I should distribute my shared lib (binary) to others, But I must ensure it can run on most linux distributions, I don't know any other method except static linking libstdc++. liba.so depens on: higher version libstdc++.so, libb.so libb.so dpens on: lower version libstdc++.so so I want liba.so not depends on higher version libstdc++.so, what can I do?
