Re: internal-error: arm_elf_osabi_sniffer

Hello,

I am working on gdb 6.0.

When I do an 

gdb> arm-elf-gdb helloworld.elf 

I get the following error.

../../insight-6.0.ori/gdb/arm-tdep.c:2747: internal-error: arm_elf_osabi_sniffer
: Unknown ARM EABI version 0x4000000

I looked into the arm-tdep file in the gdb, it seems to be failing at
the function

static enum gdb_osabi arm_elf_osabi_sniffer (bfd *abfd)

where it gets

unsgined int elfosabi = elf_elfheader (abfd)->e_ident[EI_OSABI];

The elfosabi is getting set to ELFOSABI_NONE. 

Then it tries to get the eflags as 

 eflags = EF_ARM_EABI_VERSION(elf_elfheader(abfd)->e_flags); 

eflags is not getting set to EF_ARM_EABI_VER1, EF_ARM_EABI_VER2 or
EF_ARM_EABI_UNKNOWN.

I think that is the problem. Thats the reason it gets to the internal error.

Can anyone throw some light on the issue.

Thank you,
Nagender
