For more details about the problem, I found the correct header witch give me this problem, and isolate that with this:
#include <boost/python/detail/prefix.hpp> # include <boost/type_traits/is_polymorphic.hpp> # include <boost/mpl/bool.hpp> #pragma GCC visibility push(default) #include <boost/python/detail/wrapper_base.hpp> #pragma GCC visibility pop #include <boost/python.hpp> BR Renato On Sun, Mar 22, 2009 at 12:36 PM, Renato Araujo <rena...@gmail.com> wrote: > Thanks for the link, I tried a lot of combinations but nothing works > Then I started looking in boost for the header where I got the error, > then I found the header but I don't know why this happen.
