I am trying to make a simple test using the "Filesystem emulation". As soon as I add cheerp::FilePreloader files(preloadCallback, "CemHyds-dat.lst"); to my test file I get the following error in the broswer:

Uncaught (in promise) Error: this should be unreachable
    __dummy http://127.0.0.1:8080/gemsw.js:57
    promise http://127.0.0.1:8080/gemsw.js:78
    promise callback* http://127.0.0.1:8080/gemsw.js:69

I am wondering if someone else can preproduce this error or there is something that I do wrong.
See: test-wasm2.zip

I used: Cheerp 1601094897-1~bionic clang version 9.0.0 (based on LLVM 9.0.0svn)

If someone could try to test the example I attached and see if the error can be reproduced (compile and test in the browser). Thanks.

It is not possible for us to reproduce this problem without additional information.

What is the exact build command you are using?

Please verify that the filesystem emulation library has been correctly linked: -lposixcompat should be passed during the linking step.

Thanks @alexp-sssup! this solves the problem.
