Hi,
I have this simple use case:
hello-worker.html -----------------------8<---------------------
<!doctype html>
<html lang="en-us">
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Emscripten Test</title>
<script type="text/javascript">
var w = new Worker("hello-worker.js");
</script>
</body>
</html>
hello-worker.html -----------------------8<---------------------
hello.c: -----------------------------8<------------------------
#include <stdio.h>
void foo(void)
{
printf("foo\n");
}
int main() {
return 0;
}
hello.c: -----------------------------8<------------------------
hello-worker.js ---------------------8<-------------------------
importScripts("hello.js");
if (Module) {
console.log("Module is defined");
}
hello-worker.js ---------------------8<-------------------------
I compile hello.js with:
EMCC hello.c -s NO_EXIT_RUNTIME=0 -s ASSERTIONS=1 -s
EXPORTED_FUNCTIONS="['_foo']" --closure 1 -O2 -o hello.js
For some reasons when the hello.js code is loaded from the worker,
Module is not defined and I get:
ReferenceError: Module is not defined hello-worker.js:3
"run() called, but dependencies remain, so not running" hello.js:4
This only happens with -O2 --closure 1, it will work with -O2
--closure 0 or with -O1 --closure 1.
The equivalent non-worker code is working fine (that is Module is
correctly referenced):
hello.html -----------------------8<---------------------
<!doctype html>
<html lang="en-us">
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Emscripten Test</title>
<script type="text/javascript" src="hello.js"></script>
<script type="text/javascript">
if (Module) {
console.log("Module is defined");
}
</script>
</body>
</html>
hello.html -----------------------8<---------------------
BTW this is probably affecting Broadway, see
https://github.com/mbebenita/Broadway/issues/45
Can someone explain why this is happening? Should I file an issue?
TIA
