Browser instantiation of lumbda-c.wasm failed with:
Aborted(LinkError: import object field 'js_lumbda_bend_call'
is not a Function)
The wasm correctly required env.js_lumbda_bend_call as a function
import, and the EM_JS-generated function existed in the glue —
emcc placed the function declaration at depth 0 of createLumbdaC
where wasmImports lives, so it SHOULD have been hoisted into scope
at instantiate time. It worked in node test runs but threw on
browser load. The exact emcc-version cause is fuzzy; the fix is
to use the textbook mechanism instead of guessing.
New file wasm/c/bend-call-library.js — Emscripten JS library with
mergeInto(LibraryManager.library, { js_lumbda_bend_call: function(...) }).
mergeInto lands the function directly inside wasmImports under the
mangled name _js_lumbda_bend_call (auto-prefix), wired to the
js_lumbda_bend_call import. No scope guessing.
lumbda_wasm_entry.c — drops EM_JS, keeps the C wrapper bi_bend_call_wasm
and declares extern int js_lumbda_bend_call(...) so emcc emits the
env import that the library fills.
wasm/Makefile — adds --js-library c/bend-call-library.js to C_LDFLAGS
and lists the library as a dependency so changes trigger a rebuild.
Verified: deployed glue at lumbda.com now contains the mergeInto
binding (js_lumbda_bend_call:_js_lumbda_bend_call inside wasmImports).
End-to-end smoke via mocked XHR in node returns the expected
(ok pong) round-trip from the demo's first probe step.
