1 Building Syslinux 2 3 From Syslinux 6.0 onwards there is support for three different 4 firmware backends, BIOS, 32-bit EFI and 64-bit EFI. To allow users the 5 flexibility to build only the firmware they need the Syslinux make 6 infrastructure has become more complex. 7 8 The Syslinux make infrastructure understands the following syntax, 9 10 make [firmware[,firwmware]] [target[,target]] 11 12 If no firmware is specified then any targets will be applied to all 13 three firmware backends. If no target is specified then the 'all' 14 target is implicitly built. 15 16 For example, to build the installers for BIOS, 32-bit EFI and 64-bit 17 EFI type, 18 19 make installer 20 21 TO build the BIOS and 64-bit EFI installers type, 22 23 make bios efi64 installer 24 25 To delete all object files and build the installer for 32-bit EFI 26 type, 27 28 make efi32 spotless installer 29 30 31 ++++ THE OBJECT DIRECTORY ++++ 32 33 A custom top-level object directory can be specified on the make 34 command-line by using the O= variable, e.g. 35 36 make O=/tmp/syslinux-obj efi32 37 38 will build the 32-bit object files under /tmp/syslinux-obj/efi32. If 39 no object directory is specified then object files will be written to 40 an 'obj' directory in the top-level of the Syslinux source. 41
