Package: emscripten
Version: 3.1.6~dfsg-5
Severity: important
X-Debbugs-Cc: apo@debian.org
Dear maintainer,
emscripten fails to build from source with the latest version of
binaryen, currently 116, in experimental.
I'm attaching the complete build log. I intend to upload a new version
of binaryen to unstable next year because I know that emscripten has
no real maintainer and is currently maintained by the QA team. I will
ping this bug report again before I do the upload but I hope someone
else can look into this problem before that.
I wonder if emscripten should embed the exact version of binaryen
required to build the package to avoid a circular dependency (because
then I could use emscripten to build wabt.js for example).
These are the last log lines when emscripten fails:
embuilder:INFO: building struct_info

emscripten:ERROR: emscript: failure to parse metadata output from wasm-emscripten-finalize. raw output is:
