Its also important to remember that emscripten sometimes does compilation at link time, within the driver even if you don't ask it to explicitly. This means that while many of the options can be passed just to the linker, the linker flag much include all the compiler flags. i.e. link flags must be a superset of the compile flags. Otherwise you could end with some sources compiled with different options. On Tue, Oct 2, 2018 at 7:21 AM Nolan Darilek <[email protected]> wrote: > > Ah, perfect, thanks!
