Hello,
I have problems to compile the following C++ class with an internal enum
definition:
*foo.h:*
class Foo {
public:
Foo();
enum Bar {
Bar1 = 1,
Bar2 = 2
};
Bar getBar( ){ return Bar1; };
};
*foo.cpp:*
#include <stdio.h>
#include "foo.h"
Foo::Foo()
{
printf("Constructor of Foo\n");
}
#include "glue.cpp"
*foo.idl:*
enum Foo_Bar {
"Foo::Bar1",
"Foo::Bar2"
};
interface Foo {
void Foo();
Foo_Bar getBar();
};
*build flow:*
python ${EMSCRIPTEN}/tools/webidl_binder.py foo.idl glue
emcc foo.cpp --post-js glue.js -o foo.js --memory-init-file 0
*emcc -v:*
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld)

Any idea what I am doing wrong? Thanks for your help!
