Package: binutils
Version: 2.16.1cvs20051214
Severity: important
Hi,
This is my first ever debian bug report, so please be kind :-)
I fail to build a cross-platform binutils when building from
source. I am trying to build binutils (2.16.1cvs20051214) for
mips-linux-gnu on a sparc64-linux-gnu host using gcc 4.0.2-5
and get the following error (due to -Werror):
../../src/bfd/elfxx-mips.c: In function
`_bfd_mips_elf_always_size_sections':
../../src/bfd/elfxx-mips.c:6644: warning: comparison between signed and
unsigned
The problem comes from (as far as I can deduce with my limited
knowledge of binutils and elf) the fact that ELF_MIPS_GP_OFFSET
and MIPS_ELF_GOT_MAX_SIZE produces a signed value rather than an
unsigned value.
The supplied patch fixes this problem by making the two constants
unsigned (beware! lines may have been wraped).
Don't hesitate to contact me if you need more information.
