8. my code is:
9.
10. #include <math.h>
#include <emscripten.h>
#include <emscripten/bind.h>
#include <emscripten/html5.h>
using namespace emscripten;
class FOOWASMInterface
{
public:
FOOWASMInterface() { }
float bar(float value, bool up)
{
if(up)
return ceil(value);
else
return floor(value);
}
};
EMSCRIPTEN_BINDINGS(FOOModule) {
class_<FOOWASMInterface>("FOOWASMInterface")
.constructor<>()
.function("bar", &FOOWASMInterface::bar)
;
}
11. and my compile instruction is:
12.
13. em++ -O3 -std=c++14 -s ERROR_ON_UNDEFINED_SYMBOLS=0
foo_bindings.cpp --bind -s WASM=1 -o foo.js
14.
15. and my javascript is:
16.
17.
*Module = { onRuntimeInitialized: function () { var FOOLib = new
Module.FOOWASMInterface(); var value = FOOLib.bar(5.4, true);
console.log('5.4 ceil' + value); value = FOOLib.bar(5.4, false);
console.log('5.4 floor' + value); } };*
What mistake am I making?
