| Building Syslinux |
| |
| From Syslinux 6.0 onwards there is support for three different |
| firmware backends, BIOS, 32-bit EFI and 64-bit EFI. To allow users the |
| flexibility to build only the firmware they need the Syslinux make |
| infrastructure has become more complex. |
| |
| The Syslinux make infrastructure understands the following syntax, |
| |
| make [firmware[,firwmware]] [target[,target]] |
| |
| If no firmware is specified then any targets will be applied to all |
| three firmware backends. If no target is specified then the 'all' |
| target is implicitly built. |
| |
| For example, to build the installers for BIOS, 32-bit EFI and 64-bit |
| EFI type, |
| |
| make installer |
| |
| TO build the BIOS and 64-bit EFI installers type, |
| |
| make bios efi64 installer |
| |
| To delete all object files and build the installer for 32-bit EFI |
| type, |
| |
| make efi32 spotless installer |
| |
| |
| ++++ THE OBJECT DIRECTORY ++++ |
| |
| A custom top-level object directory can be specified on the make |
| command-line by using the O= variable, e.g. |
| |
| make O=/tmp/syslinux-obj efi32 |
| |
| will build the 32-bit object files under /tmp/syslinux-obj/efi32. If |
| no object directory is specified then object files will be written to |
| an 'obj' directory in the top-level of the Syslinux source. |
