This looks like this LLVM linking issue, https://github.com/kripken/emscripten/issues/4234
There are some possible workarounds mentioned there. Otherwise, this may be fixed by an LLVM update. In the next-merge branches in all three repos is the next update, which might happen soon. If you want you can build that and see if it helps. On Thu, Aug 4, 2016 at 3:13 PM, caiiiycuk <[email protected]> wrote: > Hi. I trying to build cocos2d with emscripten.
