Description

Mario would like to incorporate his Hilbert scheme code, but to do so he must compile with c++11 (because he uses several c++11 features).

How to do this while maintaining backward compatibility?

History

#1 Updated by John Abbott about 7 years ago

  • Priority changed from Normal to Urgent

Mario makes essential use of various C++11 featues (e.g. auto variable declarations).

The problem is that CoCoALib continues to use std::auto_ptr which triggers numerous, annoying compiler warnings.
Issue #999 tackled the problem by setting a compiler flag -std=c++03. This correctly suppressed the warnings, but does not solve Mario's problem.

Possibilities are:
  • enforce -std=c++11 and set the g++ flag -Wno-deprecated-declarations (but how portable to other compilers?)
  • replace use of std::auto_ptr by std::_unique_ptr (or whatever is most appropriate); this means CoCoALib would no longer be C++03 compatible.
