unable to get _start at 0x00000000

[frnksml]

Hi,

I'm using icc.10.1.016b.i686-linux

I need to have _start at 0x00000000
In my symbols table, I keep getting _start always at some offset from 0.

Snippet of my linker script file.

/* Default linker script, for normal executables */
OUTPUT_FORMAT("elf32-i386", "elf32-i386",
"elf32-i386")
OUTPUT_ARCH(i386)
ENTRY(_start)

/packages/binutils/2.17/lib"); SEARCH_DIR("/usr/local/lib"); SEARCH_DIR("/lib"); SEARCH_DIR

I need to get _start at 0x0.
Anything obviously wrong in my linker script file? Any other ideas?

Hi frnksml,

Hi frnksml,


I got some information that this is a linker question.
Could you send an email to binutils mailing list: http://sources.redhat.com/binutils/?
It can help for you.

Good luck!

Were you able to solve this linker problem? If so please do let me know. You can check with the latest 12.1 compiler to see whether this problem was solved or not.
