make problem on macosx about box2d.js HOT 7 OPEN

I had to make these changes to get it to build on Mac OS X:

bunnyhero@0ef6eac#Makefile

from box2d.js.

thanks, but unfortunately this just leads to another problem:

cpp -xc++ -DEM_NO_LIBCPP -IBox2D_v2.2.1 root.h > box2d.clean.h
# CppHeaderParser doesn't like Xcode's cpp output: this fixes it.
sed -i -e 's/__signed/signed/g;s/__const/const/g' box2d.clean.h
python 1/tools/bindings_generator.py box2d_bindings box2d.clean.h -- '{ "ignored": "b2Shape::m_type,b2BroadPhase::RayCast,b2BroadPhase::UpdatePairs,b2BroadPhase::Query,b2DynamicTree::RayCast,b2DynamicTree::Query,b2ChainShape::m_nextVertex,b2ChainShape::m_hasNextVertex,b2EdgeShape::m_hasVertex3,b2EdgeShape::m_vertex2,b2EdgeShape::m_vertex3,b2Mat22,b2Mat33" }' > bindings.out

Oh yeah, I forgot. You also have to add a line like this:

EMSCRIPTEN=/Users/bunnyhero/dev/github/emscripten

except substituting the path to your emscripten directory.

You can either add that line to the Makefile, or (as I did), put it in a file named Makefile.local in the same directory as the Makefile (it will get included).

thanks, this seems to have fixed everything!

This doesn't work for me:
cpp points to apple's version of clang that uses a different version of llvm.

should I use {/path/to/correct/clang -E} instead of {cpp} ?
that compiles but with lots of warnings (eg: has C-linkage specified, but returns user-defined type), and the resulting html doesn't work properly.

This fix is not working for me either. I tried installing the 3.2 and 3.3 version of LLVM.

I followed these instructions manually as well as with brew:

I'm on osx 10.9.3. Here's the errors I'm currently seeing (with LLVM 3.2):

I switched over to an Ubuntu 14 VM with similar results:

I was finally able to get a emscripten build working on box2d on Ubuntu 14 by following these instructions https://github.com/kripken/emscripten/wiki/LLVM-Backend#getting-fastcomp for setting up LLVM and clang. I followed the exact same steps for Mac os 10.9 and still see these errors: https://gist.github.com/jarbot/0af2ace168d3b12030e0
