error: 'HEAPF32' was not exported. add it to EXPORTED_RUNTIME_METHODS in console

[lilrooness]

I am compiling a project with emscripten and cmake and I'm getting this error repeatedly printed to the console in chrome & firefox

Uncaught RuntimeError: Aborted('HEAPF32' was not exported. add it to EXPORTED_RUNTIME_METHODS (see the Emscripten FAQ))

When I try to add HEAPF32 to EXPORTED_RUNTIME_METHODS I get a linker error saying that this symbol does not exist.

I am using these extra linker flags:

-s USE_GLFW=3 -s ASSERTIONS=1 -s WASM=1 -s ASYNCIFY -s GL_ENABLE_GET_PROC_ADDRESS=1 --preload-file res --preload-file proj

(res and proj are both directories)

I'm not quite sure how to proceed from here. Any suggestions are welcome.

I'm using the mingw toolset installed by emsdk: emsdk\mingw\7.1.0_64bit

I'm using latest emscripten: b2436aa tag: 4.0.21

Fixed by adding this to the linker line:

-s EXPORTED_RUNTIME_METHODS=HEAPF32

I'm unsure what the root of the original failure was though

This should not be needed unless you yourself and adding/writing JS code that references HEAPF32. if the reference is coming from emscirpten-generated JS code that dependency should be automatic.

Oh, but this reference does look like it must be external, so you must have some external code that depends on this I guess?
