Hey Robert,
I guess that is possible. I have no idea *why* it is not getting instantiated though so I wouldn't know where to start. Any suggestions?
In any case, what part of the standard says that the return type should be instantiated? I read the part referenced in register_archive.hpp (temp.dep.candidate) but I can't see how to interpret that as "must instantiate the return type."
My implementation of BOOST_CLASS_EXPORT used implementation-specific hacks to get instantiation to happen on different compilers. It all hinges on what the compiler considers to be "using" a name. So you may have to find the right hack for Sun. Fortunately, the code was fairly well localized into a single header IIRC.
Ok, that is a start. Thanks.
Still, why intentionally restrict portability even further when the alternative was not burdensome to begin with? I would have better luck implementing a portable export (the previous version)
Previous to what?
rather than figuring out hacks for each compiler.
Previous to my implementation, there was a nasty #include ordering dependency. That's what I fixed. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
