std::exception_ptr usage is replaced with rxcpp::util::error_ptr which will typedef to std::exception_ptr when exceptions are enabled. When exceptions are disabled this will typedef to an internal error type that can retain the "what" error message. Additionally std::current_exception() and similar usages are replaced with rxu::current_exception which uses error_ptr instead. Lastly all try/catch/throw keywords are replaced with either RXCPP_TRY, RXCPP_CATCH, rxu::throw_exception or similar. Note that try/catch/throw keywords cause a compilation error with -fno-exceptions. Trying to access most of the std::*exception* functions will call std::terminate at runtime. Tests using exceptions must be disabled by passing --nothrow to the check2 test runner. Change-Id: I0b95ae2e323653a17c3b733d165ecf87a014c315

That sounds straightforward enough to fix. Clarifying questions:
(Note that I am unfamiliar with CMake best practices, so I would be glad to hear of a specific suggestion if you have one in mind). |

Good points. Regressions will be much less likely is there is a cmake option and a ci pass for this. I’ll add something for those if you don’t get to it first. :) I am certainly not a cmake proficient but I did recently add some cmake options to change compiler flags in the facebookresearch/pushmi repo that could be a start. |

Shall we continue our discussion on how we can upstream this now that I have rebased everything to tip-of-tree ?
