OSX build fails on zlib.h being missing.

[juj]

Tried to build on OSX with latest emscripten, but the build aborts on a missing include zlib.h:

Did OSX builds work at some point - is this a regression? Or I wonder if OSX hasn't been used before to build?

[juj]

Oh, I see we had this change: emscripten-core/emscripten@409051c which breaks it.

[kripken]

What are you building there?

If that is a project that uses zlib, it should include the zlib headers. We had them by mistake in our system headers, but we don't have the code there, so we removed the header.

I was building BananaBread for Emscripten using these instructions: https://github.com/kripken/BananaBread

[kripken]

Ok, i guess that project needs to import zlib headers then.

Was this fixed in 0b96d97 ?

[kripken]

Seems so, at least in that branch.

I've checked out the worker branch, but when I run emmake make, I still get 'zlib.h' file not found. Do I need to add an addition -I flag?

[kripken]

No, we just need to copy zlib.h into here somewhere, I guess. I thought I already had into at least one branch, but maybe no.

[nickdesaulniers]

If I add -I. (from @juj ), compilation fails because zlib.hL34 tries to include zconf.h.

[nickdesaulniers]

If I simply curl zconf.h into the dir, building proceeds. PR inbound.

Unfortunately, looks like we can't use crunch on OSX. @juj seems to already have run into this one...

[juj]

You can install crunch via Emscripten SDK on OSX (type ./emsdk install crunch-1.04). I hacked together a build from the patches that were provided in that issue, and packaged the resulting build up to emsdk.

[nickdesaulniers]

@juj , can I install crunch given emscripten's source, instead of having to install the sdk?
