c++ - What do the Boost.Python ImportErrors mean? -

-

experimenting boost.python, stumbled across errors this:

$ ld_library_path=. python >>> import tackle traceback (most recent call last):     file "<stdin>", line 1, in <module> importerror: ./tackle.so: undefined symbol: _zn6tackle12tgamesessiond1ev

now, mean? know importerror, that's straight forward. tackle.so object file failed import, undefined symbol means expected symbol (constructor, variable, ...) not defined, tackle namespace , tgamesession class.

but _zn6, 12 , d1ev mean?

is there documentation regarding these error-messages?

after bit of guessing, found out it's copy-constructor in case. how should know, apart random guesses?
