boost::serialization::null_deleter
Hi! I am using boost::serialization::detail::null_deleter in combination with shared_ptr (on boost 1.34/35) - and I am having a user of my program compiling my program (on boost 1.41) who says he has to change that line to just boost::serialization::null_deleter to get it to work. Should I work around this with pre-processor checks, and in that case - what versions should I look for? Or is there a simpler fix? thanks in advance -- Andreas Ronnquist <andreas.ronnquist@meritkonsult.se>

If something in boost is in a namespace called detail, it's considered an implementation detail. If you use it, you're on your own as far as compatibility goes. In Christ, Steven Watanabe
Hmmm - I'd have to spend more time on it to give a good answer. In any case, the latest version in the trunk - and maybe release - I forgot has null_deleter replaced with something else to fix a bug. Robert Ramey Andreas Ronnquist wrote:

Thanks guys (both Robert and Steven) - I managed to work my way around it by providing a null_deleter of my own: template<typename T> struct null_deleter { void operator()(T *) const {} }; which of course makes me able to compile/run no matter what boost version (in this case anyway).

This is what I was going to suggest :-) but you may find one of the following null deleters better: struct null_deleter { template<class T> void operator()(T *) const {} }; struct null_deleter { void operator()(void const *) const {} };
