cannot find -lstdc++ (on 64b system)

[paolo...@gmail.com]

I'm not able to resolve this problem when launching ./configure for installation.

The error is:

>> configure:2892: gcc    conftest.c  -lstdc++ >&5
>> /usr/bin/ld: cannot find -lstdc++
>> collect2: ld returned 1 exit status
 
I would appreciate very much some help. Thanks!
 
The machine is 64b w/ Ubuntu 12.04

ia32 libs are installed.
libstdc++.so.6 are available for both i386 and x86_64 in
/usr/lib/i386-linux-gnu/
/usr/lib/x86_64-linux-gnu/
 
That i386 directory is listed in the LD_LIBRARY_PATH :
 
LD_LIBRARY_PATH=/usr/local/lib:/lib32:/usr/lib32:/usr/lib/i386-linux-gnu
 
Just for completeness, here is the configuration setup reported in config.log (output of ./configure):

Configured with:
../src/configure -v --with-pkgversion='Ubuntu/Linaro4.6.3-1ubuntu5'
