I hv problem when i try to linking the object code file.
the object code file is an example of OSKIT X86 obtained from savnnah unofficial
OSKIT, which i compiled  with the gcc as

$gcc -o hello.o -c hello.c

then i try to link the file with OSKIT libraries with ld as

ld -T ldi.ld -Ttext 100000 -L /usr/lcal/lib -o hello hello.o
/usr/local/lib/oskit/multiboot.o /usr/local/lib/oskit/crtn.o -loskit_clientos
-loskit_kern -loskit_lmm -loskit_c

then i get error as
ld: hello: Not enough room for program headers (allocated 3, need 4)
ld: final link failed: Bad value

then  i try the PHDRS comand of ld and add this in the default script, the
loader script is as follows

/* Script for -z combreloc: combine and sort reloc sections */
OUTPUT_FORMAT("elf32-i386", "elf32-i386",
          "elf32-i386")

but executable build up, when i try to boot from it with the help of GRUB as
bootloader then i get error as

Error:28 no much memory for selected file

press any key to reboot...

Tell me where i am making a mistake in the loader script so that i can correct
thatand run my program fine
i will appreciate any help.......
