libstdc++.so: undefined reference to `_Unwind_GetIPInfo@GCC_4.2.0'

libstdc++.so: undefined reference to `_Unwind_GetIPInfo@GCC_4.2.0'

[Simon Elbaz]

Hi,
The version of my compiler is: gcc 4.3.1
When I try to compile a C++ program, I get this error:

/usr/local/gcc//lib/libstdc++.so: undefined reference to 
`_Unwind_GetIPInfo@GCC_4.2.0'
collect2: ld returned 1 exit status
make[2]: *** [adamad] Error 1

What can I do to compile the program without this error?

Thaks for your help
Simon

Something has gone wrong with your gcc installation.  You need
to install the compiler again.  The most likely reason for this
problem is that you have a mixture of compiler and libraries.

One other possibility to check: you may have an old version of
libstdc++.so in /usr/local and your LD_LIBRARY_PATH points into there.

That was the point. After cleaning old gcc installations and a new 
install, the error is no more present.
Thx
