[linuxsh-dev] Re: LinuxSH4 linker problems

[Adrian S. <adr...@po...>]

Hi,

I had the same problem as Bryan, i.e. ld was bombing out when attempting to
link the kernel. It turned out that the problem was down to lines 7 - 10 in
arch/sh/vmlinux.lds.S specifying illegal formats:

#ifdef CONFIG_CPU_LITTLE_ENDIAN
OUTPUT_FORMAT("elf32-sh-linux", "elf32-sh-linux", "elf32-sh-linux")
#else
OUTPUT_FORMAT("elf32-shbig-linux", "elf32-shbig-linux", "elf32-shbig-linux")

Running sh-linux-gnu-objdump gives: "supported targets: elf32-sh elf32-shl
coff-sh coff-shl coff-sh-small coff-shl-small elf32-little elf32-big srec
symbolsrec tekhex binary ihex", there is no "elf32-sh-linux", etc.

Replacing the above lines with:

#ifdef CONFIG_CPU_LITTLE_ENDIAN
OUTPUT_FORMAT("elf32-shl", "elf32-shl", "elf32-shl")
#else
OUTPUT_FORMAT("elf32-sh", "elf32-sh", "elf32-sh")
#endif

fixed the crash in my case.
Hope this helps.
