can install the bootsector to the device if I understand correctly, for example: $ mount /dev/sdcX /tmp/mnt $ extlinux -i /tmp/mnt Usually, the mount command requires the root privilage, we may not have the root privilage when

In particular, the (./bios/mtools/) "syslinux" command does not need special permissions

Hi! I was looking to download EXTLINUX in the following page : http://www.syslinux.org/wiki/index.php/Download But I do not see that it can be done. It is said that "The SYSLINUX download includes PXELINUX, ISOLINUX and MEMDISK as well." But, there is no word about EXTLINUX Please, advise Thanks Mau

In my last post I pasted the last few line of the compile log for syslinux-3.02pre2. Here are the correct lines from my failed attempt to compile syslinux-3.01. Still the same error. make[1]: Leaving directory `/usr/src/syslinux-3.01/unix' make[1]: Entering directory `/usr/src/syslinux-3.01/extlinux' gcc -Wp,-MT,extlinux.o,-MMD,.extlinux.o.d -W -Wall -Wno-sign-compare
