Thats not necessary as long as you use the right binary for compilation.
For C++ code you should use g++, which automatically will link against the
right libstdc++ and for plain C use gcc which will automatically link
against the right libc

Because there's no libstdc++.so, which usually indicates missing -dev
packages. But anyway, you don't need to search for libstdc++, the compiler
will pick the right one.
