Does Qt need to keep BC across incompatible standard C++ library implementations? (Independently from the long term/short term ABI breaks) This does not mean "is Qt affected by a BC break in the standard C++ library that you used to compile Qt", the answer to that is yes (Qt uses the standard library internally). * pros: ** You can use Qt compiled against either libc++ or libstdc++, with "the other one", without recompiling Qt. * cons: ** End users applications using anything coming from the standard library still need to be recompiled; what's the problem at recompiling Qt too? (If the end user application is NOT using the standard library then this whole discussion is void) ** We can't expose std:: datatypes in our ABI, only in inline functions, losing significant functionality (and possibly performance) * subjective cons: ** apart from Qt, noone does that, why should Qt be special in that regard? ** is there anyone really using this feature?
