Today, I have built isolinux from source code (git://repo.or.cz/syslinux.git) using command
make bios efi64 installer
During the building, I got some errors. For these errors, I must copy /usr/share/syslinux/{mbr.bin,ldlinux.c32...} to the appropriate directories.
Now I am curious how these files such as mbr.bin and ldlinux.c32 are built from scratch？
Any advice will be appreciated!
They are built from source: mbr.bin from the files in mbr, ldlinux.c32 from the files in com32/elflink/ldlinux, etc.
If your build failed, it’s probably because you didn’t have the tools required to build these: nasm and a multilib GCC in particular. nasm is used to assemble the MBR, and GCC has to support -m32 to build the 32-bit loaders on a 64-bit platform.
