Latest binutils-cross-2.20.1-r10.0 build issue with binutils-2.20.1 on gentoo host

[Martin Jansa]

FYI:

If you run into issue
ar: can't set BFD default target to `x86_64-pc-linux-gnu': Invalid bfd target

Like I did in:
http://tinderbox.openembedded.net/packages/601631/

Then here is what I used as workarround/hack:
enabled multitarget USE

unmasked and added keywords for 2.20.51.0.8 version

added --enable-plugins --enable-threads to eclass (as noted in changelog
http://gcc.gnu.org/ml/gcc/2010-05/msg00632.html)

This is not needed and results to broken debian.bbclass (SONAME used
to change package name), because of:
bitbake@jama ~/build.dev.ang.spitz $ objdump -p
/OE/tmpdir-dev/work/armv5te-angstrom-linux-gnueabi/gcc-cross-4.5-r0+svnr160043/packages-split/libgcc/lib/libgcc_s.so.1
objdump: /OE/tmpdir-dev/work/armv5te-angstrom-linux-gnueabi/gcc-cross-4.5-r0+svnr160043/packages-split/libgcc/lib/libgcc_s.so.1:
File format is ambiguous
objdump: Matching formats: elf32-littlearm elf32-littlearm-symbian
elf32-littlearm-vxworks

instead of expected objdump output.

I'll send patch for debian.bbclass changing calling objdump from host
to objdump from binutils-cross (as suggested by khem on IRC).

Yup. I got this breakage too, only binutils-cross version is 2.18-r10.2
and error is:
ar: can't set BFD default target to `i686-pc-linux-gnu': Invalid bfd target

see for example http://tinderbox.openembedded.net/packages/602258/

Though I didn't dig into problem deeply and simply workaround it by
reverting 208ece17f76686e0faa44b2a9223fcadb692a991
But I'll gladly test any patches fixing the issue (whatever it is) in a
proper way.

proper way is to fix binutils on your host.

Ahh, sorry - misread original Martin's post. So it's seems to be
Gentoo-specific problem (yes, my OE is on Gentoo too).
Still wondering why it worked before and how it's connected with adding
"--enable-shared" in 208ece17f766. Weird, because it breaks on building
static library.

it is a latent problem in there which just gets exposed with this change.

Just for reference there is gentoo bug I reported
http://bugs.gentoo.org/show_bug.cgi?id=323319

now it's closed as INVALID

which is not 100% right imho as that broken patch (broken only with
multitarget is applied in ebuild) and --enable-plugins is task for
eclass not upstream.. but you can fix it locally..
