Are there instructions for developers that I've missed?
There are some instructions here:

Thanks!
I was expecting developer guidelines in the github readme, not in the actual library docs! doh! I have made a PR #285 and after some trial and error (I only have VS2015 and VS2017 available to test locally) I think I have something. However, in my test I throw and catch exceptions: int test() { std::exception_ptr ep; try { throw 42; } catch(...) { ep = std::current_exception(); } try { std::rethrow_exception(ep); } catch(int i) { // return zero on success return i == 42 ? 0 : 1; } return 1; } But the CI jobs have gcc and clang configured to compile without exception support! And I get errors like: libs/config/test/boost_no_cxx11_hdr_exception.ipp:22:5: error: cannot use 'throw' with exceptions disabled throw 42; ^ libs/config/test/boost_no_cxx11_hdr_exception.ipp:20:3: error: cannot use 'try' with exceptions disabled try ^ I have two questions: 1) Where are exceptions disabled in the CI jobs? I can't find it in the .travis.yml, but I can see e.g. clang being invoked with -fno-exceptions 2) How can I test proper support for std::current_exception() and std::rethrow_exception() if exceptions are disabled for the test? Thanks!
