It seems that this variable is hard-code by gcc.I cannot change it any
more.When I use gcc -m32 to compile a 32bit program,gcc is looking for
/usr/lib rather than /usr/lib32.But in my system,/usr/lib is a symlink to
/usr/lib64.The real 32bit librarys is in /usr/lib32.The linker is always
complaining about "i386:x86-64 architecture of input file
`/usr/lib/gcc/x86_64-pc-linux-gnux32/4.7.3/../../../../lib/crt1.o' is
incompatible with i386 output.".Why does it not search /usr/lib32?

I thought LD_LIBRARY_PATH was old skool and now ppl use ldconfig, so man
ldconfig.

LIBRARY_PATH is not LD_LIBRARY_PATH.

Well, you can always emerge crossdev and crossdev i686-pc-linux-gnu then... (-:
PS: A quick check on my system shows this:
# [08/12 13:27:52] xenon@ribosome ~ $
gcc -m32 -v --version 2>&1 | grep LIBRARY_PATH
LIBRARY_PATH=/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/32/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../lib32/:/lib/../lib32/:/usr/lib/../lib32/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../x86_64-pc-linux-gnu/lib/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../:/lib/:/usr/lib/
# [08/12 13:28:00] xenon@ribosome ~ $
gcc -v --version 2>&1 | grep LIBRARY_PATH
LIBRARY_PATH=/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../lib64/:/lib/../lib64/:/usr/lib/../lib64/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../x86_64-pc-linux-gnu/lib/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../:/lib/:/usr/lib/
So the lib32 paths are actually included in the library search path,
and correctly placed *before* the lib counterparts. I'm not sure how
your toolchain ends up in the state you described, but it's certainly
weird... Can you please provide the output of "emerge --info" and "gcc
-v --version"? This way people will have more clue to help you...

You have a x32 system?

I think the gcc version with x32 abi is faster.So I install a x32 version
on amd64.Now I have solved my problem by creating a new gcc specs
file.Thank you all the same.
