Hi all,

I have a project that compiles C++ to wasm/javascript using emscripten. But 
I am having trouble getting the class defined via embind to instantiate in 
my javascript. 

This is my makefile: 

# webassembly
CC=em++
CFLAGS=-std=c++11 -s WASM=1 -s ALLOW_MEMORY_GROWTH=1 -s SAFE_HEAP=1 -Oz -g4 
-s ASSERTIONS=1
DEPS=-I eigen 
LINK=-s LINKABLE=1 -c

wasm: Settings.h Settings.cpp Vertex.h Vertex.cpp Edge.h Edge.cpp 
BarnesHutNode3.h BarnesHutNode3.cpp LayoutGraph.h LayoutGraph.cpp 
DynamicMatching.h
$(CC) $(CFLAGS) $(DEPS) $(LINK) Settings.cpp -o build/Settings.o
$(CC) $(CFLAGS) $(DEPS) $(LINK) Vertex.cpp -o build/Vertex.o
$(CC) $(CFLAGS) $(DEPS) $(LINK) Edge.cpp -o build/Edge.o
$(CC) $(CFLAGS) $(DEPS) $(LINK) BarnesHutNode3.cpp -o build/BarnesHutNode3.o
$(CC) $(CFLAGS) $(DEPS) $(LINK) LayoutGraph.cpp -o build/LayoutGraph.o
$(CC) $(CFLAGS) $(DEPS) $(LINK) DynamicMatching.cpp -o 
build/DynamicMatching.o
$(CC) $(CFLAGS) $(DEPS) build/Settings.o build/Vertex.o build/Edge.o 
build/BarnesHutNode3.o build/DynamicMatching.o --bind -s ENVIRONMENT='web' 
-o build/fourd.js

I'm trying to follow best practices for a web project, so I experimented 
with rollup and webpack, but I thought my issue might be more fundamental 
than that.

When I include the generated fourd.js in a webpage, I get a "run is not a 
function" error in Firefox. 

Is there something wrong with my compilation process? 

Josh
