错误:
Undefined symbols for architecture x86_64:
"_adler32", referenced from: _lz_adler32 in liblibquickmac.a(lua_zlib.o) _png_icc_set_sRGB in libcocos2d Mac.a(png.o) "_adler32_combine", referenced from: _lz_adler32 in liblibquickmac.a(lua_zlib.o)
解决:
在cocos2d_libs.xcodeproj工程的Link Binary with Libraries中添加上zlib库即可。
zlib库在external/zlib中
