Interesting.

I just posted to the Cocoa list (probably the wrong place actually) because Ive had exactly the same problem. I compiled from scratch (cleaned all) and have been using GCC 4 for some time. I dont think any of my targets are straggling on v3.3.

Maybe there is more to this that meets the eye.

PS - I still havent solved this...what level of debugging symbols do you have turned on Robert?

A quick check (admittedly on 10.3.9, not Tiger or Xcode 2.2, but this should hold true anyway) shows that std::__ioinit was defined in libstdc++.a, but it isn't part of libstdc++.dylib. The .a is used when building with gcc 3.3 or later, while the dylib is used with gcc 4.0.


That leads me to guess that there's a static library in your project that hasn't been rebuilt with gcc 4.0, part of your project is building with 3.3 and another part is building with 4.0, or you've inadvertently switched compiler versions for your project as part of moving to Xcode 2.2.

Hope this helps,
Eric
