buildroot and emscripten

[Matt Flax]

Right now, to build a more complex software system with emscripten, it is difficult. Are there any auto-build systems for free or other software out there which support emscripten ?

To release a more complex WASM tool, like libsox (https://www.npmjs.com/package/sox-element) I have a hand written script to build all of its dependencies.

It would be really useful if we could select and build more complex WASM packages and their dependencies automatically using something like buildroot.

For example, say I wanted librsync and all its dependencies to be built so I can integrate it into a WASM package. Or ffmpeg and wanted the buildroot system to build any dependencies.

One idea is to work emscripten into buildroot's external toolchain / buildtools . This would allow one to select a number of packages and have their shared libraries all built for us and installed into a system directory in the standard development approach (/usr/include, /usr/lib, pkg-config, etc.).

This idea has come up before and I think there is general support for this direction:

See:

https://github.com/emscripten-core/emscripten/issues/9353

and:

https://github.com/emscripten-core/emscripten/issues/9414

I personally would like to first move towards a more conventional use of `--sysroot` as a first step.

cheers,

sam

Sure - the conventional "--sysroot" can be used if it works.

I replied to that issue : 9414
