Build fails with error "unknown file type: build/fdk-aac/.libs/aac-enc.bc"

[pawelkaczmarek]

Hi,

I'm trying to build the library from sources using the latest fdk-acc, but have encountered an error.

1. I clone fdk-aac.js and fdk-aac into /build.
2. run make command in fdk-aac.js*
3. On building aac-enc.js it fails with error:

mbp-pawel:fdk-aac.js pawel$ make

make: *** [aac-enc.js] Error 1

File pointed in error (build/fdk-aac/.libs/aac-enc.bc) exists and seems ok.

@salomvary Do you maybe have an idea the error might be due to emscripten config, fdk-aac build or something else? I'm using latest emsdk (2.0.15).

*(I think the fdk-aac.js Makefile has a typo – it lacks " \ " at the end of the line 21).

Any help much appreciated 😉

[salomvary]

I have not used Emscripten since publishing this, no idea what might have gone wrong. You can try using an older Emscripten version, something from around the time when I created this. If that succeeds, please let me know so that I can document it on the repo.

Fixed the Makefile typo, thanks!

And should @pawelkaczmarek also use the lib fdk-aac version which you used to build this with? (since he pointed out using the latest one now...? 🤔 )

[salomvary]

@tchakabam Good point. Also, pull requests to upgrading either fdk-aac or Emscripten or both are welcome!

[jiyeyuran]

@salomvary what version of Emscripten did you use? I got the same problem.

No idea, probably whatever the latest was when I did these things :)

[jiyeyuran]

ok, that's the version 4 years ago.

Yep, something like that.

Finally, I figured it out. This PR will work with the latest Emscripten.
