suresh peri · 05-12-2015, 09:15 AM

Hi,
I am using arm-linux-gnueabihf-gcc cross compiler for building an application for arm cortex a9 board(spear1310)on windows host machine.It is an precompiled toolchain downloaded from the linaro website.
When i generate an .elf file OS/ABI flag value is coming as 0(zero).
ELF Header:
Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00
As I am compiling for ARM OS/ABI flag value should come as 61 .
ELF Header:
Magic: 7f 45 4c 46 01 01 01 61 00 00 00 00 00 00 00 00

can anybody help me out.

Thanks in Advance

Here are the flags used by default for a "beaglebone like" openembedded build.... perhaps you need one of these flags...

arm-poky-linux-gnueabi-gcc -march=armv7-a -marm -mthumb-interwork -mfloat-abi=hard -mfpu=neon -mtune=cortex-a8
