I don&#x27;t really understand their build system so not sure how to fix this cleanly but I added:<p>#define NOCRYPT (1)
#define NOUNCRYPT (1)
at the top of .&#x2F;third_party&#x2F;zlib&#x2F;src&#x2F;contrib&#x2F;minizip&#x2F;zip.c and unzip.c<p>And that got past the zlib errors on yosemite and built some of the demos (I will post some screenshots on twitter @joeld42, but it&#x27;s just boxes and stuff). However, there was a linker error later with some json parser (maybe it was in the tests? I can&#x27;t even tell) that I didn&#x27;t figure out yet.<p>I also had to install &quot;ninja&quot; because apparently it needs like six different build systems.<p>The &quot;ios&quot; targets build... but I don&#x27;t know what to do with them. I ended up with a directory full of .app files. Maybe zip them and rename them ipa?<p>Anyways, it looks like there&#x27;s some cool stuff in there but there&#x27;s a ton of dependencies and it doesn&#x27;t really feel &quot;lightweight&quot;. I&#x27;ll definitely keep an eye on this one but it really could use more documentation for people not familiar with google&#x27;s ecosystem.
