When compile, it shows this error shared:ERROR: Js/ExternPre_Compiled.js: Input file has an unknown suffix, don't know what to do with it!

The problem The compiler options --extern-post-js --extern-pre-js both have same error.

I changed js files to root directory of project. Same error. I change to lowercase filenames and without special chars, same error as:

I checked the filenames, they are existing.

What version of emscripten are you using (emcc --version)

Most likely you are using a version older than 1.39.15 where these flags are not supported.

PS C:\Users\Megam> em++ --version

Yup, you need 1.39.15 or above to use those flags
