Hi Björn,

I have for a while suspected a problem with the serialization of an „enum class“ item (currently with Boost 1.61 on Ubuntu 16.04), and have written a small test program to further examine any potential problems. While the generated XML looks fine and I cannot see any problems with the enum class, my custom, free-standing „serialize“ function does not get called.

Boost.Serialization automatically converts an enum into an int before
it is serialized.

so what you are saying is that in


x is first converted to an int, and as there no longer is a test_enum to be serialized, my own serialize()-function never gets called ?

Thanks for the hint and Kind Regards,
