Hi, I have a library, liba, supplied by a vendor that uses libstdc++.so.5 but only exposes a "C" interface. I am trying to build an application with g++ 4.1.1. I have two scenarios: 1) Build a C++ application (with g++ 4.1.1) which uses the "C" functions exported by liba and also uses the Standard C++ Library. So, if I do ldd on my application I see a dependency on both libstdc++.so.5, because of liba's dependency, and on libstdc++.so.6. 2) Use liba to build a C++ shared library, libb, with the g++ 4.1.1 compiler. Then, build a C++ application with g++ 4.1.1 that uses the "C" functions from liba and also uses C++ from libb as well as the Standard C++ Library. So, again, if I do ldd on my application I see a dependency on libstdc++.so.5 (from liba's dependency) and libstdc++.so.6 (from using libb and the Standard C++ Library). For that matter, libb shows a dependency on libstdc++.so.5 (from liba) and libstdc++.so.6 (because it uses the Standard C++ Library). Would either of these scenarios be expected to work correctly in all cases? -- Janet
