My current AmorphousDB API (pure virtual) is defined without destructors. It compiles and works just fine on Visual Studio 10 and whatever the current gcc is on Linux.
Earlier versions of the compilers required the the inline definition of a protected destructor to compile without warning. To be completely frank, I didn't even notice that absence of the compiler warnings on my formal API until I looked a few minutes ago. This is a step forward, but somebody needs to decide how far back compilers to be accomodated. As a developer, I don't see anything wrong with requiring a modern compiler. As a user, however, I find it an incredible pain in the ass to have to hunt down and install a compiler, associated runtime, a new gdb, and work through the rats's nest of new bugs, warts, errors, and omissions. But if you really want inter-gcc version pain, try to maintain a subsystem that requires interpretation of Dwarf data. You run into include files with comments like, "If you aren't gdb, you shouldn't be looking at this file." > On Jul 22, 2014, at 8:20 AM, Jim Starkey <j...@jimstarkey.net> wrote: > > Public interface objects should be reference counted with a protected virtual > destructor. > > There are no issues with overloaded functions, though they do complicate the > mapping from object method to flat function names.
