Hi, Building c++ project with xcode (MacOS X) I am getting such warnings: "warning std::exception::exception()has different visibility (2) in /Users/dtsachov/dev/evdp/DataObjectImplementationLib/build/Debug/libDataObjectImplementationLib.a(DataTable.o) and (1) in /Users/dtsachov/dev/evdp/TempTestDataObject/build/TempTestDataObject.build/Debug/TempTestDataObject.build/Objects-normal/i386/Test.o" Can anyone have an idea what might cause such warnings. Note - that is a cross platform application and I do not have such warning under windows (using visual studio). Any help is appreciated. Best regards, Denis
