Hi people, Happy to begin my first review of a Boost library ! Thanks to the author for this opportunity - and the lib ;) I've had some tiny problems compiling and running the tests with Apple Clang (14 and 16). It seems linking to boost_url was missing so I had to edit the CMakelists.txt. I don't know if it's a mistake from my side or an edge-case for the build system, but anyway now that it builds I can not find how to have the tests pass: 1/1 Test #2: boost_test_extension_simple_scalar ...***Failed 0.02 sec Parse error near line 1: no such function: load_extension SELECT load_extension('./simple_scalar'); I would understand the author wants to avoid the rabbit hole of covering "how to build and run for every possible system", but having at least some indications in the docs could helpful ! :D It feels a bit weird to ask such frivolity on the ML, thanks for your patience, All have fun with the review !
