The file format for my kernel is a mz exe file, i use a bootloader call bootprog to load it, as it can load com or exe files put anyware on the disk, this mean it very easy for testing, and will also run from dos.
I thing the best file format for programs run in your OS would be a bin file with simple header. NOTE: This is for a OS writen in 100% ASM. |

Does the djgpp linker support ELF?
Try the following with the djgpp ld to see what formats it supports. This was issued under Cygwin. Since Windows can't load an ELF file, that format is not supported under the Cygwin toolchain. Code: $ ld -V GNU ld version 2.16.91 20050610 Supported emulations: i386pe If for some reason the djgpp linker does support elf, you could direct it to use that output format like this (assuming elf_i386 was listed): Code:
$ ld -m elf_i386 ...

I don't think DJGPP by default supports ELF, but try the following (untested by me but might work):

On my Os i use 'txt' source files, because programs are assembled at load time ,i found this is the simpler solution. I also use ELF relocatable for programs written in 'C' but don´t know if it is better than the other formats.By default djgpp do not support elf but if the links given by Rugxulo works ,then you can download binutils wich supports elf format. |

Yeah, I have it, not sure why people keep having trouble downloading that file though. That's really weird.
It's too big to attach here, so e-mail me, and I'll send it to you. |

I have a Gmail account too, and I think they don't allow binaries in .ZIPs, but I'll send it UHarc'd, okay? (should be smaller anyways)
