Hello,
I have an error that is puzzling me. I have defined serialization of several custom classes, and everything worked perfectly until we've changed to a new Linux OS and had to reinstall Boost. Now the program doesn't compile and the error given is:
error: incomplete type 'boost::serialization::extended_type_info_null<SetOfRules>' used in nested name specifier
I don't really understand why it says there is an incomplete type when there used to be no errors. The same error happens with all the classes where I've defined serialization.
I'm not too much into the latest gcc developments (certainly others will give a more accurate reply) but it looks like a two-phase lookup issue: at the time your function is parsed SetOfRules is actually incomplete, but the old gcc version you had didn't diagnose it and delayed analisys to instantiation time. This is just my feeling. You might try moving SetOfRules' #include before. --Gennaro.
