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") OUTPUT_ARCH(i386) ENTRY(_start) SEARCH_DIR("/usr/i386-redhat-linux/lib"); SEARCH_DIR("/usr/local/lib"); SEARCH_DIR("/lib"); SEARCH_DIR("/usr/lib"); /* Do we need any of these for elf? __DYNAMIC = 0; */ PHDRS { headers PT_PHDR PHDRS; interp PT_INTERP; text PT_LOAD ; data PT_LOAD; } SECTIONS { /* Read-only sections, merged into text segment: */ PROVIDE (__executable_start = 0x08048000); . = 0x08048000 + SIZEOF_HEADERS; .interp : { *(.interp) } .hash : { *(.hash) } .dynsym : { *(.dynsym) } .dynstr : { *(.dynstr) } .gnu.version : { *(.gnu.version) } .gnu.version_d : { *(.gnu.version_d) } .gnu.version_r : { *(.gnu.version_r) } .rel.dyn : { *(.rel.init) *(.rel.text .rel.text.* .rel.gnu.linkonce.t.*) *(.rel.fini) *(.rel.rodata .rel.rodata.* .rel.gnu.linkonce.r.*) *(.rel.data.rel.ro*) *(.rel.data .rel.data.* .rel.gnu.linkonce.d.*) *(.rel.tdata .rel.tdata.* .rel.gnu.linkonce.td.*) *(.rel.tbss .rel.tbss.* .rel.gnu.linkonce.tb.*) *(.rel.ctors) *(.rel.dtors) *(.rel.got) *(.rel.bss .rel.bss.* .rel.gnu.linkonce.b.*) } .rela.dyn : { *(.rela.init) *(.rela.text .rela.text.* .rela.gnu.linkonce.t.*) *(.rela.fini) *(.rela.rodata .rela.rodata.* .rela.gnu.linkonce.r.*) *(.rela.data .rela.data.* .rela.gnu.linkonce.d.*) *(.rela.tdata .rela.tdata.* .rela.gnu.linkonce.td.*) *(.rela.tbss .rela.tbss.* .rela.gnu.linkonce.tb.*) *(.rela.ctors) *(.rela.dtors) *(.rela.got) *(.rela.bss .rela.bss.* .rela.gnu.linkonce.b.*) } .rel.plt : { *(.rel.plt) } .rela.plt : { *(.rela.plt) } .init : { KEEP (*(.init)) } =0x90909090 .plt : { *(.plt) } .text : { *(.text .stub .text.* .gnu.linkonce.t.*) KEEP (*(.text.*personality*)) /* .gnu.warning sections are handled specially by elf32.em. */ *(.gnu.warning) } =0x90909090 .fini : { KEEP (*(.fini)) } =0x90909090 PROVIDE (__etext = .); PROVIDE (_etext = .); PROVIDE (etext = .); .rodata : { *(.rodata .rodata.* .gnu.linkonce.r.*) } .rodata1 : { *(.rodata1) } .eh_frame_hdr : { *(.eh_frame_hdr) } .eh_frame : ONLY_IF_RO { KEEP (*(.eh_frame)) } .gcc_except_table : ONLY_IF_RO { KEEP (*(.gcc_except_table)) *(.gcc_except_table.*) } /* Adjust the address for the data segment.

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....... -- Summary: Problem allocated section Product: binutils Version: unspecified Status: NEW Severity: critical Priority: P1 Component: ld AssignedTo: unassigned at sources dot redhat dot com ReportedBy: gurvindersinghdahiya at gmail dot com CC: bug-binutils at gnu dot org http://sourceware.org/bugzilla/show_bug.cgi?id=2503 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
