Bonjour Stéphane.
The missing files are now installed.
There's a new error, only when I use the -emcc option:
$ faust2webaudioasm -emcc noise.dsp
Compiled with 'emcc'
aborting from js compiler due to exception: unknown vector type <4 x

output[0][-3000:] AssertionError: Did not receive forwarded data in an
output - process failed? We only got: _pre_phi_i=$88; }
I installed emscripten 1.10 from a Ubuntu repository;
should I try to install emscripten from scratch?
A related question, probably documented somewhere:
What's the use of the -emcc option? Is it for optimization?
Is it "better" than the internal asm.js backend?
Thanks
