Try taking out the "export" and see what it gives you for an error. The "duplicate" I got reported was on a source line that doesn't exist, supposedly from a simgear header file!

Sorry I mistyped thatit should have been "extern" not export :-/ Andy Ross <[EMAIL PROTECTED]> said: > David Megginson wrote: > > Alex Perry writes: > > > Do we care about this error ? > > > /usr/bin/ld: Warning: size of symbol `current_model' changed from 4 to 8 in ../../src/Model/libModel.a(acmodel.o) > > > > Yes, I'm getting this as well and I don't understand it. > > It's a symbol collision.

It's a symbol collision. There's another "current_model" defined in LaRCsim/ls_model.c. Renaming one of them fixes the issue. Why the linker doesn't detect this as a vanilla multiple-definitions collision, instead of that weird size mismatch, though, is beyond me. Andy -- Andrew J.
