It looks like you're loading the JS file from a different URL than the WASM file:
http://www.coolprop.sourceforge.net vs http://www.coolprop.dreamhosters.com:8010 The easiest solution is to host all files (.html, .js, .wasm) from the same domain (so either all files on sourceforge, or on dreamhoster, but not both). The complicated solution (which I haven't done so far) is to change the configuration of the dreamhoster webserver to accept cross-origin requests from the sourceforge domain (assuming dreamhoster even allows this sort of configuration). Google for 'CORS whitelist' or similar. On Sunday, 31 March 2019 00:27:54 UTC+1, Ian Bell wrote: > > I have an enscripten-wrapped C++ library, and running it in a local > webserver works fine.
