Would it help if my client installs the newer libstdc++.so of gcc 4.2.2? His program built with old gcc should continue to work, and ldd (or dlopen) of my shared library should also work? The interface to my shared lib is C style interface, so hopefully all would be fine? Please let me know whether this is a feasible approach? Thanks. Qingning
