Hi,
I am trying to port the u-boot2013:04 to sdk.During compilation,I am running into error:*Undefined reference to _GLOBAL_OFFSET_TABLE*.I checked in u-boot.lds file thr is no definition of _GLOBAL_OFFSET_TABLE.I have added this piece of code in u-boot.lds: .reloc : { KEEP(*(.got)) PROVIDE(_GLOBAL_OFFSET_TABLE_ = . + 4); }
In addition,i see reference of GLOBAL_OFFSET_TABLE.But it is not defined in any file and even linker script. Can anyone please confirm,if this is common issue in u-boot version 2013:04.
which toolchain respectively which gcc and ld version do you use? _GLOBAL_OFFSET_TABLE_ is automatically added by the linker.
For instance If you build qemu-mips with ELDK-5.3 you'll get this in u-boot.map
.got 0x00000000bfc2fe90 0x760 *(.got) .got 0x00000000bfc2fe90 0x760 arch/mips/cpu/mips32/start.o 0x00000000bfc2fe90 _GLOBAL_OFFSET_TABLE_ 0x00000000000001d8 num_got_entries = (SIZEOF (.got) >> 0x2) 0x00000000bfc305f0 . = ALIGN (0x4)
