Description
The code executed by --embind-emit-tsd appears to expect that the target was WASM and therefore fails when the WASM=0 option is set.
Please include the following in your bug report:
Version of emscripten/emsdk:
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.53 (ce5114b)
Failing command line in full:
emcc -s WASM=0 -lembind main.cpp --embind-emit-tsd interface.d.ts -v
Aborted(TypeError: Module.__wasm2jsInstantiate__ is not a function)
/tmp/emscripten_temp_o4b8c1as/tsgen_a.out.js:136
throw ex;
