From your earlier e-mail, libstdc++.so.6 is being built without any version definitions. My conclusion is that for some reason libstdc++ is not using the versioning mechanisms available on Solaris. And that means that, as far as I know, there is no reliable way to tell which version of libstdc++ is installed on a system. This is unfortunate and should probably be fixed one way or another. Please consider filing a bug report about this if there isn't already one. gcc does have a Solaris maintainer, Rainer Orth, and he may be able to look into this. Unfortunately any fix that happens now is not going to help you. Sorry. Ian
