Hello Gavin, I have not defined BOOST_NO_EXCEPTIONS. I don't know why a small project with qt and boost serialization work and this one no. I tried to add #include before include the serialization header, I don't know if it's correct but seem to fix the problem

What happens if at the very start of your cpp file you add:

#include

#ifdef BOOST_NO_EXCEPTIONS

#error "Oooops"

#endf

Does the #error get hit?

That error at that site suggests that you are compiling with BOOST_NO_EXCEPTIONS defined, which in turn means that you need to define boost::throw_exception yourself before including any boost headers to define what you want to happen when an exception is "thrown" anyway. (Typically a call to abort(), possibly among other things.)

Otherwise, you should remove BOOST_NO_EXCEPTIONS and allow it to throw normally.

If you're not defining this explicitly in your preprocessor options, check if you have disabled exceptions in your compiler options.

I'm not really familiar with Qt but google suggests that some older versions of it disable exceptions by default, but that newer versions might not. Perhaps you need to upgrade. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org https://lists.boost.org/mailman/listinfo.cgi/boost-users
