ReferenceError: FS is not defined

[bobajeff]

Ive compiled clang to js and I'm pretty sure it uses the filesystem but emscripten didn't seem to include the FS API so I'm getting:
ReferenceError: FS is not defined

When trying to use it. Is there a commandline argument to force emscripten to include it?

It should be there by default, unless you build with --closure which can minify it out, or NO_FS which will not include it.

I looked into the clang.js file and it looks like it's in there. I'm starting to suspect that the problem is clang.js isn't being loaded but my other script calling on FS is being ran anyways.

Just tried the onerror attribute on the script tag for clang.js and it didn't get triggered. So apparently it is being loaded. I must be missing something that's happening.

Well, I did a few tests:
First I removed the clang.js script tag and it gave the same error as before. I also tried to just do (with the clang.js script tag) Module.callMain and it says "TypeError: Module.callMain is not a function". So it again seems like clang.js isn't loading.

I ran the page in slimer.js and it gave out:

Script Error: NS_ERROR_DOM_BAD_URI: Access to restricted URI denied

Stack:

-> file:///home/ec2-user/build/test/testpage/smallfunc/clang.js: 1

Slimer.js broke after the this so I haven't been able to do any other tests.

Try running the page from a http:// URL. That should avoid the BAD_URI message.
