html version of moai sdk is not working

After successfully building a linux version of moai sdk, I am trying to build a html host, which is really a hard thing to do.

run build-html.sh first time

In file included from /home/jackie/Desktop/moai/moai-community/sdk/moai/src/zl-util/ZLDeviceTime_posix.cpp:32:
In file included from /home/jackie/Desktop/moai/emsdk/fastcomp/emscripten/system/include/emscripten.h:1:

      different types ('struct _IO_FILE' vs 'int')
typedef struct _IO_FILE FILE;
                        ^

typedef int ZLFILE;
            ^
1 error generated.

so I change typedef int ZLFILE to typedef FILE ZLFILE and it worked

run build-html again

[100%] Linking CXX static library libmoaishared.bc

Scanning dependencies of target moaijs
shared:ERROR: unclosed quoted string. expected final character to be ''' in ''FS_unmount'\\ '

so I deleted the space after the FS_unmount in file cmake/hosts/host-html/CMakeLists.txt

and run it again, I got shared:ERROR: undefined exported function: "_AKURunScript"
so I deleted _AKURunScript and repeat the process until it finally builds

I have run pito host run html successfully, but the webplayer is not working at all. My browser gives me error message like TypeError: Module.cwrap is not a function

Thank you!
