Could you explain please?
Do you mean that libstdc++ is not binary compatible?


The ABI changed twice, once when we switched from gcc's private
ABI to the multi-vendor ABI, and again when we fixed some bugs in
our implementation of the multi-vendor ABI.

You'll have trouble with C++, whereas C should probably be okay.
Which was it?

C++

There is no binary compatibility between gcc 3.4 and gcc 4.1 C++
libraries.
You have to recompile.  This is not a bug.

Andrew.
