Hi Andreas and Bo,
Please could you clarify build of 64-bit system for 32 bit.

Hello All,
I wonder how to build and test on a 64 bit platform a 32 bit libtool
version.
First test is to use --build=x86_64-gnu-linux --host=i386-gnu-linux
with CC and CXX set to 'gcc|g++ -m32', i.e. multilib .
The libtool regression suite fail in test case :
25: duplicate convenience archive names FAILED
(duplicate_conv.at:83)
From testsuite.log:
....
.../libtool-2.4.2/tests/duplicate_conv.at:83: $LIBTOOL --mode=link
--tag=CC $CC $CFLAGS $LDFLAGS -o cee.$OBJEXT c.lo a/liba.la b/liba.la
stderr:
.../ld: Relocatable linking with relocations from format elf32-i386
(.libs/c.o) to format elf64-x86-64 (cee.o) is not supported
stdout:
libtool: link: .../ld -r -o cee.o .libs/c.o --whole-archive
a/.libs/liba.a b/.libs/liba.a --no-whole-archive
....
Eric PAIRE post a patch about linker emulation mode - ref.
http://lists.gnu.org/archive/html/bug-libtool/2011-06/msg00001.html .
Based on Eric's suggestion I try to build without to set --host, i.e.
as native build for x86_64-gnu-linux with gcc|g++ -m32 as compilers.
As result -m elf_i386 is added to linker (LD) and libtool regression
test pass with:
114 tests behaved as expected.
12 tests were skipped.
Any thought on this ?
